What causes yellow spots on the leaves of plants that are growing well?
Many different things can be responsible for yellow spots. These include poor culture as well as mysterious causes we know nothing about. If only a few leaves are spotted, the plant will not be harmed, but if the leafspot is general, then the plant may die. Pick off spotted leaves and destroy them. Be careful not to overwater or splash leaves. Check the room temperature to be sure it is not too hot for good plant health.
