For most tree species, tree trimming in the spring can yield good results. Although the sap is rising in the tree during this time period, early spring allows for easy identification of problematic branches before the tree has fully leafed out. In addition to exposing problem areas, spring tree trimming makes it easy to see which branches are dead and subject to removal.

Pruning during the spring (post-dormancy) and fall (pre-dormancy) is generally the least desirable time as the plant is most vulnerable during those times. Berries and tree fruits are pruned November until bloom; prune blooming ornamentals during and immediately after stumpmulching.barted Reading Time: 8 mins.

Open cuts can leave your tree vulnerable, which may lead to months of struggling. Pruning is also a way to encourage growth.

Sep 04, Once you’ve gotten your hydrangea tree back into a more winter-resistant shape, start pruning early in the spring rather than the fall. That’s because the dried flower heads of the panicled hydrangea have ornamental value over the winter, so you’ll want to keep them until spring.
