Although hibiscus is quite unpretentious, this does not prevent some pests and diseases from annoying it from hour to hour. Some gardeners sometimes notice how a seemingly well-groomed Chinese rose can change: the leaves turn yellow and it is not known why. I would like to find out this reason, find out what to do, how to protect the plant.

Hibiscus care

Often, hibiscus diseases can cause improper care of it. This reason is the most common. Even damage by pests and fungi can cause less significant damage to the flower than the owner himself.

For a comfortable life, a Chinese rose requires a certain condition. A home flower should be installed near the window, in the brightest place. In the shade, the rose will refuse to bloom. In warm weather, for a rose, you need to open a window for a full flow of fresh air. However, all other windows are closed so that the plant does not end up in a draft.

Why do the leaves turn yellow?

It is better to water the indoor rosebush with warm water and not earlier than the soil dries out a couple of centimeters. Hibiscus needs high humidity. In the summer heat, it should be sprayed. It should be noted that when the winter is very cold, the air humidity and its quality in the room drop sharply due to the increased work of the heating system. During this period, the Chinese rose needs spraying and systematic airing.

Do not forget to feed the hibiscus with complex fertilizers from spring to early autumn. In winter, no feeding is carried out. Exceptions are cases when a rose, brought into the house for the winter, begins to form a flower bud. In this case, fertilization is allowed, but in small doses.

Note: Like all garden roses, indoor roses also need pruning. The best period for the procedure is spring.

What yellow leaves are signaling

What to do if the leaves of a rose turn white

The yellowness of hibiscus leaves, depending on the form of manifestation, indicates a possible cause that caused it:

  • Massive yellowing indicates a possible defeat by aphids or mites. The plant may have chlorosis, or simply the air is not humid enough.
  • Falling yellow leaves are caused by waterlogged roots, stress, drafts.
  • A Chinese rose can shed a yellow leaf from a change in lighting intensity.
  • If the leaf begins to curl into a tube, it means that aphids have settled on it.
  • The leaf withers at the tip - a lack of nitrogen, phosphorus.
  • The foliage falls off along with the bud from a lack of potassium, from the heat, and when the midge is affected by Galitsa.

Attention! The simultaneous yellowing of foliage and its massive fall are caused by root disease from waterlogging, low air humidity and the resulting stress at the same time.

Chinese rose treatment

Why do the leaves of a garden rose fall

Timely measures can help hibiscus to cope with diseases and parasites:

  • Shields. Spraying the plant with Aktellik will get rid of parasites.
  • Aphid. It will help to destroy the Fitoverm pest.
  • Spider mite. Noticing an insect on a rose, you need to rinse the leaves with laundry soap.

Some flower lovers reject the use of chemicals: why use them when you can use proven folk methods. To eliminate parasites, they successfully use infusions of onions, tobacco, and garlic.

After insisting 5 days one of the plants on the water, the resulting liquid is wiped on the trunk, branches and foliage of the rose.

Vascular wilting

This disease is quite serious and difficult to treat. The necrosis from the branches passes to the trunk, gradually covering the entire bush. The diseased plant almost always dies. You need to take care of the plant with vascular wilting like this:

  • When cutting off the affected fragments, the healthy part is also captured.
  • The plant is completely treated with an antifungal composition, Rovral's solution is poured under the root. Also, the rose is sprayed with Trichopolum solution.

Important! When the treatment of the initial stage has not brought results, the rose is disposed of.

Additional stimulation is carried out with the preparations Domotsvet, Zircon, Epin.

Disease prevention

It is much easier to prevent certain diseases by taking some measures than to cure later, fearing to lose the entire plant.

Burn

So, sunburn is prevented by the gradual accustoming of greenhouse and indoor flowers to sunlight. They start with a short time, then increase it. The rose is transferred to a permanent sunny place after full adaptation. In the event that the burn could not be prevented, do not panic - having dropped the damaged foliage, the hibiscus will soon grow a new one.

Leaf burns

Chlorosis

It is quite easy to prevent this unpleasant disease. The non-infectious form arises from a lack of iron, therefore, watering the plant with only settled water, a couple of drops of iron chelate are added to it. The feed should contain sufficient nitrogen.

It is better to prevent the infectious form immediately:

  • Exclude contact with infected plants;
  • When washing hibiscus, the soil of the flowerpot is covered with a film;
  • The plant needs regular transplantation and sufficient fertilization;
  • All new plants must be quarantined.

Council. If viral chlorosis has struck a rose, then treatment is pointless. It should be removed immediately to prevent the spread of infection.

Florist tips

To avoid the appearance of yellow leaves in a Chinese rose, you need to use a little tips:

  • Watering is moderate;
  • Treat foliage with special means;
  • Do not forget about feeding;
  • Limit the abundance of sunlight.

On a note. It is sometimes useful, especially before flowering, to pamper the rose with a sugar solution. An excellent result is obtained by feeding hibiscus with activated carbon.

Finding the problem in time, understanding its cause and taking the necessary measures, you can save your favorite plant. Well-coordinated actions and good advice will allow you to enjoy the wondrous beauty of the Chinese rose for a long time.
