How to prune hackberry bonsai

Late winter for structural work; spring through summer for pinching. During dormancy, shorten or remove branches to refine the tree's architecture, cutting just outside the branch collar. Once growth resumes in spring, pinch new shoots back to 1–2 leaves repeatedly throughout summer to encourage dense, fine ramification across the canopy.

Structural pruning once annually in winter; pinching every 2–3 weeks in season. Hackberry bonsai (Celtis occidentalis) is a fast-growing deciduous species that buds back reliably, making it well suited to regular pruning. Structural work is done in late winter dormancy. Frequent summer pinching builds the fine twiggy ramification characteristic of a good hackberry bonsai silhouette.
