When To Plant Thuja Green Giant Trees

Like most trees, Thuja green giant trees can be planted in just about any month of the year. However, the best time is in the spring, allowing them a full growing season to establish its roots before its first winter.

How Fast Do Thuja Green Giants Grow?

The Thuja Green Giant Arborvitae growth rate is extremely fast! It can grow 3 to 5 feet per year once established, and it can quickly reach a height up to 40 feet tall and 20 feet wide at maturity. As young plants, they grow even faster during the spring and summer growing seasons.

Do Deer Eat Thuja Green Giant?

Thuja green giant trees are deer resistant. They’re a great tree to plant around your perimeter to deter deer from some of your other plants that may be more susceptible to being eaten.

Are Thuja Green Giant Roots Invasive?

Thuja green giant trees are not invasive in the traditional sense. However, since the tree can grow to be over 40 feet high, the roots will spread wide and deep to support the tree’s size and weight. Make sure your Thuja green giants have ample space to grow.

THUJA GREEN GIANT CARE

The thujas hardiness zones are best in the Department of Agriculture plant hardiness zones 5-9 across the United States. This landscaping tree performs best in moist, fertile, well-drained soil conditions in full sun to partial shade. Ideal conditions for the giant Thuja tree are at least 4-6 hours of sun per day. This large tree cannot handle wet sites or poorly drained soil types like heavy clay because of the possibility of root rot.

Slow-release fertilizers at the base of the root ball will help give this tree the boost it needs in early spring. The emerald green needles may darken or bronze slightly in winter. If the leaves turn brown you may have a different issue such as lack of watering.

Newly planted trees need lots of water and a thick layer of mulch to help retain moisture and protect the roots. Water your trees a few times a week, especially during the summer months when temperatures are hotter. The root system will establish after 1 year if watered thoroughly. After 1 year of fast growth, it is fairly drought-tolerant.

The best time to plant Thuja Green Giant shrubs is in early spring so the trees have the whole growing season to establish before the ice and snow of winter come. Dig a hole the size of the root ball and don’t plant too close! Thuja Green Giant hedges will establish quickly and provide the privacy you need.

Planting Thuja Green Giant Trees

Wondering how far apart to plant arborvitae? Thuja Green Giant spacing should be planted at least 5 to 15 feet apart because of their girth and length. This will leave plenty of room to grow! Some use it as a screen plant or hedging plant to line a fence in their yard in a straight row of trees. You can also do it in a double-row spacing as long as you have a wide area so they can reach their mature width. 

Bushier than our Leyland Cypresses, but still the same Christmas tree like form. You can prune your Thuja tree into a shorter hedge for a single row spaced and keep the height at 12 to 15 feet tall if desired. They can tolerate heavy shearing and we encourage pruning to promote new growth.
