3. Gray rot - sticky leaves with a gray coating, which later turn into porridge. Replace the soil, water regularly, adhere to proper ventilation. Use fugicides and good temperature conditions for treatment.
4. Late blight or late blight - brown spots or brown bloom on the plant. This is due to poor ventilation and excess water in the soil. You need to reduce watering, choose the right fertilizer, carry out preventive procedures and treat the plant with fugicides.

Common pests

• Aphid - The most dangerous enemy of Kalanchoe. Appears mainly in the spring. If no measures are taken at the time, it will spread to neighboring plants. Aphids are small green or black insects that appear on leaves or stems. She takes the juice of the plant and infects it with her poison. Damaged areas are covered with a sticky substance that prevents the plant from breathing.

  At the initial stage, it is difficult to notice infection, since insects are very small and settle on the back of the leaf. You can only detect due to the unhealthy appearance of the plant. It becomes dirty and deformed. To get rid of aphids, you need to trim the affected areas and burn them. Treat the remaining plant with an insecticide. Repeat once a week for a month. You can also use green potash soap: dilute in water and wash the solution with a plant. Can be replaced with laundry soap.

• Multi-claw ticks - small glassy ticks. When it appears, leaves and petioles are covered with brown bark, plant tissues harden and bend. Wash off the insects with a soapy solution and treat the plant with an insecticide.

• Scaffolds and false shields - insects with a two-millimeter body, top coated with wax. They form a plaque (in which a soot fungus forms) and an accumulation of insects on the plant. Leaves turn yellow, fall off, growth slows down, flowering stops. For treatment, immediately remove all insects and wash the plant with soapy water. Before removing insects, treat them with alcohol. You can use folk remedies (wipe the plant with cotton wool with alcohol, use garlic or an old toothbrush).

• Mealybug
- the insect feeds on Kalanchoe juice. It propagates the fungus "black mold". If you do not take action, the plant will die. The appearance is determined by the appearance of white wax discharge. For treatment, use mineral oil to spray the leaves.
