Planting & Care

Select a location with well-draining soil and ample space—ideally at least 25 feet from buildings and neighboring trees. Dig a planting hole twice as wide as the root ball but no deeper, then position the tree so the root crown sits level with the ground surface. Water deeply each week for the first growing season to establish roots. Once mature, this elm needs supplemental water only during extended drought periods. Prune in late winter or early spring, removing damaged branches and thinning the canopy to improve air circulation and shape. Apply balanced fertilizer in early spring only if growth appears sluggish or foliage looks pale.
