Defoliation is the process of removal of leaves from a tree other than natural leaf fall. It could be done by a defoliant which could be any chemical sprayed on trees to fall off its leaves.
Neem ( Margosa tree) is not evergreen plant. Defoliation takes place in this plant during spring season.
There are several reasons your copper beech tree may not have leaves. It could be due to environmental stressors such as drought, excessive water, or temperature fluctuations. Additionally, pest infestations or diseases can cause defoliation. If the tree is young or newly planted, it might still be adjusting to its environment.

When a fungus attacks an ash, dogwood, maple, oak, sycamore, or walnut tree, it defoliates and disfigures the tree, significantly diminishing its appearance. During the spring, watch for twig cankers, twig dieback, defoliation, and leaf blotching. Use fertilization and fungicide applications as needed during the spring, and remove and rack the dead leaves in the fall.

As gypsy moth populations defoliate trees, they initially thrive due to increased food availability, leading to population growth. However, extensive defoliation can weaken or kill host trees, ultimately reducing available habitat and food sources for the moths. This can result in a population decline over time as the ecological balance shifts and resources become scarce. Additionally, the decline of host trees can promote the growth of other species that may not support gypsy moth populations.

The brown tail moth primarily damages hardwood trees, particularly oak, apple, and cherry trees. The larvae feed on the leaves, leading to defoliation and weakening of the tree, which can make it more susceptible to other pests and diseases. Severe infestations can result in significant stress and potential death of the affected trees if not managed properly.
