The wintergreen boxwood is an evergreen shrub that is native to Korea and produces a round shape and has delicate foliage. Wintergreen boxwood is commonly grown as a hedge as it reaches a height of 2 to 4 feet and will spread to a width of 3 to 5 feet when left to grow naturally. The shrub winters well and complements flowering plants when planted in the background of flower beds.
Choose a planting location for the wintergreen boxwood that has well-draining soil and full sun to partial shade light conditions. Boxwood plants prefer a sandy loam soil.
Test the soil pH with a home test kit as the wintergreen boxwood prefers a pH of 6.5 to 7.0 on the pH scale. Add limestone to the soil to raise the pH number or ground rock sulfur to lower the pH number.
Dig a hole that is twice the width of the root ball and the same depth. Place the root ball in the hole, making sure the plant sits at the same depth as it was in the container or nursery. Gently pack soil around the root ball to set in place. Space the plants 3 to 4 feet apart to create a hedge.
Water the newly planted boxwood immediately after planting. Continue to water weekly to keep the soil moist during the warm summer months. Yellowing leaves is a sign the plant is not receiving enough water.
Apply a 2- to 3-inch deep layer of mulch around the planted hedge to assist with water retention and weed control. Mulch the plants to a minimum of 12 inches in diameter from the stem base.
Fertilize the wintergreen boxwood in the spring season with a balanced 10-10-10 fertilizer before the start of new growth. Keep the fertilizer application 6 inches from the stem of the plant to prevent damage.
