What happens when trees are defoliated?

Trees defoliated more than 40% use next year’s energy reserves to grow new leaves.  Healthy trees may withstand several years of defoliation stress.   Trees with other stress factors such as drought, disease or poor growing conditions could die sooner.  Ever- greens are unable to replace their needles and may die when defoliated.  Keep trees watered and fertilized to lessen any damage.
