Whether you’re looking to grow a living privacy fence or cut down on traffic noise, you’ll want to check out these easy tips on how to grow American Pillar Arborvitae (pronounced are-burr-VEE-tie or are-burr-VY-tee) plants before you start.
The Perfect Natural Privacy Screen
With their tall, narrow shape and ability to grow 3 to 4 feet per year, these evergreen shrubs make a great natural privacy screen. Hardy in zones 3a-8b, they are also deer resistant and mostly disease and insect proof. At maturity, they can reach a staggering twenty five to thirty feet tall and spread three to four feet wide, making them one of the tallest shrubs around. Combine that with the fact that they are long-lived, have strong root systems, need minimal pruning and can stand up to wind and ice–and you have a standout shrub for almost any environment.
How to Grow American Pillar Arborvitae (for best results)
American Pillar do best in deeply worked, fertile, and well-drained soil. Making sure that your soil is the right consistency is key. It’s a bit of a job, so to save time and energy, the best way to prep your soil is to use a rototiller. Till down about 10 inches deep, then add 1 part peat moss or compost to 4 parts soil. This will increase your drainage.
Once you’ve got the soil prepped, you’ll want to dig a planting hole that’s twice as wide as the root ball. This will give the roots space to stretch out as the shrub matures and grows. The dark green branches are very dense, so if you’re planting them as a living fence, space them only 2 feet apart. This way they will spread into each other and create a tight, ‘living wall’.
When to Plant American Pillar
The best time to plant American Pillar shrubs is in the fall. They become dormant around early November. Or you can do it in the spring in late March before new growth starts. American Pillar Arborvitae shrubs can also be easily transplanted, even at a height of twelve feet.
Like most broadleaf evergreen shrubs, Arborvitae prefers a slightly acid soil, with a soil pH reading from 5.5 to 6.0. It is best to have soil tested before planting. If there is little organic matter in the soil, amend soil by adding peat moss or compost. Newly planted shrubs need a water-soluble starter fertilizer to boost root growth. American Pillar prefer full sun locations, but will also grow in part sun to some shade. To make this already low maintenance plant even easier to care for, use 2-4 inches of mulch around the base to hold moisture in soil.
