Countermeasures for the reasons why Euphorbia leaves dry up in winter Euphorbia, as one of the common plants in our country, is loved by many horticultural enthusiasts for its unique ornamental value. In winter, many Euphorbia leaves dry up, which has undoubtedly caused trouble to flower lovers. This article will explain the reasons why Euphorbia leaves dry up in winter and provide corresponding countermeasures. Reasons why the leaves of Euphorbia chinensis dry up in winter 1. Insufficient light: In winter, the sunshine period is short and the light intensity is weakened, which causes Euphorbia chinensis to be unable to carry out adequate photosynthesis, resulting in the phenomenon of dry leaves.
2. The temperature is too low: When the temperature drops in winter, Euphorbia can't adapt to the low temperature environment, causing damage to leaf cells and causing dryness.
3. Insufficient water supply: The temperature in winter is low and soil water evaporates slowly. However, at this time, Euphorbia has a large demand for water, and insufficient water supply will cause the leaves to dry out.
4. Air drying: When the air is dry in winter, the evaporation of water on the surface of Euphorbia leaves accelerates, causing the leaves to dry out. Response measures 1. Increase light: Place Euphorbia in a place with sufficient light and try to receive full sunlight. If conditions are limited, plant growth lights can be used to supplement the light.
2. Appropriate cooling: On the premise of ensuring the growth of Euphorbia euphorbia, appropriately reduce the indoor temperature to adapt it to the low temperature environment.
3. Timely watering: In winter, Euphorbia requires a large amount of water, so the soil should be kept moist. The watering time should be carried out in the morning or evening to avoid watering at high temperatures at noon.
4. Increase air humidity: Use a humidifier or sprayer to increase indoor air humidity and reduce the impact of air drying on Euphorbia leaves.
5. Prevention of pests and diseases: Winter is a period of high incidence of pests and diseases. Regularly inspect Euphorbia to prevent and control pests and diseases found in time.
It is a common phenomenon to dry out leaves of Euphorbia in winter. Understanding the reasons and taking corresponding measures can effectively improve the growth of Euphorbia euphorbia. I hope this article can provide some help to flower lovers.
