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.

So far so good.
Big Green Fence (I hope)
Trees were delivered quickly and planted the next day, gave them a good long drink and luckily it is rainy season here. They get a daily watering, they seem to be growing already.
Very good so far. They’re just babies but they are thriving and starting to grow. My hope is that they grow fast and provide beauty and privacy.
Thuja Green Giants order;
Very happy with the trees & the service I received. I was shorted 1 tree on my order & when I contacted the company they promptly sent me an additional tree. The trees arrived in very good shape & my only concern is that they were planted during this heat wave that has spread over the country. I have been very diligent in making sure they have been watered sufficiently & so far so good. Thank you for the excellent service.
Finding and ordering, was vary smooth. Shipping was more like 2 or 3 days, but I blame that on the vast amount of stuff that is being shipped these days. Plants arrived looking alive and ready to rock. All in all, it was most excellent.
