Every fact cited
Late winter dormant-season pruning is the default recommendation for most Sioux Falls shade trees. Oaks are the exception: avoid pruning between April and July, when oak wilt-spreading beetles are most active. Flowering trees pruned right after they bloom, rather than in winter, keep next year’s flower buds intact.
Frequently Asked
01
Why shouldn't I prune oaks in the summer?
Fresh pruning wounds on oaks during the April–July window can attract sap beetles that carry oak wilt fungus from infected trees — pruning outside that window significantly reduces the risk.
