NORTH STAR® Boxwood

Zone: 5, 6, 7, 8, 9 Exposure: Full Sun, Part Sun, Shade Height: 2-2.5' Width/Spread: 2-2.5'

North Star® boxwood is one of the most reliable plants you could ask for. It stays small without much, if any, intervention. It retains a healthy green color year round, but especially in winter when it matters the most. It has a dense habit, perfect for creating a uniform visual barrier as edging or a low hedge. When it comes to the ever-feared boxwood blight, it’s even shown rather good resistance. If no nonsense elegance is your aim, put North Star boxwood in the game.

Light: Boxwood is one of the only shrubs that reliably thrives in full sun to full shade.

Soil: Any well-drained soil will do; though it is a broadleaf evergreen, acidic soils are not preferred – very slightly acidic to slightly alkaline soils are best.

Water: Average water needs. Though boxwood can show some drought tolerance, excessive dryness causes stress that can lead to pest and disease issues.

Fertilizing: Little needed; one early spring application of a granular fertilizer formulated for woody plants is sufficient, unless plant experienced severe winter stress.

Pruning: Sprinter boxwood naturally grows into an appealing globe shape. It may be trimmed if desired – do so after the new growth has emerged but before it hardens off, usually late spring. Remove any winter damaged portions in early spring.

Other: Because it is an evergreen, boxwood can be susceptible to winter damage, with leaves turning bronze, brown, or tan. Minimize any winter damage by keeping the plants covered with a good 2-3?/5-7cm layer of shredded bark mulch. If autumn weather has been dry, water plants by hand up until the ground freezes: winter drought stress is the biggest cause of winter damage on boxwoods.
