What is Thuja Green Giant

The Thuja Green Giant quickly gives you a lush, rich privacy screen (3-5 feet per year once established). And it’s:

– Drought tolerant
– Disease and insect resistant
– Easy-to-grow and very adaptable

You can block out neighbors while taking very little yard space. Thuja Green Giants grow in a uniform shape and height. You get that classic French Renaissance look without having to prune or shear. In fact, you don’t have to do anything to them. They’re drought tolerant and have no significant insect or disease problems.

How to Get the Height You Want
Follow this spacing chart when planting in a straight row:

Desired Height
Distance Between Trees
20-25 feet tall
5 feet apart
25-30 feet tall
8 feet apart
30-40 feet tall
10 feet apart

So, you’ll never have to worry about mixing chemicals or spraying these trees. With proper care, Thujas aren’t typically prone to deer or bagworm problems. This is a tough tree. Resists ice and snow damage. Grows in almost any soil, even sandy loam or heavy clays. Prefers direct sunlight, but also does well in partial shade.

The Thuja Green Giant is the perfect fast-growing evergreen for a privacy hedge or windscreen. Plant one every 5 to 6 feet and they quickly create a dense barrier. You can easily trim them once a year to your desired height. Left unpruned, Thuja Green Giants planted in rows can reach as high as 30 to 50 feet. Your Thuja foliage stays soft and thick all year long.

Some nurseries dig Thujas out of the ground and send them bare-rooted, or ‘ball and burlap.’ This can leave up to 90% of the roots behind. The tree can lose up to a year of growth while struggling to replace its root system. You also risk losing the tree, since it’s less able to absorb vital nutrients and water.

How to Grow and Care for Thuja Green Giant

Thuja Green Giant (Thuja plicata x standishii ‘Green Giant’) Growing Requirements

Hardiness zone 5-8 outdoors

Sun exposure

Can grow in a range from full sun to partial shade. They need at least four hours of direct, unfiltered sunlight per day.

Fertilizing

Should not need any extra fertilizer unless your entire lawn and garden have problems and needs regular fertilizing.

Planting

This is a large landscape tree and as such, requires a bit of planning before planting. First, measure the area where you would like to plant your hedge or row. You will need the length of the area of planting to estimate the number of trees you need.

When planting, dig a hole for each tree that is three times as wide as the root ball but just as deep. You don’t need to add anything to the planting hole. Place the tree, fill in around the tree with the same soil you took out when initially digging the hole. Finally, tamp down as you fill to cut back on any air pockets from forming, water the tree, then mulch to conserve moisture.

Watering

For the first two weeks, water your new tree every other day by holding a hose around it and counting to 20. If you don’t have a hose, 2 large watering cans full of water will do (smaller trees may only need a light soaking so a single can may suffice).

During the second two weeks, switch to watering every three days with the same method mentioned above. After the first month, water once a week unless it is dry and hot (no rain and temperatures above 80 degrees). If it is hot and dry, water twice a week. After the first six months, the trees will be established and won’t need any extra water. Your natural rainfall should be sufficient at this stage.

Fertilizing

For optimal growth feed your Thuja ‘Green Giant’ with a balanced evergreen tree and shrub fertilizer starting in the spring.

Pruning

You won’t have to prune this tree if you are growing it with enough space for it to maintain its naturally graceful pyramid shape. If you’re growing several close together as a hedge, you can shear the plants yearly after the final frost.

GCP Tip: Possibly the best feature of this evergreen is that deer don’t favor the taste. If you live in an area with heavy deer pressure, spray your Thuja Green Giants every 3 to 6 months with deer repellent. That’s all the protection you need.
