The Fastest Growing Quality Evergreen
Why Thuja Green Giants?
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.
Planting in Rows
There are two popular ways to plant your Thuja Green Giants:

How to Get the Height You Want
Follow this spacing chart when planting in a straight row:
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.
Why Fast-Growing-Trees.com is Better
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.
Our Thuja Green Giants are hybrids grown from branch cuttings - not from seed. They need to grow below the ground before they can grow above the ground. Some nurseries sell freshly rooted cuttings, which can take up to a year to reach the size and root mass of our trees.
But you can be assured that when you order from Fast Growing Trees, you are getting well-rooted Thuja Green Giants, ready for explosive growth. And for quickest privacy, we now have a limited supply of large trees available. These larger trees offer more developed branching for ready-made privacy in your landscape.

Planting & Care
1. 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.
2. 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.
3. Fertilizing: For optimal growth feed your Thuja ‘Green Giant’ with a balanced evergreen tree and shrub fertilizer starting in the spring.
4. 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.
FGT 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.

United StatesGreat trees
Bought 12 of the 1-2 ft trees about 4 years ago from here. Not much happened the first year, the second year they grew a foot or two, but the last two years they shot up like crazy. They are at least 10ft now and super healthy. Picking up a few more to finish the side yard.
United StatesNo growth
We purchased 20 trees in total. They looked good upon arrival, they still look good except the ey are only 2-1/2. - 3 foot tall. T he ey have only doubled in size since we purchased. Way short of the 3-4 feet per year. I’m sure they will be mature height in about 40 years.
United StatesGreen Giant
I have had these before and was amazed at how fast they grow and love the look. Recently bought 5 and planted them at our new house. When Spring returns, I will be adding more to my landscape for a beautiful privacy look.
United StatesHealthy and Hardy
You all have the best quality trees.
United StatesToo early to tell
Trees arrived healthy and I’m assuming teary are resilient as four of them had zero planting material in the pots and all of them were extremely dry. Exited to see how they do over the next year
