Thuja Green Giant- Jumbo Arborvitae Gallons Description

Green Giant Arborvitae

‘Green Giant’ arborvitae (Thuja plicata x standishii) is a fast-growing evergreen, with dense foliage and the ideal size for creating privacy or hiding unsightly views. Growing up to three feet a year, ‘Green Giant’ can create a lush green wall that provides four seasons of privacy in just a few years.

No other evergreen can beat ‘Green Giant’ arborvitae for creating a colorful, fast-growing, privacy fence in your landscape. This award-winning introduction from the U.S. National Arboretum is regarded as the most distinguished landscaping tree in America, and it's our #1 best-selling privacy tree; count on it to provide years of ever-increasing beauty!

When you order trees from, you'll receive 3 feet tall, floor to tip, ‘Green Giant’ arborvitae plants in 1-gallon containers! These plants have been grown for over 2 years, and carefully hand-selected for the highest quality before shipping. Compare and you’ll see, the size and quality we offer cannot be beaten at this price.

Fast Facts:

Growth rate:

‘Green Giant’ Thuja can grow more than 3 feet a year under ideal conditions, described below. Left to grow for several years, your trees can eventually reach heights of up to 50ft, with a width of more than 10ft, both of which make it the ideal plant for a privacy hedge.


A single row of ‘Green Giant’ planted 5ft apart will maximize coverage while keeping the cost low. If space and budget allow, two staggered rows – with two rows of trees each spaced 10ft apart - is useful for a little added privacy, as well as noise reduction.


While our ‘Green Giant’ plants start at around 3ft, they grow quickly, eventually reaching a height of 50ft, growing over 3ft every year in ideal conditions. If you desire slightly smaller arborvitae, consider Full-Speed-a-Hedge® ‘American Pillar’ or North Pole®.


‘Green Giant’ have a lifespan of at least 40 years when properly cared for, although many species of arborvitae live much longer, with lifespans stretching beyond 200 years. Since Green Giant is a relatively new cultivar, it hasn’t existed long enough to truly test its lifespan.


Thuja can grow in a variety of conditions, but for optimal growth, avoid soggy or waterlogged soil. ‘Green Giant’ does best with moist, but never wet, soil. A 2-3” layer of mulch is recommended to help the soil retain moisture and protect the roots from both heat and cold.


Adaptable to a variety of soil conditions, Thuja can handle both sandy and heavy clay garden soils. They thrive in both acidic or alkaline soils. They can be sensitive to salt, so they are not recommended for planting near busy roads.

When to Plant:

Plant ‘Green Giant’ in either spring and fall, and even into the early summer in some climates. The goal is to plant your ‘Green Giant’ when the weather is cool, but not cold – after the last frost in the spring, and a 6-8 weeks before the first frost in the fall. This gives the plant plenty of time to grow roots before conditions become stressful.


To achieve the fastest growth rate, fertilization is important. We recommend applying a granular rose, garden, or tree and shrub fertilizer in early spring, just as the ground begins to thaw. You can make additional applications in late spring and early summer if you wish.

How to Plant:

  1. Identify your planting locations
  2. Dig a hole twice as large and as deep as your root ball
  3. Remove the ‘Green Giant’ arborvitae from the container
  4. Tease apart the root ball and place the plant upright in the hole
  5. Backfill the hole with soil
  6. Water the area with about an inch of water
  7. Apply 2-3 inches of mulch to the planting site
  8. Continue to water weekly. The soil should never be soggy, nor should it be allowed to dry out completely, especially during its first few years.


Thuja Alternatives:

If ‘Green Giant’ is a little too tall for your taste, there are several other arborvitaes that can fulfill a similar purpose while maintaining a smaller size. Full-Speed-a-Hedge® ‘American Pillar’ and Emerald Green arborvitae both grow tall enough to create a full-size privacy hedge, but take up a bit less space.


Fun Facts

  • Likely the first North American tree brought to Europe, having been grown in Paris since about 1536 after being discovered by French Explorers.
  • The foliage and bark are high in vitamin C, which helped French Explorers Combat Scurvy.
  • As such, the tree was given the name arborvitae, Latin for tree-of-life in 1558.
  • The wood was also used for canoe frames by Native Americans due to its light weight.
  • In the modern-day, the wood can be used for poles, posts, and lumber.
  • Arborvitae has also been known to attract birds, providing a source of food & cover.
  • Arborvitae grows natively in much of the Northern US and Canada.
  • This specific cultivar was bred in Denmark and brought to the U.S. National Arboretum in 1967 by D.T. Poulsen.
  • Perhaps one of the most famous Thuja trees is the “Witch Tree” in northern Minnesota
    • While cultivars like green giant will have their foliage spread to the ground, many Thuja only has foliage near the top, for maximum sun exposure.
  • While the Eastern US is home to Thuja occidentalis, which reaches a maximum height of around 80ft, the Western US is home to Thuja plicata, which can grow up to 230ft.
    • As a result, the largest living Thuja plicata is the Cheewhat Giant – boasting a volume of 15,780ft3

Common Names

  • To the general public, Thuja goes by many more common names, including:
    • northern white-cedar or whitecedar
    • eastern white-cedar or whitecedar
    • arborvitae
    • American arborvitae

Soil: Best grown in moist, fertile, well-drained soils. Tolerates somewhat wide range of soils and some dry conditions. Poorly drained and wet sites should be avoided, and it is very salt-sensitive.
Light: Full sun (6 hrs direct light daily), Partial sun/shade (4-6 hrs light daily)
Water: Keep moist, but do not over water. Appreciates well-drained soil.
Spacing: 3 - 5 ft
Fertilizing: Top dress in spring with a slow release, balanced fertilizer.
Winterizing: Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder zones. Tolerates wind once established, and withstands heavy ice or snow. Darkens or bronzes slightly in the winter. Note -- The oldest, interior branchlets on an arborvitae normally turn brown and fall off in autumn. This aging process is different from drought stress, which on arborvitae appears on the tree outside the interior foliage as an abnormal yellowing or browning, known as flagging. This discoloration may not appear until a season or two after the drought stress was most severe.
Maintenance & pruning: Requires little or no pruning but can be sheared easily if necessary. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any die back.

I ordered 12 of these and was very impressed right away. They arrived in excellent condition and about 3' tall. Planted them all the next day and so far they look great and I'm hoping they come along great with hot days coming. Great experience with this company and will definitely order from you guys again and reccomend you to my neighbors too.

These are not one gallon pots! If you are expecting to be sent what is described then you will be very disappointed. We received 2.75 quart pots=.0.6875 gallon. With such tiny pots and tiny stems, we will be lucky 10 of the 36 we bought will make it.
Owner Response: Our trees are grown in a Landscaping Gallon pot. I see that Amy is working with you to resolve any issues you might have on the trees. --- Management

I have ordered 24 of these trees. They arrived nice and green. One was snapped at the top and damaged, I am waiting to see if the company will replace it. They are very floppy. I am not sure if I am supposed to stake them. A couple that have been in the ground for a bit are turning brown (despite watering). So we will see what happens. They are nice and bushy for the price. I hope they live!
Owner Response: Your replacement was delivered 6/10/20. Please keep us informed as to how the others are doing. Staking the trees is a good idea while they establish their root system. We recommend one inch of water per week, and good drainage. Please send us any pictures of ones that concern you.

We're really happy with these plants - ordered an additional 12 trees after my initial 16 tree order. All look great, are the size expected or larger & received in great condition. They are bent over at the top due to size so we staked them & expect the soft new top growth will straighten up eventually. Packaging was protective & practical when ordering so many trees at once. 2 trees boxed end to end with plastic around each pot to keep the soil intact & shipped in another larger box, 8 per box. Took a while to get them unpacked & I have a never ending pile of cardboard to recycle. Great price & glad I could have these shipped.

So far so good...

Received and planted 24 Green Giants yesterday delivered by fedex. Guy tossed first box out of truck then saw me and was much better with next two. Trees arrived in good shape, minus one with trunk branch snapped about 7 inches down, probably fedex guy tossing box. All others look great, full, fresh and 34 inches in average height. I hope the broken one recovers. Can't wait to see them grow and will update review come winter. Easy ordering good customer support.

Received and planted 24 Green Giants yesterday along road to make shrub to block out view and noise. Trees arrived via fedex in really good shape and only one had damage with top of tree broken about 7 inches down. Probably from fedex tossing boxes. Good full growth in stress with average height around 34 inches so happy there. Planted 5 ft apart and will keep you posted on growth. Very happy with the order but concerned on one damaged tree, fingers crossed.

Plants arrived lively and green, but two of the four were pretty bent up in the packaging. Also, even when straightening them out... they fell short of the 34" average. Closer to 26". Hope they make it...

I ordered these in 2010 (1 dozen) and then again in 2016 (1 dozen). Was very pleased at the time. Prices have gone up but descriptions haven't changed, and this year's order is noticeably smaller, even the planting container. They are packaged differently now, too...much tighter and less individual care for the plant. They used to come in more boxes and tied to a bamboo stick. Called and spoke with someone and was informed it's size variation, but that doesn't explain the smaller container or packaging. If the product changes, then the description should change (particularly if increasing prices). On top of this, less than 50% of my order even arrived --- I ordered two other types of plants, and I was told "Well, I have over 1000 order to get through so I'm sure yours is in here somewhere." Customer Service tip: that's not what customers want to here. So, in 2010 and 2016, I say the product and service was 5 star. Now, I would definitely recommend going local if not for the global pandemic.
Owner Response: Hello - I apologize for any inconvenience this has caused you. I will speak to customer service about response. We have changed packaging since 2016, and I will let our shipping department know your concerns. The trees are grown in the same size container as they always have been. I will extend your warranty to make sure your plants get a good start. I have noted all of your concerns in your order and extended to 6/20/2020. Please let us know before that date if you have any more issues. - Management

I ordered 36 of the green giants. The majority of them were undersized. One has died since May. I contacted customer service and sent pictures and never heard anything back. Their customer service is a joke. Look elsewhere.
Owner Response: I apologize for the inconvenience to you. I see from the notes in your order that we spoke to you in May and then again in August several times about this issue. I have issued you another 20% discount for all your troubles. Your original order had 20% off the entire order so with this discount you are getting 40% off your entire order. Please allow 7-10 business days for our accounting department to issue you a check. -- Pam -- Office Manager

I bought 24 fast growing arbs. They came in narrow boxes with no damage. 90% of them would meet the 2.5 to 3 foot size. I did have a couple that were smaller. I planted as they told us. Now its end of July and HOT!! All trees alive and well. When researching these trees, I found that first year growth is very slow. They are rooting first year and searching good soil. The next year a little growth will occur. The third year is when the crap hits the fan and they start growing 3-4 feet per year. My trees after a couple months are green and look the same size. No dead branches to see. I got lucky on the rain in May and June. Didn't need to water at all. I did keep the grass down around these trees for max growth. I will fertilize in the fall. So far looking good. fast shipping and no damage. Planted these in central PA.

I purchased 12 Thuja Green Giant trees at the end of 2017 for spring delivery in 2018, so they all arrived about the end of April 2018. We planted them shortly after they arrived and they seemed to take off in growing and grew about a foot that summer. The winter of 2019 was a bit rough and in early spring many of them had sustained browning. In doing my research on the possible causes of the browning of my trees, I found that probably what happened was not enough water prior to winter. Fortunately, we had a wet spring and they seemed to have bounced back from the rough winter. They appear to have bounced back from the winter and are now growing-looking forward to measuring to see how much they will grow this season. I am planning on purchasing more as we are not finished with our hedge, but wanted to see how well our first 12 did and they are thriving.

Bad experience do not recommend

I made a big purchase of 16 of these trees. They were all packed in such a way that arrived bended and looking terribly distressed. All of them. I contacted the seller immediately and they assured the plants would "eventually" recover. They even suggested I should stack them all to help them. Well I did it all, they never improved. Finally after several emails I got 3 replacements (out of 16). They arrived in similar conditions. It has been well over a month and they are looking so bad, a few are looking nearly death, that I'm constantly been asked by neighbors what's wrong with these plants and where did I get them from. This review is for the online shoppers: don't purchase trees here, go to your local nursery and you'll get healthier better plants. I lost over $300 and a lot of time and effort buying here. Hope my experience helps...
Owner Response: Laura - So sorry to hear you are still having issues with the trees. Please give us a call at your earliest convenience so we can resolve this issue. Our office hours are 9 - 2 EASTERN Monday - Friday. Pam - Office Manager

I spent a lot of money on these buying 10 of them. First winter they didn't hold up well. All 10 of them are 80-95% brown with very little green as of today (mid June). They're still green if you check under the surface of the trunk, but they haven't grown an inch and are very sickly looking and not at all thick or filled out.
Owner Response: I am sorry to hear about this, according to our records you are in a zone 4, and the Green Giants are only hardy to zone 5. As winters get harsher in the United States it will get harder on certain plants too.

Great plants for a very competitive price.

Duncan Smith  |  Sep 24, 2018
We ordered these trees and when we did the site claimed 4+ feet per tree. First they don't tell you that they are from the bottom of the pot to the very top of the longest stretched single strand. The trees arrived and they were skinny, not in great shape, yellowing, and some weren't even 3 feet tall including the pot. Upon contacting the company they first did offer a 25% discount, which would have been moot because we didn't pay for those sad, small trees. They could not send us any larger trees and the story changed from "yes the site did say they were larger when your ordered them" to "they have never been more than 3+ feet tall". I went to Home Depot to find $20 trees of this type which were in 3 gallon pots, much fuller, and in way better looking shape. More over I wouldn't have had to wait almost a month for them. I also understand that by writing this review the company may retract the refund, but what happened to us must be told to others. If you want to save money and time, just steer away from this company. The trees on the site in the pots are NOT what you get when you order. Their site doesn't have the option to upload a photo, or I would show their sad specimens vs what a Big Box store can provide for a comparable price.
Owner Response: Hello Mr Smith - We try to keep the website updated with sizes of plants that are shipping. After reviewing your order, I do see that we have refunded you 25% of your order. I am glad that we were able to come to a mutual solution for your issues. Mary

Was amazed at how the dozen I ordered looked when I unboxed them. Way better condition than many trees I've paid more for a the big box stores. Granted, they were only in transit for 3 days which may be a factor healthwise, but it looked like the FedEx folks played contact football with the boxes, yet all 12 were unscathed! Talk about a hearty tree!! 4 months later, after planting in our northern Kentucky yard that's 95% clay you could sell to a pottery shop, they're kickin so much a**!! Already seeing plenty of new growth and just finally got around to fertilizing. Transaction couldn't have gone smoother. I'd recommend this company to ANYBODY who'd listen.

This email is long overdue...I made a purchase of your Thuja Green Giants in 2013. I had to reschedule my order delivery twice. Then I increased the order to a total of 20 of these trees. The trees were in absolute perfect condition, as well as perfectly packed for shipping. I haven't lost one! They are everything you advertise! I have wanted to send this THANK YOU for some time.

"Just to follow up- ALL my Thujas have grown and done well. I ordered 1 gallon Thujas from another company- and while they were in great shape and much cheaper- they were significantly smaller than the ones that you get at Great Garden Plants. If you're looking for true jumbo 1 gallon Thujas, I would say Great Garden Plants are a good choice for a larger start."
