1. Adjust fertilizationReason: During the growth stage of Begonia, if there are fewer leaves, the branches and leaves grow slowly, and the plant is short, it may be due to lack of fertilizer and insufficient nutrients resulting in a small number of leaves. It is also possible that too much fertilizer is applied and it is too concentrated, which will cause the roots to be burned, resulting in not many leaves falling. Measures: If there is a lack of fertilizer, you can add fertilizer gradually to ensure that nutrients are supplied sufficiently. If there is too much fertilizer, you can dilute it with water to reduce the concentration of fertilizer. 2. Adjust the water contentReason: A certain amount of water is needed during the growth period. If there is a lack of water all the time, the soil in the pot will become dry, making it difficult to absorb water. The plant will dry up due to long-term lack of water, causing the leaves to fall off, and there will not be many leaves left. Too much water can cause root burn, which can cause the leaves to wither. Measures: If there is a lack of water in the potting soil, add water appropriately to ensure that there is sufficient water supply. If there is too much water, you can loosen the soil in time and place it in a well-ventilated place. 3. Increase or decrease lightReason: Too much light can cause burns, causing the leaves to dry up and fall off. If there is a lack of sunlight for a long time, nutrients will be difficult to synthesize and the number of leaves will naturally decrease. Measures: Provide correct lighting. If the sunlight is too weak, increase the light appropriately. If the light is too strong, block it in time. |
