This is the storm performer of the group — arborists rate its limb attachment and wood strength as good under ice and snow, and it comes through Indiana glaze events with far less breakage than maple, pear or basswood on the same street. The qualifier is mass: those limbs are heavy and few, so the rare failure (usually at a preexisting bad union or on a previously topped tree) drops a lot of weight in one piece.
Prune in late dormancy, and prune it young. The trap is that coffeetree has extremely coarse, sparse branching with no fine twigs to hide a mistake — a bad cut is visible for a decade because the tree does not backbud freely to fill the gap — and the narrow, upright cultivars sold for street use build codominant unions that need to be corrected at 3 to 5 inch caliper, not at 15.
