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 ventilation of the soil. If it is caused by diseases and pests, it is necessary to apply the right medicine for timely treatment. If it is caused by too much sunlight, the plant should be moved to a shaded area. Next, let's talk about the solutions for yellowing magnolia leaves in detail.
1. Replace Potting Soil
Magnolia trees have high requirements for soil. It is best to choose sandy soil with good drainage and slightly acidic properties for planting. If the chosen soil causes root rot, it can lead to yellowing leaves. It is necessary to replace the potting soil promptly, disinfect the roots before repotting, and cut off the rotten roots before repotting.
2. Shading Treatment
Magnolia trees like sunlight but avoid direct strong sunlight, as it can cause excessive evaporation of water from the branches and leaves. You can first cut off the yellow leaves and move the plant to a shaded area for maintenance. Once the plant has gradually recovered, move it to a soft light area for maintenance.
3. Appropriate Watering
Magnolia trees like moisture. If the potting soil is too dry, it can affect the photosynthesis of the leaves and easily lead to withered branches and leaves. It is necessary to water promptly and keep the potting soil moist. If the yellowing of the leaves is caused by excessive watering, it is necessary to drain the water promptly. You can promote new root growth by watering with a root stimulant.
4. Increase Fertilization
Magnolia trees like fertilizer. If there is insufficient fertilization, it can lead to poor nutrition of the plant. Fertilization should be done promptly after the plant is potted. Fertilization during the flowering period mainly focuses on compound fertilizers, and nitrogen fertilizers can be applied after flowering. Phosphorus and potassium fertilizers can be applied appropriately during the high summer temperatures.
5. Disease Prevention
Common diseases in white magnolia include yellow leaf disease and anthracnose. It is necessary to cut off 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.
