How to Care for an Emerald Green Arborvitae


Emerald arborvitae (Thuja sp. Emerald) is also known as an Eastern white cedar. This is a very popular, columnar evergreen that can grow up to 40 feet. Used often in foundation plantings or as a screen, this arborvitae is fast-growing, with dense, emerald-green foliage. It prefers full sun and fertile, well-drained, moist soil. Hardy in zones 3 to 7, this tree does best in Eastern states.

Step 1

Plant container-grown trees in the spring. Spacing should be at least 3 to 5 feet apart if planting multiple trees.

Step 2

Dig a hole with your shovel that is twice the diameter but just as high as the root ball. Loosen the soil around the walls of the hole so the roots will be able to spread out.

Step 3

Place the tree in the hole and backfill with soil, adding a bit of water as you go, to remove any air pockets. Compact the soil and water thoroughly.

Step 4

Add a layer of mulch around the tree's base, a few inches away from the trunk, to keep in moisture.

Step 5

Prune the top of the tree to your desired height or, if you wish, you can leave it as is.
