How to Plant Arborvitae Trees

Arborvitae trees, also known as Thuja, are popular for their tall, columnar shape and ability to withstand cold temperatures. They are commonly used as privacy screens, windbreaks, and ornamental trees in landscaping. If you want to add arborvitae trees to your yard, follow these steps to ensure successful planting and growth.

Step 1: Choose a Location

Arborvitae trees thrive in full sun to partial shade and require well-drained soil. Choose a location with enough space for the tree’s mature height and width, typically up to 30 feet tall and 10 feet wide for some varieties. Avoid planting the tree too close to buildings or other plants that will hinder its growth.

Step 2: Prepare the Soil

Before planting arborvitae trees, ensure the soil is adequately fertilized and aerated for healthy root growth. A few weeks before planting, incorporate organic matter such as compost, manure, or peat moss into the soil. Test the pH level of the soil to ensure it is neutral to slightly acidic, between 6.0 to 7.0.

Step 3: Dig the Hole

Dig a hole twice the width of the root ball and as deep as the container in which the tree was grown. Loosen the roots of the tree before placing it into the hole. Ensure the hole is deep enough to plant the tree at the same level it was grown in the container.

Step 4: Plant the Tree

Set the tree in the hole and backfill with soil, gently tapping the soil down with your foot to remove any air pockets. Water the tree slowly and deeply to allow the soil to settle around the roots. Add a layer of mulch around the tree to retain moisture and prevent weed growth.

Step 5: Care for the Tree

Water the arborvitae tree regularly during the first year, especially during hot and dry weather. Fertilize the tree in the spring and fall with a balanced fertilizer. Prune the tree in the late winter or early spring to maintain its desired shape, removing any dead or damaged branches. Check for pests and diseases regularly and treat as needed.

Step 6: Maintenance Tips

Pruning and shaping arborvitae trees is necessary to maintain their health and aesthetic appeal. Prune the tree annually to remove any dead or diseased branches, or to shape the tree to your desired form. Avoid over-pruning, as arborvitae trees do not regenerate growth on old wood. Watch for insect infestations such as spider mites or bagworms, and take immediate action to prevent further damage.

By following these steps, you can properly plant and care for arborvitae trees in your landscape. With their tall, columnar shape and hardiness, they are a great choice for those seeking both privacy and beauty in their backyard oasis.
