1. Reasonable wateringCause: Excessive watering. Because the roots of Magnolia plants are fleshy roots, if the soil in the pot is waterlogged, the roots will rot and the leaves will turn yellow. Solution: Reduce the amount of watering and place it in a ventilated place. 2. Proper lightingReason: Insufficient light can also cause old leaves to turn yellow. Solution: When there is insufficient light, we put it in an environment with sufficient sunlight, and the situation will improve. 3. Irrigation and soil fillingReason: Excessive fertilization can also cause the leaves of white jasmine to turn yellow. Solution: After fertilizer damage occurs, we can control the yellowing leaves by watering, pouring soil, or even changing pots to reduce the fertilizer content in the potting soil. 4. Change soil and apply fertilizerReason: If repotting and topdressing are not done for a long time, the soil in the pot will be too poor and the leaves of the white jasmine will turn yellow. Solution: In this case, we can see obvious changes in the leaves by changing the soil and applying fertilizer. 5. Improve soil environmentCause: Another situation in which white jasmine leaves turn yellow is particularly prone to occur in the north, that is, in an environment of alkaline soil and alkaline water, its leaves will develop yellowing disease. Solution: In this case, we can improve the soil and apply acidic fertilizers. By adding vinegar or alum fertilizer to the water during watering, the acidic environment of the white jasmine will be improved. |
