Compact Boxwood
Buxus sempervirens 'Suffruticosa'
shrubCompact boxwood is a slow-growing, evergreen shrub prized for its dense, fine-textured foliage and ability to be shaped through pruning. It is one of the smallest cultivars of common boxwood, reaching only 3-4 feet tall at maturity, and has been used for centuries in formal gardens, hedging, and topiary work. Its tolerance of shade and low maintenance make it an excellent choice for borders, edging, and ornamental designs.

Light pruning to encourage branching. Maintain consistent moisture. Light fertilization in spring with balanced fertilizer.
Shaping & Pruning
Year 3 onwardsMature foliage with dense branch structure; responds well to formal pruning and topiary work
Prune in late spring (May-June) after new growth hardens off. Avoid heavy pruning in fall. Shape hedges and borders with hedge shears.

Common Pests
-
Monitor in late spring for leaf blistering. Prune and remove affected leaves. Apply insecticidal soap in May-June targeting adults before egg-laying. Use systemic insecticide in severe cases.

Increase humidity with regular misting. Spray undersides of leaves with water to dislodge mites. Apply horticultural oil or miticide in early morning or evening.
-
Minor pest causing leaf cupping. Prune out severely affected foliage. Dormant oil spray in early spring before bud break.
