Trim forsythia TREE
We have a forsythia tree, not a bush. Would the pruning suggestions also apply to our tree? How about the suckers - remove entirely? Thank you.

Forsythias are actually shrubs, only the "trees" have simply been trained or pruned into a tree form. So, yes, the pruning would be similar. As for sucker growth around the base, these can be safely removed any time without any harm. This is normally the tree's way of trying to revert back to its natural shrub-like form.
