More About American Pillar Arborvitae
The American Pillar can reach from 20 to 50 feet high, depending on the environment. Still, you can find some dwarf conifer varieties growing in container sizes.
Yet, the hedge American Pillar Arborvitae is exceptionally growing on a border. With its versatility, it grows as an ornamental plant in a small garden. You can grow some cultivars that only reach a height and width of 20 inches.
In the Thuja occidentalis genus, you find over 300 species with large shapes that grow conical or with a narrow pyramid shape to round. The trees grow a single trunk with a diameter of 3 feet wide.
The tree’s bark is reddish-brown with furrowed trenches and turns gray as it matures. At the same time, the foliage color is green or golden. The bark also shreds off in strips, growing in swamps to wet forests.
The problem is that the trees are not deer resistant, and it is best to keep them in mind when planted in the yard.
When to Plant Thuja Occidentalis American Pillar
The best time to plant your Arborvitae trees is in the fall. You find the trees becoming dormant at the end of autumn. Alternatively, you can plant it in early spring before new growth starts.

The American Pillar Arborvitae is also referred to as the Full Speed-A-Hedge. It has a dense growth habit that works well in most properties. But before we care for the plant Arborvitae, we have an exciting story to share.
One day John House was walking through his nursery and found an unusual branch mutation. This 85-year-old postponed retirement to patent the tree as he knew how valuable the American Pillar Arborvitae could be for all in the landscape.
The truth is that John was right, as it is a beautiful lush tree with dark green foliage year-round. You need not concern yourself with pine cone littering as it does not produce any.
The Best Soil Types For The Arborvitae
To plant American Pillar as a native tree, we recommend not placing them too close to power lines because of the height.
The Speed-A-Hedge American Pillar Arborvitae has a rapid growth rate. Therefore, you can plant young trees in well-draining soil but not in too-wet sites, as they can tolerate some dryness when established.
So, grab a spade to dig a hole twice as wide and deep as the root ball. You need not amend the soil but water well after placing it in the planting hole. If you want to add some nutrients, it helps to work in some compost and peat moss to make it drain well.
Still, they do prefer neutral to alkaline soil types.

Watering Your Hedge American Pillar Arborvitae
The Full Speed-A-Hedge Arborvitae trees need more water when young. Mature container plants can gather moisture from the environment if you do not live in a dry area.
While they are heat tolerant, you need to water deeply in warmer climates when the shrub stands in full sun. So, water your young trees daily for ten minutes in the first growing season.
The frequency will decrease as your trees reach their mature height. But the rule remains to keep checking the soil if it is moist.
Another helpful thing is to add some organic mulch around the tree base to retain moisture.
Temperature and Humidity

Also, do not feed your trees if they are sick, as it can stress out your plants more. The best time to fertilize your Full Speed-A-Hedge is early spring before new growth starts. It is also the only time you will feed your trees.
We recommend a slow-release fertilizer with 50% Nitrogen, like 10-8-6 or 12-6-4. Choose a granular one to prevent root burn and water deeply.
Pruning and Maintaining
When it comes to pruning your Full Speed-A-Hedge, it is best done in spring to keep the foliage neat and thick. Trim off the leafy parts on the branches, and be careful not to cut back into the bare wood.

Stick the cut end into some rooting hormone and the pot.
Water well and cover with a clear plastic bag to create a dome.
