Planting a Wintergreen Boxwood Hedge: Korean Cultivar for Cold Climates

Overview

Wintergreen boxwood (Buxus microphylla ‘Wintergreen’) is a Korean native forming a rounded 2–4 ft hedge with delicate foliage. Excellent cold tolerance; ideal backdrop for flower beds.

Step 1: Site Selection

Well‑drained sandy loam, full sun to part shade.

Step 2: Soil pH

Target 6.5–7.0. Test and amend with lime (raise) or sulfur (lower).

Step 3: Planting Hole & Spacing

Hole 2× root ball width, same depth. Set at container level. Space 3–4 ft apart for hedge density.

Step 4: Watering

Water deeply at planting. Weekly through first summer. Yellow leaves = underwatered.

Step 5: Mulch

2–3 in. mulch, 12 in. radius from stem. Conserves moisture, suppresses weeds.

Step 6: Fertilize

Early spring, balanced 10‑10‑10, 6 in. from stems. Before new growth emerges.

Long‑Term

Shear lightly after spring flush. Thin annually for airflow. Protect from winter wind.
