May 05, One of the most recurring causes of leaf drop is powdery mildew. Many varieties of plants can get this fungal infection, which cause leaves to get a white coating and eventually suffocate and die.

Leaves fall- or are pushed- off trees so that the tree can survive the winter and grow new leaves in the spring. You may ask, Why do some trees lose their leaves before others?
