How to Plant Green Mountain Boxwood

Pick a location where the soil drains quickly after a rain. Green Mountain boxwoods require moist soil in a full-sun or partially shaded area, according to the Evergreen Nursery website. Also, slightly alkaline or acidic soil, ranging from a 6.5 to 7 pH, with sand or clay supports the boxwood's growth.

Dig a hole for the Green Mountain boxwood using a shovel. Measure a diameter that is twice the width of the root ball. For example, if the root base of the boxwood measures 6 inches, make the hole 12 inches in diameter. Also, make the hole as deep as the boxwood's original container.

Place the boxwood in the hole and backfill it with the dirt. Water the Green Mountain boxwood immediately after planting it. Saturate the ground around the base. After the initial watering, water the boxwood only after an extended drought.

Add 2 to 3 inches of mulch around the base of the boxwood. Extend the mulch 12 inches past the boxwood's canopy as directed by the North Carolina Cooperative Extension Service. This helps keep moisture in the ground and prevent weeds.

Fertilize the boxwood in early spring with a 10-10-10 fertilizer. Follow the manufacturer's instructions when mixing the fertilizer. Cover the ground 6 inches out from the base, since the Green Mountain boxwood has shallow roots. Avoid fertilizing the boxwood right after planting.
