The reason for the loss of leaves of rainbow jade

Rainbow jade is actually very easy to raise succulent plants, as long as it is cultivated according to its habits, there will be no big problem. Rainbow jade is a plant that likes warmth and light, especially the environment with large temperature difference. So to less water more sun, more sun does not mean exposure, exposure will also have problems, less water also depends on the situation, less water in winter, more water in summer, maintain ventilation. So, if your rainbow jade loses its leaves and only grows roots, it may be the following reasons.

1. Watering: rainbow jade grows slowly and is resistant to drought, so it is not suitable for big fat and big water. if you keep watering, it will definitely lose leaves and rotten roots.

2. Light: rainbow jade likes warmth, and he should be fully exposed to light throughout the growing period. But summer exposure can cause sunburn of leaves.

3. Ventilation: the disease of rainbow jade is less, but if the ventilation is not good, the air humidity is high, stem rot and leaf spot will occur occasionally.

How to raise rainbow jade

1. Warm environment with obvious temperature difference between day and night. It has strong adaptability to temperature and can grow well between 10 ℃ and 28 ℃.

2. In autumn and winter, the air temperature decreases, the light increases, and the fleshy leaves gradually turn red, so artificial cooling in the process of cultivation can improve the ornamental value.

3. The room temperature should not be lower than 5 ℃ in winter. Eardrop grass delights in the light, and it should be fully seen throughout the growing season. But summer exposure will cause leaves sunburn, can be appropriate shading or half-sun, noon should avoid direct sunlight. Euphorbia angustifolia grows slowly and is resistant to drought, so it is not suitable for heavy water, dry watering and thorough watering should be seen, while the amount of water and times should be reduced when the room temperature is low in winter. Organic liquid fertilizer is usually applied once a month.

4. Keep good ventilation in summer. Euphorbia angustifolia grows slowly, and the plant shape begins to be scattered after 3 years of cultivation, so it should be pruned in advance.

Disease control of rainbow jade

Rainbow jade has few diseases, and leaf spot and stem rot occur occasionally. Leaf spot is mainly caused by poor ventilation and high air humidity. Internal absorption fungicides can be used for prevention and control. Improving ventilation is the key to prevent leaf spot disease. Stem rot is mostly caused by excessive humidity in winter. The healthy stem segment of the upper part of the plant should be cut for propagation, while avoiding excessive and frequent watering in winter and keeping the basin soil slightly dry.

The harm to Hongzhiyu is mainly leaf spot disease and stem rot, which is mainly caused by poor ventilation and careless watering. 50% carbendazim wettable powder 1000 times solution and 50% methyl thiophanate wettable powder 2000 times solution can be used to control leaf spot disease. When stem rot disease occurs, 70% thiophanate 1000 times solution can be used to smear the disease spot or branches, or thiram 1000 times solution, the effect is good.
