The cold hardy, drought-tolerant American Boxwood grows to a mature height of 10 to 12 feet, though it's often kept much shorter with pruning. These dark green are both pest and disease resistant, and can withstand excessive snow and ice without breaking.
Also known as the Common Boxwood, the American is used for dense privacy screening, edging, accents in plant beds and beyond.
When it comes to planting, you'll want to ensure your American Boxwood Shrubs are spaced 3 to 5 feet apart and planted in full sun to partial shade (anywhere from 4 to 8 hours of direct sunlight daily).
For the most part, American Boxwoods simply prefer well-drained soil, though their optimal soil pH is 6.5 to 7.0. They have a moderate tolerance to salt as well!
To plant your hardy American Boxwood, remove all grass and rocks from the planting area, and break-up any existing clumps of dirt. Dig a hole slightly shallower than the height of the root ball, and place the boxwood into the hole, leaving just the tip (the root flare) of the root ball above the ground. Slowly return half the soil back into the hole, pack it firmly, and water well. Then, finish filling the hole with the remaining soil, and water slowly at the base.
Fertilizing your Boxwoods can promote root growth and provide the best results, especially when you fertilize in late fall. A 10-6-4 granular product is best, and it should be applied around the base of the plant, just beyond the drip line, where the most active roots are located.
