1, reduce watering
Evergreen has a certain drought tolerance and is not resistant to waterlogging. If it is watered too much during the maintenance period, it will hinder the breathing of roots and lead to yellowing and drooping leaves. At this time, it is necessary to stop watering, strengthen ventilation and evaporate excess water.
2. Keep out strong light
If evergreen is often placed in direct light, it is easy to sunburn the plants, resulting in drooping yellow leaves. At this time, cover evergreen with a hood immediately to prevent strong light exposure.
3. Reasonable temperature control
Evergreen is a positive plant with poor cold tolerance. If the temperature control measures are not taken in time after winter, the plants will be in a low temperature environment for a long time, and the leaves will be frostbitten and drooping. At this time, Evergreen should be moved back to a warm place indoors immediately.
4. Supplement nitrogen fertilizer
Evergreen consumes a lot of nutrients during its growth period. If the plants are not fertilized for a long time, the soil will be barren and the roots will not supply nutrients to the leaves, and the leaves will turn yellow and droop. At this time, liquid fertilizer based on nitrogen fertilizer should be applied to Evergreen immediately.
