Best trees available!

These trees are fantastic. We bought the 1-2 foot small ones in 2015. They are now a beautiful emerald wall in the backyard. The privacy is great. Side note-take into consideration your sprinkler system. We will have to move ours forward this year. Pic is summer of 2022.

Best Living Privacy Fence!

I ordered these trees over 15 years ago. I think the are the best feature of our entire backyard. Planted them five feet apart and they grew quickly and are over 20 feet tall now. Our yard backed up to three other neighbors yards and this created a beautiful year round privacy fence. It been a wonderful backdrop to our yard. Can't say enough good things about these trees. So hardy even in our coldest and snowy winters and drought resistant too in our hot summers. We have never had any issues with diseases or insects. Best evergreen trees I have ever purchased.

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:

In a Straight Row	In a Staggered Row

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.

What is a Jumbo Thuja Green Giant Tree?

Jumbo trees are the most mature plants offered at Trees.com. Thanks to their well-developed root systems and large container size of 10-15 gallons, they deliver superior drought resistance, enhanced mineral absorption, and fuller growth. They're the perfect choice for instant privacy and a more established look in your landscape.

Grown in limited quantities, Jumbos are a premium option for those looking to make an immediate impact in their yard.

Why 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 Trees.com, 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.

Order your own Thuja Green Giant before it's gone!

How wide does Thuja Green Giant Arborvitae get?

Thuja Green Giant Arborvitae typically reaches 12 to 15 feet wide at maturity. If you’re planting Green Giant Arborvitae trees in a row, account for their mature width so each tree has enough room to grow into a full, healthy privacy screen.

What growing zones are best for Thuja Green Giant Arborvitae?

Thuja Green Giant Arborvitae grows well outdoors in Zones 5–8. We don’t recommend growing outside that range, since extreme heat, cold, or dryness can affect long-term performance.

How tall does Thuja Green Giant Arborvitae get?

Thuja Green Giant Arborvitae can grow 30 to 50 feet tall at maturity. Its final height depends on spacing, sunlight, soil conditions, and whether you prune it to maintain a specific privacy hedge height.

How far apart should I plant Thuja Green Giant Arborvitae?

For a tighter privacy hedge, plant Thuja Green Giants about 5 feet apart. If you have more room and want each arborvitae tree to develop a fuller natural shape, space them 8 to 10 feet apart while still creating height and privacy over time.

How long does it take Thuja Green Giant Arborvitae to mature?

Thuja Green Giant Arborvitae usually takes about 3 years to establish in the yard and around 10 years to be considered mature. Once established, this fast-growing evergreen can continue adding height and fullness when planted in the right growing conditions.

How often should I water Thuja Green Giant Arborvitae?

Water your new Thuja Green Giant every other day for the first two weeks, then every three days for the next two weeks. After the first month, water twice a week during the first year unless the weather is especially hot and dry, then increase to three times a week as needed.

Do I need to prune Thuja Green Giant Arborvitae?

You do not have to prune Thuja Green Giant Arborvitae if it has enough space to keep its natural pyramidal shape. If you’re growing several close together as a hedge, shear lightly once a year after the final frost to maintain your desired height, shape, and screening effect.

Awesome trees. com

My trees arrived and they were in perfect condition, and bigger than I even thought they would be. So I planted them immediately and they are looking good. Thank you very much!

Healthy trees

I ordered 14 of these trees at the 3-4 feet size, they were all the right size and very healthy trees. I was worried about the size as most online store tells you one size and you receive a lot smaller than advertised. These trees are very nice in color and shape as they grow. I have 15 of these on my property and added 14 more. They grow fast in a just a couple of years they will be over 12 feet high.

Trees.com Plant ExpertThanks for leaving such a fantastic review, Varouj! Expanding your screen with 14 more Thuja Green Giants to make 29 total is going to create an absolute showstopper of a privacy hedge! We know ordering online can leave folks wondering about sizing, which is why we strictly guarantee that every plant falls right within the height range ordered. If an order ever falls short, our team is always just a message away to make it right. We are so glad these arrived healthy, true to size, and ready to sprint toward that 12-foot mark!

Thuja Green Giant Arborvitae

Got them in and planted a couple months ago . Delivered in great shape . Everything looks good so far . Just a little browning on a few of them but look to be ok . Probably just where they’ve been recently planted . Ordered 20 of them 2-3 ft.

Trees.com Plant ExpertThank you for sharing your update! We are so glad to hear all 20 Green Giants arrived in great shape and are settling in nicely after two months. A little minor browning is a common reaction to transplanting as young evergreens focus energy on root development. Once those roots take hold underground, you can expect fast, vigorous growth to start pushing out. Our team is always here if you need any help! Happy growing!
