Is it OK to trim a tree in the fall?

Avoid pruning in fall. Pruning cuts can stimulate new growth that, unfortunately, will be killed as temperatures drop to freezing. Trees and shrubs reduce their energy production as the growing season ends, so new growth in autumn will use a plant's stored energy reserves.

Is it better to trim trees in the summer or the fall?

How do you keep oak trees healthy?

Water deeply, to one to two feet, in the outer two-thirds of the root zone. Alternatively, placing organic mulch under the tree can conserve moisture in the root zone by reducing surface evaporation. Mulch also inhibits the growth of weeds, which can compete with oak roots for moisture and nutrients.
