1. Proper shadingReason: If the asparagus fern is placed under strong light for a long time during maintenance, the plant will be sunburned, and the leaves will easily turn yellow. Treatment method: Move it away from strong light in time, place it in a place with bright scattered light, or use a sunshade to block part of the sunlight. 2. Control water and loosen soilReason: It is suitable for growing in a humid environment, but if the amount of water is too much, the soil in the pot is always in a state of water accumulation, the roots are irritated and damaged, and the leaves will turn yellow. Treatment method: Control the amount of watering and turn the soil to increase soil drainage and speed up the evaporation of water in the pot. You need to control the amount of water you give it, and just water it thoroughly each time. 3. Proper ventilationReason: Plants also need to absorb fresh air to grow. If the maintenance environment is too stuffy and not ventilated, it will hinder the normal breathing of the plant and the leaves will naturally turn yellow. Treatment method: If you grow it indoors, you need to open the doors and windows more often, but in winter you need to be careful to avoid opening the windows in the morning and evening, as the cold wind can easily freeze the plants. |
