Today's sharing: How to deal with Kalanchoe black rot and the small green plant maintenance experience of remedial measures after Kalanchoe black rot, next, the editor will introduce to everyone.
Kalanchoe, belonging to the genus Narcissus of the Liliaceae family, is a plant native to the Iberian Peninsula and is an ornamental plant. When infected with diseases and pests, including brown spot disease and leaf blight, it can cause the leaves of the plant to turn yellow, reducing its ornamental value, and may even lead to the death of the plant. Next, let's talk about what to do if Kalanchoe has black rot.
1. Prevention before planting
Before cutting or transplanting, soak the roots in a carbendazim solution to disinfect and kill some potential pathogens. You can also use the solution to wash the pot, which can kill some potential pathogens in the pot and roots.
2. Change the soil
Since the culprit causing black rot is a fungus that is very persistent, it is best to change the potting soil directly after the plant is infected, replacing it with loose, breathable, fertile, and well-draining slightly acidic sandy soil. If the soil is not changed for a long time, it can lead to soil compaction and trigger black rot, so to prevent soil compaction, it is necessary to loosen the soil regularly.
3. Water control
Excessive watering is also one of the causes of black rot in plants. If excessive watering leads to waterlogging in the pot, it can cause the roots to rot due to difficulty in breathing. Therefore, it is necessary to reduce the watering frequency and amount, following the principle of watering when dry and not watering when not dry, and watering thoroughly when watering.
4. Ventilation
Kalanchoe prefers a warm environment, and both high temperature and high humidity can cause black rot. Therefore, special attention should be paid to the ventilation of the breeding environment, especially during the rainy season, when drainage should be paid attention to. Also, it should be allowed to receive some sunlight, but not directly exposed to the sun.
5. Pruning
When the plant is not severely ill, it can be immediately taken out of the pot, and the rotting roots and branches should be cut off. If they cannot be cut off, some carbendazim solution can be applied to the affected area, and then the pot and soil should be changed. If the black rot is very severe, it can be abandoned for treatment, and healthy branches can be cut for propagation through cutting.
