Aphids on indoor, garden, Chinese roses: how to fight, how to treat and spray, how to get rid of folk remedies, what to do with home flowers?

Pest types

It can be of different types, but they are all united by high fertility and activity. On the plant, these bugs can be seen with the naked eye.

White indoor aphid affects roses growing at home. Translucent, small, no more than 0.5 mm in size, these insects are capable of completely covering the entire plant in a short period.
Mealy aphid prefers greenhouse roses. It has an oval body with a white coating and setae on the sides.
Green rose aphid settles on roses growing in the open field. Usually these small green insects with brown antennae choose young shoots and buds for habitation.

Reasons for the appearance of sticky plaque

A sticky leaf in any plant means that organic waste with a lot of carbohydrates is deposited on its surface.

In a healthy plant, this is possible only if something that adheres to the outer covers of the leaf has fallen onto the leaf blade from the outside. This happens rarely. And if all the leaves of a plant suddenly become covered with something sticky, these are signs of a pathology that develops so quickly that soon not only a few leaves and the whole plant are covered with a sticky mass, but also the nearest space around. This indicates the presence of a constant process of violation of the integrity of the leaf blade.

Harm done

Aphids cause tremendous damage, as they feed on plant tissues and suck out plant juices. Young shoots, flower and leaf buds are most affected by aphids. As a result, leaves and whole branches are deformed and turn yellow, and the buds, not having time to bloom, fall off. The plant affected by aphids weakens, its resistance to diseases and temperature extremes decreases.

Also aphids give off honeydew - sweet and sticky, similar to syrup. These secretions coat the leaves and stems of the rose bushes, making the plant susceptible to fungal infections and increasing the risk of black mold. In addition, aphids are a carrier of viral diseases. Therefore, if a pest is found on both home and garden flowers, it is necessary to urgently begin to deal with it.

Thank you for such attention to my problem! Of course, I understand that pruning is not worth doing now) It's just that I periodically raise this question, but my hand does not)) The problem is that it is very difficult to manually process all the leaves - I don't get it, and it just takes the sea for it ((Hibiscus blooms almost all spring and early summer, during winter it also periodically throws out buds. It grows very quickly, especially in spring, new shoots are soooo strong! The leaves are big, like burdocks. This spring, the hand did not rise again to cut off at least those shoots that the passage is blocked off - each had a bud! During the heating season and the summer heat, it happens that leaves turn yellow and fall off. But very moderately, no leaf fall. Spraying and a little more abundant watering helps. I'm afraid to flood because I don't know what kind of land is there in a flowerbed (most likely an ordinary garden one), is there drainage ... The earth has not changed, most likely from the moment the plant was planted, and to be honest, I have little idea how this can be done. top layer - otherwise the earth becomes very heavy, tight. Our Spartan grows near the southwest window, there is enough light in the summer. In winter, we do not organize any special supplementary lighting, we just turn on the light in the room with the onset of darkness.It burns until 12 at night ... can it be considered supplementary lighting? :) To my shame, I do not indulge him with top dressing ... the last time in the spring I stuck long-playing fertilizer sticks into the ground. The instructions said that this is enough for several months ... well, somehow, just after reading articles on the Internet, I began to realize that it would be nice to feed the pets. In general, I read flower articles with horror ... I did everything wrong !!!

Where and why does it appear?

Possible causes of aphids:

In the soil into which the bush was transplanted, aphid eggs were laid for the winter.
The newly acquired bush is already affected by aphids.
A small number of insects and birds that feed on aphids.
Spread with the help of an ant.
Ants are aphids' best friends. They feed on honeydew and help spread the pest.
Ants protect aphids from other insects and transfer them from one plant to another, contributing to the emergence of new colonies and a source of food for themselves. The parasites form a colony in a few days, and during the season the number of colonies on the bushes can reach 50. Ants keep the eggs of aphids for the winter, and in the spring they carry them around the plants.
Flying female aphids, settler - after fertilization, they fly away from the colony to lay their eggs in a secluded place.
Pests can get on indoor roses from the street on clothes or with pets.

Diseases of indoor hibiscus

Chlorosis or why hibiscus leaves turn yellow and fall off

One of the problems with hibiscus is leaf chlorosis, that is, loss of color. The leaf blade becomes pale green, almost yellow. Also, foliage may begin to fall off. This is a sign of a lack of iron. The easiest way to restore a rich color to the crown is to spray the plant with iron chelate. You should also change the fertilizer if it does not contain enough trace elements necessary for hibiscus.

Chlorosis in hibiscus: photo It is really difficult to find a good top dressing for these plants, therefore you often have to sort out various options.

Lack of nutrients (potassium, magnesium, zinc, sulfur)

The appearance of yellow spots, for example, after transplanting into new soil, can be caused by lime content or lack of nutrients. Then you should replace the soil or use special preparations to make up for the lack of certain substances.

With a lack of zinc, the leaves become smaller, specks appear on them.
Lack of sulfur is expressed in the browning of the leaf edge.
When there is little magnesium, chlorosis occurs between the veins - the so-called "marbling" of the leaf, sometimes with the appearance of dark spots.
The lack of potassium is expressed in the death of the leaf edge, which looks like a burn.

If the above methods do not work, the chlorosis may have been caused by viruses. Infections are carried by various pests, if such symptoms occur, you need to get rid of insects, and treat the hibiscus with fungicides.

How to fight?

You can get rid of the pest on indoor and garden flowers both by folk remedies and by chemical and biological methods.

Folk remedies

These are the most gentle and environmentally friendly measures for aphid control. Many products do not destroy pests, but scare them away from treated plants. They also fertilize the soil, are safe to use (if processed correctly), are available and cheap.

But there are also disadvantages to folk methods. So, preparations are quickly washed off by rain or watering and usually requires repeated re-treatments.

Do not spray plants with any means on a bright sunny day, as burns may occur on the leaves (drops are imitation lenses).

General rules:

adding laundry or green soap to the solution;
treatment with stems and leaves (not soil);
the underside of the leaves must be processed - the favorite habitats of aphids;
spraying in cloudy dry weather, and preferably in the evening, when the working day is over for beneficial insects;
watering plants 2-3 days after treatment.

Basic recipes and methods of application:

The most toxic of the folk methods is a solution of ammonia (ammonia). When using it, you must use gloves and a respirator. To obtain a solution, mix 2 tablespoons of ammonia and 50 g of grated soap in 10 liters of water, then pour a bush from a watering can. Repeat the procedure every 2 weeks (but use a freshly prepared preparation - ammonia quickly evaporates).
Mustard will scare away both aphids and ants. Take 10 g of mustard per liter of water, insist in warmth for 2 days and dissolve in 5 liters of water. Spray the plant, repeat after a week.
Dry mustard can be sprinkled on anthills and ant paths to scare them away.
Grate 250 g of simple laundry or tar soap and dissolve in 10 liters of water. Spray the bush from a plastic bottle with holes in the lid (the spray can clog). After 2-3 days, wash off the soap film from the plant so that it breathes better.
Green soap is more environmentally friendly than laundry soap. Mix 250 ml of soap in 10 liters of water until foam forms and spray in the same way as with laundry soap. It is necessary to process the bushes in this way three times a year - in spring, summer and autumn.
Infusions and decoctions of herbal insecticides - fresh potato tops, garlic cloves, onions, chamomile, celandine, aconite, tobacco, hogweed and others. Pour about 250 g of grass with hot water, boil for half an hour and leave for 2-3 days in a sealed container. Strain, dilute with water 1: 3, add soap and spray on the affected bushes.

Chemical and biological methods

It is undesirable to use chemicals to combat aphids on roses. The specific smell of chemicals will interfere with the aroma of flowers. In addition, petals treated with chemicals cannot be used for cosmetic and culinary purposes. And do not forget about the danger of pesticides for crops growing next to roses.

But if, nevertheless, there is a need to use chemicals, they are easy to purchase in specialized stores. The main thing is to decide what exactly to spray the plants with.

Inta-vir can be in tablets or powder. Rose bushes are sprayed with a solution of the drug before flowering. It can be used for both garden and indoor plants.
Fitoverm brings minimal harm to the environment. Indoor roses are sprayed with them when aphids are detected, and garden roses - before flowering.
Aktara is often used by gardeners. A solution of this agent is watered and sprayed on the plants. After watering, the drug is distributed over the tissues of the leaves and retains its effect for up to 2 months. The Commander and Confidor-extra are used in the same way.
Contact preparations such as Fufanon, Karbofos destroy insects in contact with the solution.
Intestinal chemicals: Akarin, Aktellik, Agravertin, Decis-profi, Aktofit.

When using pesticides, safety measures must be observed. First you need to read the instructions for use, which describes how to prepare and use the solution.

When working with chemicals, be sure to protect yourself - gloves, a dressing gown, glasses, a mask on your face. At the end of the treatment, take a shower, change clothes.

The biological methods of controlling aphids include the use of natural enemies of these pests - birds and insects. When using pesticides, there is a high risk of destroying insects that eat aphids. To avoid this, you can water the roses with a stream of water from a hose for a week every other day. Aphids, washed away from the bushes, will drown, the rest will be eaten by insects. This method will help contain the reproduction and spread of aphids in the garden.

One ladybug can eat up to 250 aphids per day. They also like to eat aphids, lizards, wasps, hoverflies, aphid lion, ground beetles, lacewings, weevils.

You can also plant plants that attract beneficial insects. This will maintain a natural balance between beneficial and harmful insects and reduce the number of aphids. It is good to plant such plants as marigolds, lavender, garden buckwheat, calendula, thyme, sweet clover, fragrant dill, tansy and others.

How to process hibiscus?

Hibiscus, or Chinese rose, is popular with flower growers due to its endurance and ease of maintenance. But this flower can also be subject to aphid infestations, so every gardener should know how to process a Chinese rose. If the lesion is small, then a soap solution will be sufficient. In case of significant damage, it makes sense to use chemicals, for example, Inta-vir, Aktara.

Diseases and their causes

In addition to insect infestations, your flowers can be exposed to diseases. Diseases of hibiscus, if left to chance, can cause the death of the plant. Rotten roots, leaves starting to dry out are all clear signs that the hibiscus needs help. It will not be about various types of rot, when the plant has rotted or its roots have dried up, but about diseases that affect the state of the foliage of the flower. So let's take a look at the main leaf diseases and their treatments.

Chlorosis

Chlorosis is nothing more than the loss of color by the leaves. The diseased leaves rapidly lose their color and become very pale, even slightly yellowish. The disease is most dangerous because the leaves can not only lose their color, but over time they can begin to fall off. Thus, if you do not take any measures, your hibiscus may soon be completely naked.

Sunburn

Another attack that poses a significant danger, but in essence is not a disease, is a sunburn. Everything is simple here: sunburn occurs as a result of a breach of conditions of detention. Hibiscus, like the vast majority of plants, cannot stand direct sunlight. Therefore, if you forget about it and place it in a place where it will be directly affected by them, be prepared to accept the consequences in the form of sunburn.

Also, this attack may appear if you kept your plant in the shade for a long time, and then sharply put it in a bright place. In this case, it is not even necessary that direct sunlight falls on it - a simple change of scenery will be enough. In addition, sunburn can occur even if the leaf seems to stick to the glass.

A sunburn looks like a small reddish or yellowish dry spot on the surface of the leaf plate. It is better to take measures to save hibiscus immediately, because the longer you delay, the more rehabilitation the flower will then need.

Preventive measures

Consider what to do so that after the destruction of the aphid, it no longer appears on the plants.

Prevention is very important in the fight against aphids.
It is necessary to carefully choose a site for the future rose garden, to properly care for flowers - watering, feeding, lighting.
Rose bushes should be regularly examined for pests, damaged and dried leaves, shoots, flowers should be removed.
About once a month, you need to wash the plants with a stream of clean water or soapy water.

There are many ways to combat pests, for every taste. But while observing all preventive measures and proper care of the rose, you will still have to resort to such measures much less often.

Why indoor hibiscus does not bloom and what to do in this case

One of the common problems with hibiscus is the lack of flowering. This may be due to:

with a lack of lighting - to lay buds, the plant must be in direct sunlight for at least 4 hours a day,
lack of timely pruning - buds appear only on new shoots,
damage by pests,
lack of food
lack of a dormant period in winter. From October to February, watering and feeding is reduced, the temperature is lowered to 15-18 degrees. It is believed that under these conditions flower buds are laid. But the plant can bloom in winter, with sufficient lighting.

In order for the hibiscus to bloom, it should be provided with a sunny location, timely pinching and pruning of shoots, rest in winter and abundant feeding in summer. It is also necessary to monitor the condition of the plant in order to notice the damage by pests in time.

The main mistakes in plant care

Hibiscus, aka the Chinese rose, is not a very capricious plant, and it is rather unpretentious in care. He forgives small flaws, but systematic violations of the temperature and water regime and other parameters necessary for him, of course, will not go away. The plant will begin to ache, wither, and if nothing changes, it may even die.

The most common mistakes in hibiscus care include:

Violation of the watering regime, which can lead to decay of the roots of the flower.
Watering the plant with polluted or hard water that did not have time to settle properly.
Lack of spraying necessary for the flower, especially in the hot season.
Hot and dry indoor climate.
Contact with leaves of direct sunlight.
Bad light.
Drafts indoors.
Untimely transplant
Improper feeding - lack of nutrients or "overfeeding".
Dust and dirt on the plant.

Long-term violation of the requirements for the care of the Chinese rose will certainly cause the development of diseases of the domestic hibiscus.

Prevention

To prevent the development of a second disease, the following preventive measures must be taken:

Temperature indicators should not go beyond the normal range - 18-22 degrees Celsius. Drying out and waterlogging are unacceptable.
Timely pest control. It is they that lead to deformation of the leaves and the development of diseases. For processing, use Peretrum, Aktofit.
It is best to use mineral complex fertilizers to apply nutrient formulations on a regular basis.
The air in the room should be moderately humid, but not dry.

Care errors leading to the appearance of aphids on roses

Occasionally, aphid infestation can be guessed by the appearance of ants in the house - the guardians of these insects.
Rosanna aphids, like all living organisms, need suitable conditions for the development of a colony. In the house, such conditions are created if flower growers make some mistakes in the maintenance of roses:

Mistake # 1. Abuse of nitrogen fertilizers.

Roses overfed with nitrogen have a loose and overly juicy tissue structure and are most susceptible to aphid infestation. Read also the article: → "Fertilizing roses in spring."

Mistake # 2. Non-compliance with quarantine for new plants.

Purchased indoor plants should not be immediately placed next to other house flowers. They should be in a separate room for several weeks.

Mistake number 3. Failure to comply with the rules of rose hygiene.

Indoor roses that receive a timely shower and pruning resist pest infestation better than unkempt roses. The warm microclimate of the apartments is favorable for the development of the aphid colony, so the plants need to be given special attention - especially in the summer.

Tip # 1. A weekly shower protects indoor roses not only from drying out, but also from the possible spread of parasites.

Possible consequences

This phenomenon has causes and consequences. The reasons are simple - microorganisms start on the plant that damage the leaves. As a result, juice flows from the wound of the leaf all the time.

Reaching a certain number, the pest forms a sticky cover on the leaves. Since he drinks the juice, his secretions are not only runny but also sticky. As a result, the leaf is covered with a continuous layer of a mixture of its own juice with the secretions of organisms that eat it.

This process can have the following consequences.

1. The plant loses water and nutrients.
2. Fungi, bacteria, viruses can settle on permanent damage, which can cause a new disease.
3. The sticky cover clogs the stomata, making it difficult for respiration and water evaporation.
4. Since the plant is not provided with sufficient oxygen and carbon dioxide, the formation of organic matter in the process of photosynthesis becomes unproductive. This leads to leaf loss and gradual wilting of the entire plant.
5. Closed with a sticky substance, the stomata cease to evaporate water. As a result, the movement of water from the root hairs to the leaves is slowed down. For this reason, the supply of minerals to the terrestrial organs of the plant also slows down. This is the reason for the deficiency of minerals. The intensity of bio and photosynthesis decreases. As a result, the plant ceases to bloom and bear fruit, gradually dying.

Thus, a sticky coating on the leaves of a plant is a signal of trouble. Who is the culprit of these troubles?

Whitefly lesion

This small flying insect should also be mentioned when describing ficus diseases and their treatment. It lives on the back of the hibiscus leaves. The leaves are covered with sticky spots and turn yellow.

To get rid of the whitefly, chemicals are usually used - "Fufanon", "Aktaru", "Iskra". Adult insects can be washed off with a stream of water, and the larvae, eggs and plaque can be removed with a swab with soapy water (100 g of crushed household soap, or better - tar soap for half a liter of water).

Basic methods of struggle

There are several ways to get rid of flowers from pests and prevent their spread. When choosing a method, it is necessary to take into account the intensity of infection, as well as the number of individuals and larvae. At the initial stages, folk recipes show effectiveness; in case of severe damage, it is recommended to use more radical measures. At the first suspicion of infection, it is necessary to examine the flowers and rearrange the affected plant to a safe place.

We suggest that you familiarize yourself with: Ammonia for indoor flowers, application and preparation of a solution against pests and for fertilizing plants

Chemical methods:

dichlorvos - Raid, Raptor, Neo - agents that instantly destroy both types of insects;
solutions - Kinmiks, Agravertin, Aktara, Bazudin, Fitoverm, Aktellik, Karbofos.
Each drug has its own characteristics, starting from the temperature level and ending with the concentration of the mixture; after the procedure, it is not recommended to water the plant for 3 days.
The use of chemicals requires compliance with safety measures, treatment is carried out in a respirator, rubber gloves and protective clothing.

Organisms that damage the leaf blade

It is difficult to identify a pest that destroys a plant. These are mainly insects or mites, that is, multicellular organisms. However, they are so small that it is difficult to see them. In addition, only a specialist can determine the type.

Nevertheless, it is necessary to know the enemies of plants. Here is a rough list of them.

1. Spider mites are the most common pests of indoor plants. They are arachnids. Their presence is usually detected by indirect signs. The stickiness of the leaves is the first sign. Then subtle cobwebs appear. If the plant is in bloom, the cobweb concentrates on the flowers. Chrysanthemums, citrus fruits, roses suffer most from spider mites.
2. Scabbards, or false scutes, are small insects from the Hemiptera family. They got their name for the fact that they look as if they were covered from above with a dense protective shell, similar to a shield. Compared to the mite, they are quite large - they can be seen with the naked eye. They lead a sedentary lifestyle. If you try to remove them from the plant, you can feel resistance. The feeling of adhesion of the scabbard to the surface of the sheet is created. They usually concentrate near the veins or on a young shoot.
3. Aphids for indoor plants are not as popular as the previous ones. The reason is simple - these insects are larger, so people notice them faster and take action. However, they are colored to match the color of their food supply, which reduces the likelihood of early detection. Infection with these insects occurs quickly. This is due to their ability to fly. If previous pests move through the soil, then these can fly to new plants.
4. Mealybugs are members of the same family as the scale insects. These worms are not worms at all. In size and lifestyle, they are more like aphids. A person who is not versed in the biology of invertebrates usually does not see the difference between aphids and a scale insect. However, there are some indirect indications. The accumulation of these small white insects creates a white bloom effect, as if the plant was sprinkled with flour.
5. Whiteflies are small white butterflies. They are usually concentrated on the underside of the leaf, since the cover is less hard there.

These butterflies lay their eggs where they feed. Translucent larvae emerge from the eggs, bite into the leaves, move along their surface, leaving a layer of sticky sweet bloom. If the concentration of larvae is high, and the leaves are not processed, then the plaque turns from green to black. This is due to the fact that fungi begin to multiply in a sweet environment.

Remember

Destroy aphids in time otherwise, it will spread throughout the entire area and cause ants and fungal diseases on the roses, and it will become more difficult to get rid of it.
Observe preventive measures after all, it is much easier to protect a rose from aphids than to fight a pest later.
Use folk remedies for small infections, because they are much cheaper, safer and more accessible than chemical ones, and also do not spoil the soil.
Do not use folk remedies for severe infection, since, most often, they are ineffective, and you will simply waste your time.
Observe safety measures when working with chemicals, so as not to get poisoned.

Features of processing indoor roses

Houseplants are difficult to spray with poisonous drugs. The affected specimen is isolated from other cultures. The degree of invasion is carefully studied, the destroyed buds are cut off. Aphids are washed off with soapy water or treated with an insecticide, the rose is hidden under a bag for 12 hours.

The next day, the polyethylene is removed, fertilized with complex fertilizing with potassium and phosphorus. To prevent invasion, it is necessary to spray the bush with an infusion of tobacco dust. The rose is examined for a week, treated with Epin for stress and fungicide for diseases. If the aphid survived, then the poison is changed. Within 30 days, the affected specimen is kept in quarantine.

Aphid control: what does the enemy look like?

Aphids are a very small pear-shaped creature that appears in large numbers on the tips of pink stems in May and early June. Most of them are light green at this time, so they are almost invisible on the stem. The pest can multiply rapidly, suddenly appearing out of nowhere - as if a huge army had carried out an invasion of your garden overnight.

Aphids are very smart. By capturing the plant, it forces the leaves to curl inward to protect itself from being sprayed. If you don't fight it, it attacks delicate young shoots, emerging leaves and even rose twigs.The pest loves juicy young shoots, so we protect, first of all, the shoots of this year. Shoots covered with aphids, look weak, dry, leaves are covered with "rust".

Did you know that ants "take care" of aphids?

Ants love the dark, sticky substance that aphids give off. Therefore, the ants will diligently carry insects to your rose bushes and "graze" there. (It is very interesting to watch ants work, although you may not want to watch too long and start saving your roses.)

If you see ants scurrying up and down the stems of the roses, check for aphids and get rid of both before your flower beds turn into "pastures."

Difficulties in growing hibiscus

Hibiscus is a fairly unpretentious plant, so even if you make a mistake somewhere when leaving, it can be quickly corrected. Those who have just recently acquired a Chinese rose often wonder why the leaves of hibiscus turn yellow, begin to dry out or fall off. This problem can be easily corrected by more frequent spraying as soon as you notice that the leaves have become lethargic. In addition, the plant itself sheds its leaves after flowering - this is completely normal.

If the flower is withered, it could be a sign that the ground is too cold. From hypothermia, the leaves can also turn black. The plant must be returned to a warm place and do not forget about abundant watering. If everything is done on time, hibiscus can still be reanimated.

Why do hibiscus leaves turn yellow and fall off? This problem may indicate poorly filtered water. If the leaves are not only yellow, but also with brown edges, this means that there is little nitrogen in the ground. When the temperature and humidity readings change dramatically, the plant sheds both leaves and buds under stress. However, then it is restored and grows new leaves.

Signs of rose infestation by aphids

The pest settles on the lower tier of greenery and on the back of the foliage, therefore, it is not immediately noticeable to humans. The colony is growing rapidly, assimilating healthy plants. Aphids on a rose can be recognized by symptoms:

Sticky coating. A thin sugary layer covers the shoots, plates.
Yellow markings. In places of bites, the tissue lightens.
Dropped buds. Flowers do not bloom, gradually wither and crumble.
Deformation of branches. The aboveground parts stop developing and mutate.
Lack of gloss. There is no healthy shine on the foliage, the greens look dusty.

Aphids on a Chinese rose are just as dangerous as they are on street views. Pests eat intercellular juice, weaken plants. Cultures lose their decorative effect, in a neglected state they suffer from fungi and infections. Ants feed on the pad, which carry pathogens on their paws.

Output

Aphids are an unpleasant guest in any garden. This insect lives with pleasure on almost all garden crops, including roses. It is simply necessary to drive away aphids, otherwise it will not only prevent the roses from growing and blooming normally, but will also systematically destroy all plantings.

Therefore, you need to deal with aphids immediately, as soon as it became clear that it appeared on the rose bushes. You can give preference to folk methods, you can use professional poisons. In any case, almost all methods have long been tested by gardeners, they have their positive sides and negative qualities.

Care

Temperature
... The Chinese rose is a thermophilic plant. In spring and summer, the temperature will be 25 degrees Celsius, and in winter - 15-20 degrees. If the temperature is below 10 degrees in winter, the leaves will fall off. In the summertime, put the flower on the balcony, protecting it from rain and wind.
Lighting
... Hibiscus is a light-loving culture. For him, diffused light is important. If in the summer direct sunlight falls on the flower, then this is fraught with the development of a burn. Grow the plant on east or west windows.
Watering
... In spring and summer, the Chinese rose needs abundant watering.Use separated water and room temperature. Avoid waterlogging. In winter, watering is moderate. Wait until the soil is completely dry before the next irrigation. It is imperative to provide for high-quality drainage.
Air humidity
... In summer, hibiscus needs high humidity. It is useful for him to carry out frequent spraying. Only the water should not fall on the flowers, otherwise they may fall off. Less moisture is required in winter. But if there is central heating, then spraying should be carried out every other day.
Top dressing
... From spring to autumn, apply complex nutrient compositions intended for flowering indoor plants. Do this every 2 weeks. Beginning in August, reduce nitrogenous fertilizing.
Pruning
... Prune the Chinese rose tightly every spring. This will allow the bush to acquire a compact shape with a large number of buds. If the plant begins to stretch strongly, then cut it off during the growth period. By pruning, the flower can take the form of a shrub or tree.

What to process

The question of how to treat hibiscus for diseases is very relevant in the presence of pests. If the prevention of diseases caused by pests turned out to be ineffective, then the following treatment methods are carried out:

From aphids - treatment of the flower with Anabazine, Nicotine sulfate. It is recommended to change the drug more often - to Decis, Fitoverm, Intra-vir, Tobacco dust. With a single lesion of the leaves of aphids, treatment with a soap solution helps well.
From scabbards - spraying with Actellik solution or other insecticides.
From the worm - processing the leaves with mineral oil, which is done only when the plant is in the shade.
From whitefly - treatment with Aktara, Karbofos, Iskra, Tanrek, Biotlin, Bison, applying potassium soap.
From spider mites - washing the plant with soapy water, treatment with preparations Lightning, Vertimek, Akarin, Fitoverm.
From gall midge - collection of affected buds, preventing them from falling to the soil. The soil itself must be treated with any medicine for soil pests.

Of the folk remedies that can be used to combat plant pests, the following are popular:

Pour dry red pepper with water (1: 2), cook for an hour, strain. 10 gr. dilute the resulting solution in a liter of soapy water, process the plant. This method works well against ticks, aphids.
Dry mustard (50 gr.) Boil in a liter of water for 15 minutes, let cool. Dilute the product in 20 liters of water, rinse the leaves of the flower from aphids, scale insects

If you follow all the conditions for growing a plant, then it is unlikely to have problems in the form of diseases and pest infestation. A healthy hibiscus will bloom for a long time and delight its owner.

There are several diseases that affect different parts of the flower:

Differences from pest damage

Diseases caused by improper care: sunburn

In most cases, the first signs of a deterioration in well-being or a disease of a Chinese rose are any changes in the condition of its leaves, as well as some of the other symptoms listed below. In each case, the plant may not be healthy, usually for one of several reasons. The following are the main symptoms and the most likely causes that caused them.
Yellowed hibiscus leaves

Turned yellow - the plant is infected with pests (spider mites or aphids), its roots turn white, leaf chlorosis or there is not enough humid air in the room.
Turned yellow and fall off - stress (occurs when unfavorable factors arise or a sharp change in conditions of detention), drafts or insufficiently humid air in the room, and in winter also from overmoistening of the roots.
Fall off - there is not enough humid air in the room, stress, a sharp change in the intensity of lighting or drafts.
Fade at the tips - the plant lacks phosphorus and nitrogen, as well as, most likely, some other nutrients.
Curled up into a tube - pest damage, most likely aphids.
They fall together with flower buds - it is too hot in the room, the plant does not have enough potassium, or it is affected by a pest (gall midge).
Wither along with the entire plant - the room is too hot or the humidity is below the critical levels for a Chinese rose.

What exactly is the reason for the appearance of most of these symptoms should begin to be clarified by identifying possible deficiencies in care. That is, we determine whether the temperature and humidity in the room, the frequency and amount of watering, as well as spraying and fertilizing with fertilizers required for hibiscus, correspond. Then, by the method of elimination, we determine the possible, and, most often, the real reasons. If they consist in improper care, then we eliminate the mistakes made. And how to deal with other reasons will be discussed later.

Most of the problems that have arisen with hibiscus are solved by bringing the conditions of its maintenance back to normal and eliminating errors in care. Since the purpose of this article is not to consider exactly how to care for a Chinese rose, all these points will be omitted. Let us dwell only on the elimination of a number of specific omissions in the care indicated above in the chapter on the main symptoms of a deterioration in the condition of the plant.

Fertilizers for Chinese rose

When a plant lacks some nutrients, then, of course, it is necessary to feed it with appropriate preparations, including precisely the missing elements. If the roots become waterlogged in winter, then watering should be temporarily reduced in quantity and volume, and the plant itself should be sprayed instead, making sure, again, that less water gets into the soil and it does not turn into a liquid slurry. What to do in the event of drafts is clear and so - you need to eliminate the cause of their occurrence or move the Chinese rose to another, quieter place.

Now about the treatment of diseases. Non-infectious chlorosis can not only be defeated, but also prevented by regular feeding of Hibiscus with fertilizers. If, nevertheless, this misfortune happened, the emphasis should be made on those dressings that contain the missing elements. It should also be noted that the symptoms of iron deficiency (yellowing of leaves) appear against the background of a lack of nitrogen and an increased content of chlorine and calcium in the water used for irrigation.

Infectious chlorosis is best prevented. For this, contact of the Chinese rose with diseased plants should not be allowed, it is necessary to make timely transplantation and fertilization to it, and it is also necessary to regularly clean it of dust and dirt. The latter is best done with my hibiscus in the shower. At the same time, cover the soil in the pot with cellophane.

And yet, all new plants brought home must undergo a temporary quarantine procedure. That is, for several weeks they must be placed separately and away from the existing flowers. In case of a hibiscus disease, use the appropriate drugs (designed to combat identified diseases and pests) for its treatment.

To prevent sunburn, Chinese roses grown in greenhouses and grown in a darkened room must be accustomed to changing lighting gradually, putting them out in the sun, first for an hour and a half a day. Then we gradually increase the duration of the plants' stay in bright light and only after full adaptation to it we change their "place of residence".

Zircon for rose treatment

We cut off all the affected (dried) fragments of the plant, while capturing its healthy parts a little.
We treat the whole rose with special antifungal compounds: Fundazol, Topsin, Dezavid, Alirin-R or others. You can also use the drug Rovral, the solution of which must be poured at the root. There is also a folk remedy - spraying the plant with Trichopolum solution (2 tablets per 1 liter of water).
Additionally, you can stimulate the protective mechanisms of the rose by treating it with Epin, Zircon, Domotsvet. Just before that, you need to make sure that the selected composition can be used in combination with the antifungal agent used.

If at the initial stage it was not possible to cure vascular wilting, and the hibiscus continues to hurt and wither, it will have to be destroyed. Bacterial spotting is remarkably cured by spraying the plant itself while watering the soil in a pot with a solution of Trichopolum (1 tablet for 2 liters of water). Also effective are such well-known copper-containing preparations as copper sulfate and Bordeaux mixture.

When a plant is stressed, the first step is to try to figure out what caused it. If the reason is the onset of a strong deviation of the conditions of detention from those necessary for the hibiscus, then it must be eliminated. The plant is unlikely to adapt to this, especially if the changes that have come are, in principle, unacceptable for its life. Stress can also occur due to the fact that the rose is greatly disturbed, for example, it often changes its "place of residence" (constantly transplanted or transferred from one place to another, which usually happens during repairs and moving) or does not monitor the behavior of children and pets that are overly curious about houseplants.

Signs of stress in hibiscus

Such effects on the plant must also be stopped immediately. In the first case, the hibiscus should, at least for a while, be left alone until it cope with stress (stop transplanting or choose the most suitable place for it, from which it will not need to be transferred for a relatively long time). In the second - to forever protect the plant from domestic "robbers", that is, for example, to find a place inaccessible to them.

Stress can also be caused by minor changes in conditions of detention, when their main parameters are within acceptable values (associated with: transfer from one room to another or from a greenhouse to a permanent habitat; with small deviations from previous care), seasonal changes in the environment. environment (for example, a decrease in the level and duration of lighting in winter), any damage, transplantation or flowering (also a stress load for young and weakened plants). In this case, no drastic measures will have to be taken.

Well, with the stress itself, the Chinese rose, as a rule, is able to cope on its own. In the first two cases, this will happen after the elimination of the reasons that provoked it, and in the last - due to adaptation to new conditions. But in order for the plant to successfully and quickly cope with stress, it is necessary for it to provide rest, spray more often and more closely monitor compliance with the schedule and norms of watering and feeding, as well as the quality of water and fertilizers used for this.

In addition, hibiscus can be helped to stimulate the adaptive processes in it with the help of anti-stress drugs, especially if the stress state does not go away for a long time and the plant is severely weakened. These include: Zircon, Fitosporin, Planriz, Epin-Extra, Planriz, Kresacin. Such drugs have an immunostimulating and anti-stress effect on plants. It is necessary to choose and use the necessary "drug" in accordance with the instructions for it.

Pests start on a plant in two cases: when they are transplanted into contaminated soil, or as a result of contact with already diseased flowers. Hibiscus is most commonly affected by the following pests.

Aphid. This small insect settles primarily on young leaves and shoots, as well as on plant buds. It multiplies very quickly, creating whole colonies.Able to completely destroy unopened flowers and young leaves, which at the initial stage of the lesion become sticky and deformed. It is necessary to fight aphids by treating the plant with Akarin, Fitoverm, Biotlin, Intra-Vir, Decis.

Optimal temperature conditions

How to care for hibiscus? The Chinese rose loves warmth, therefore, for its comfortable existence, it is necessary to maintain the temperature not lower than 18 and not higher than 22 degrees Celsius. However, hibiscus blooms during the cool period at + 15 ° C.

Therefore, after the summer months, it is better to take the flower to a cooler place without bright sunlight. In summer, the pot with the plant can be kept on the veranda in the garden or on the balcony of a city apartment. The Chinese rose loves fresh air, but it should be protected from drafts.
