It is almost impossible to prevent the appearance of a spider mite. It is a lot in the autumn-winter period, when the rooms are dry air. The simplest measure of fighting this pest will be a constant spraying of water on the plant. This parasite does not like high humidity. If it does appear, try washing the plant with warm water and soap. But soap should not contain oxidizing agents.

To completely exterminate the spider mite, special chemical preparations must be used, which can be bought in garden centers. Another method of killing a mite is to rub the leaves with 96% alcohol.

Powdery mildew

This is a scourge of roses. Every gardener at least once met with this opponent. The cause of the appearance of white plaque is the fungus Spheroteca pannosa.

The affected plant should be washed with a solution of soda: 2 teaspoons of soda per 1 liter of water, or pollinated with ground sulfur. When treating with soda, then continue to treat only with the same soda. When processing the plant, you must first close the earth in a pot. Leaves of a large bush carefully diluted with a solution of soda, and small bushes rinse well after completely immersing them in a container with a solution. Treatment of the plant is carried out until the disease completely disappears with an interval of two weeks. When yellowing and falling leaves during the treatment do not need to panic. This is a natural phenomenon: leaves eaten by powdery mildew should fall off. Do not be afraid, because in the axils of the leaves of the rose there are alive buds, from which later new leaves will appear.

The second method of combating flower pests, may be the pollination of roses in gray. This treatment should be carried out at + 18 ° C. To do this, the sick roses are placed in a small glasshouse with glass frames. The earth in the pot and the space between them are covered with wet rags. After that, the flowers are well watered and sprinkled with clean water. The plants themselves are powdered with ground sulfur, as well as wet rags and the inside of the frames of the greenhouse. Two-time processing by this method can be quite enough. The interval between sulfur pollination should be at least 10 days.
