1. Increase the temperatureReason: If the leaves of coleus suddenly wilt in winter, it may be because the temperature is low, causing the roots to be frostbitten. When there is a problem with the root system, the leaves will naturally be affected. Measures: Pay attention to maintaining a good growth temperature and keep it within an appropriate range. In winter, you can move it indoors for maintenance to avoid being attacked by cold winds.2. Pay attention to ventilationReason: If the plant stays in a hot and stuffy place for a long time, its growth will be affected. Without access to fresh air, the leaves will wilt. Measures: Pay attention to ventilation at ordinary times. When the temperature is suitable, you can place it near the window for maintenance to facilitate air circulation.3. Adjust the moistureReason: Improper water application is an important reason for leaf wilting. If no water is given for a long time, the soil in the pot will lack water and the roots will find it difficult to absorb water, which will naturally cause the leaves to wilt over time. If too much water is applied, it will also have an impact, causing water to accumulate in the potting soil, the roots will rot, and the absorption function will be hindered. Measures: Pay attention when watering and adjust the frequency according to growth needs. If you find that you are short of water, replenish it in time. If there is too much water, it needs to be discharged in time. |
