Norway maple, red maple and sugar maple are the species most commonly affected. The trouble often starts after insect-induced defoliation, which weakens the trees and makes them more susceptible to secondary pathogens. Early signs of decline include small or scorched foliage, and premature fall colors on some of a tree's branches.

Several trees normally have marcescent leaves such as oak (Quercus), [5] beech (Fagus) and hornbeam (Carpinus), or marcescent stipules as in some but not all species of willows . [6] All oak trees may display foliage marcescence, even species that are known to fully drop leaves when the tree is mature. [7]
If a large tree is unable to produce enough sugars to feed the roots, it will slowly die from starvation. [4] Some people have been known to top trees in order to stimulate new growth. When a tree is topped, many adventitious shoots, known as suckers begin to grow from the wound. This is the tree's response to the sudden loss of leaves.
Many pine trees turn yellow this time of year because of normal “needle drop” on the inside branches
