There are many reasons for the yellowing of magnolia leaves. If it is caused by excessive watering, it is necessary to drain the water promptly and increase the aeration of the soil. If it is caused by diseases and pests, it is necessary to apply the right medicine and treat promptly. If it is caused by too much sunlight, the plant should be moved to a shaded area. Let's talk about the solutions for the yellowing of magnolia leaves in detail.
1. Change Potting Soil
Magnolias require well-drained, slightly acidic sandy soil for planting. If the chosen soil causes root rot, it can lead to yellowing of the plant's leaves. It is necessary to change the potting soil promptly, disinfect the roots before repotting, and剪除 rotten roots before repotting.
2. Shading Treatment
Magnolias enjoy light but should not be exposed to strong sunlight, as this can cause excessive evaporation of water from the branches and leaves. You can first剪除 the yellow leaves and move the plant to a shaded area for maintenance. Once the plant has gradually recovered, move it to an area with soft light for maintenance.
3. Appropriate Watering
Magnolias enjoy moisture. If the potting soil is too dry, it can affect the photosynthesis of the leaves and easily cause the branches and leaves to turn yellow. It is necessary to water promptly to keep the potting soil moist. If yellowing is caused by excessive watering, it is necessary to drain the water promptly, and you can promote the growth of new roots by watering with a root stimulant.
4. Increase Fertilization
Magnolias enjoy fertilizer. If there is too little fertilizer, it can lead to malnutrition in the plant. Fertilization should be done promptly after the plant is potted. Fertilization during the flowering period mainly focuses on compound fertilizers, and after flowering, nitrogen fertilizers can be applied. In the hot summer, phosphorus and potassium fertilizers can be applied appropriately.
5. Disease Prevention
Common diseases in white magnolias include yellow leaf disease and anthracnose. It is necessary to剪除 the diseased roots promptly to prevent the virus from further invading the plant. This can be protected by spraying a solution of ferrous sulfate.
6. Precautions
There is also a situation where the yellowing of magnolia leaves is caused by normal aging of the leaves, which is a normal phenomenon and requires no treatment.
