There are yellow spots on the leaves of Milan. Why are the leaves of Milan turning yellow?

1. Strong sunlight exposure

Milan is a light-loving plant. Although it likes light, it is afraid of excessive sunlight. Especially in summer, direct sunlight can easily cause yellow spots on the leaves, so appropriate shade should be provided. Usually the plant should be placed in semi-shade to allow it to receive scattered light, but it can be exposed to the sun every morning and evening. In addition, you can also install a shading net to reduce the harm of direct light.

2. Unsuitable soil

Milan, like most plants, likes loose and fertile soil. If the soil hardens and compacts, it will easily affect the breathing of the roots and hinder the penetration of water, which is not conducive to the growth of the plant and causes the leaves to turn yellow. In this case, it is necessary to replace the potting soil in time, loosen the soil appropriately, take out the plant, replace it with new soil and replant it.

3. Excessive water and fertilizer

Milan needs sufficient water and fertilizer during its growth, but excessive water and fertilizer will affect its development, causing root rot and yellow leaves. In daily maintenance, you must control the amount of water and fertilizer, ensure that the soil in the pot is moist but not wet, and dilute the fertilizer before applying. If the roots have rotted, you need to remove the plant from the pot, trim it, and then plant it in new soil.

4. Infestation by pests and diseases

The leaves of Milan will turn yellow after being attacked by diseases and insect pests. For various diseases, it is often necessary to prune first, cutting off the diseased branches and leaves to prevent infection and recurrence. In addition, spraying of pesticides is also required. For pests, in addition to manual capture or using their phototaxis to lure and kill them, they can also be controlled by spraying pesticides.
