American Boxwoods prefer well-drained soil and can thrive in full sun or partial shade.

To plant them, dig a hole twice as wide as the root ball and as deep as the root system, ensuring the top of the root ball is level with the surrounding soil.

Place the boxwood in the hole, backfill with soil, and gently tamp it down to eliminate air pockets. Water thoroughly to help settle the roots and provide essential moisture.

If you're planting multiple boxwoods for a hedge, space them 2 to 3 feet apart to allow enough room for growth while creating a dense, attractive border.

Mulch around the base of the American Boxwoods to retain soil moisture and keep the roots cool, especially in hotter climates.

Water regularly during the first growing season to establish a healthy root system, but be cautious not to overwater, as boxwoods prefer well-drained conditions.
