Pruning your shrubs and trees is the horticultural practice which promotes plant health care, vigor, appearance and safety. Pruning and trimming occurs, depending on the plant, typically during the winter and summer months to remove dead or dying limbs. Structural pruning ensures the plant's future viability is preserved. Aesthetic pruning encourages flower and fruit development. Lynch believes in hand-pruning shrubs and ornamental trees, not shearing, to maintain plant form, density and size. Annual pruning is recommended as part of a standard maintenance and estate care plan.
