How to Plant Thuja Trees

Thuja trees, also known as arborvitae, are a popular choice for landscaping due to their attractive foliage and ease of maintenance. If you're interested in adding these trees to your property, it's important to know how to plant them properly to ensure their health and longevity. Follow these steps for successful Thuja tree planting.

Determine the Planting Location

First, determine the location in which you want to plant your Thuja trees. These trees can tolerate a variety of soil types but prefer well-drained soil that's on the acidic side. Thuja trees also thrive in areas with full or partial sun exposure. Ensure that there's enough space for your trees to grow and consider any potential size restrictions in the area.

Prepare the Planting Site

Before planting your Thuja trees, it's important to prepare the planting site properly. Clear any grass, weeds, or debris from the area and dig a hole that's roughly twice the diameter of the tree's root ball. Ensure that the hole is deep enough to accommodate the root system without crowding it. Loosen the soil around the planting hole to promote better drainage and root growth.

Plant the Trees

To plant your Thuja trees, gently remove any containers or wrappings from the root ball and place the tree in the planting hole. Ensure that the top of the root ball is level with the surrounding soil. Backfill the hole with soil, tamping it down lightly to eliminate any air pockets. Water the tree thoroughly to ensure that the soil is well-settled around the roots.

Water and Mulch the Trees

To promote healthy growth, ensure that your Thuja trees receive an adequate amount of water. Water the trees deeply once per week or more often if the soil becomes dry. Mulching around the base of the trees can help to retain moisture and prevent weed growth. Apply a layer of mulch that's two to three inches thick but keep it away from the base of the trunk to avoid rotting.

Prune and Fertilize the Trees as Needed

Thuja trees typically don't require much pruning aside from removing any dead or damaged branches. However, if you'd like to shape or control the size of the trees, prune them in early spring before new growth appears. Applying a slow-release fertilizer once per year can also help to promote healthy growth and maintain your Thuja trees.

With proper care and maintenance, Thuja trees can provide a beautiful addition to any landscape. Follow these planting and care instructions to ensure that your trees thrive for years to come.
