Planting the hearty evergreen tree known as pyramidal arborvitae is a low maintenance project for homeowners who wish to create a natural privacy screen, property border or wind block. Pyramidal arborvitae aren't overly fussy about the soil they're growing in, doing equally well in both alkaline and acidic soils, as long as the soil is moist. They do best in growing zones three through eight and favor direct sunlight, though they can still grow quite tall and strong in partial shade.
The first step in planting pyramidal arborvitae is to determine where on your property you'll be placing them. Bear in mind when making this decision that full grown pyramidal arborvitae is anywhere from fifteen to thirty feet tall, and can grow up to five feet wide. If you're planning on planting this tree to mark the borders of your property, make sure to plant far enough behind your property line to allow for outward growth so as to prevent infringing on neighboring property. Dig a hole just wide enough to accommodate the root system of your young pyramidal arborvitae trees, and just deep enough that the root system will only be covered by a few inches of soil. Make sure that the holes you've dug will position your young pyramidal arborvitae trees in such a way that they'll receive at least four to six hours of sunlight, preferably more. Cover the newly planted tree with soil and give the base of the tree a light watering to get it started. In regards to future watering, freshly planted pyramidal arborvitae shouldn't be watered on a regular basis, but rather on an as-needed basis. You can determine whether the soil around your trees needs water by simply pushing your fingers a couple of inches into the soil to see how dry it is.
When digging holes for multiple pyramidal arborvitae trees, make sure to space the holes apart from each other properly. Pyramidal arborvitae planted in a single row should be spaced at least five feet apart from each other. Double rows of trees should not only have the individual trees spaced five feet from each other, but should also have at least ten feet of space between the two rows. More than two rows of pyramidal arborvitae planted parallel to each other should increase the spacing to six feet between individual trees in the row, and twelve feet between the rows themselves.
One last aspect to consider when planting pyramidal arborvitae is the degree to which it can resist wind and survive. While they are frequently planted as a windbreak, and are effective in this capacity, they are not necessarily successful at weathering cold, forceful wind gusts if they've been planted as a single solitary row on a flat and open piece of property. They are most effective as a wind blockade when planted near other types of trees which can filter and lessen some of the force of frequent winter wind gusts.
