Is now a good time to trim your trees? It depends on the species — and right now, timing really matters.
We just published a full seasonal pruning guide for Lake & Cook County homeowners. Here's what's happening this week:
✅ Do NOW: Prune crabapples, cherries & redbuds right after bloom — your window is open today.
✅ Safe anytime: Remove deadwood from any tree.
⛔ Hold off on oaks & elms: Oak Wilt is at peak risk May through July. No structural cuts until December.
The wrong cut at the wrong time can kill a mature oak within weeks. The right cut today keeps your trees healthier and safer for years.
Our ISA-certified arborists serve Lincolnshire, Vernon Hills, Lake Forest, Libertyville, Buffalo Grove, Highland Park & throughout Lake and Cook Counties.
