1. Reduce the amount and frequency of wateringReason: If you water too much, water will accumulate in the potting soil, causing the roots of the osmanthus to rot and the leaves to fall. Solution: Reduce the amount and frequency of watering, and strictly follow the principle of watering when the soil is dry and watering when it is wet. 2. Gradually increase the amount of wateringReason: If you water too little, the soil will dry out, and the number of the plant's capillary roots and absorbing roots will decrease, resulting in insufficient water absorption, causing the osmanthus to drop leaves. Solution: Place the osmanthus in a cool place, then spray it with water more often, and gradually increase the amount of watering until the leaves of the osmanthus return to normal. 3. Spray water on plants and the groundCause: Because the air environment is too dry, the leaves lose too much water, causing them to turn yellow and fall off. Solution: Spray more water on the plants and the ground to make the surrounding humidity reach a certain level. |
