Rarely a serious problem. Look-alikes: Jumping oak gall, tubakia leaf spot, oak leaf blister, other fungal leaf spots. Jumping oak gall Brown leaves appear on trees in the white oak group in late spring. Severe infections may cause the leaves to turn black, curl up and fall. On the underside are brown galls with the larva of a small wasp inside.
Why do leaves fall from trees in fall--and can they keep hanging on? Researchers say that they have pinpointed chemical signals that cause leaves, flowers, and fruit to fall from plants â and that, if blocked, might allow them to hang on forever. Scientists already knew there were cells in the tissue linking stems and branches that release chemicals that break down plant cells, causing leaves, et al, to fall off.
