Water appropriatelyReason: The yellowing of magnolia leaves may be due to excessive water accumulation in the soil, which leads to root rot and yellowing of leaves, and the number of yellow leaves is relatively large. Solution: Find a way to drain the stagnant water in the soil in time, and improve the water and soil to increase soil aeration. If the condition is not very serious, you can water the magnolia with rooting agent to encourage it to grow new roots. If the condition is serious, you need to dig it out and replant it, trim off the rotten roots and apply growth hormone and rooting agent to stimulate it to sprout again. 2. Prevention and control of pests and diseasesReason: The yellowing of its leaves can also be caused by pests and diseases, such as scabies or aphids' sucking and the occurrence of sooty mold can cause yellowing of leaves. The amount of yellowing is small and more concentrated. Solution: Pests and diseases should be controlled, and the yellowing leaves phenomenon can be controlled by taking appropriate measures. 3. Leaf agingThe yellowing of magnolia leaves may also be caused by normal aging of the leaves and the low temperatures in autumn. This is a normal condition and no action is needed to deal with it.
