Product Description

*If you would like to be added to the Thuja Green Giant wait list please send us a message via our chat or email*

The Thuja Green Giant tree will add a lush, green privacy screen to your yard in no time! One of our most favorite and fastest growing trees.

The National Arboretum presents the ‘Green Giant’ which is a vigorously growing, pyramidal shaped evergreen with a dark green color that remains outstanding throughout hardiness range. Green Thuja is perfect for privacy tree needs as it is a hybrid of the thuja plicata tree that graces the northwest. 

The Thuja tree is ornamentally appealing as a single plant, specimen tree, a dense screen, or as a living frame for your landscape or garden. Plant your tree at your property line for ultimate privacy function. Don’t worry about the deer! It is deer resistant.

Thuja Green Giant arborvitae is a large, evergreen sentinel in any landscape. Living up to its name, this “giant” tolerates a wide range of soil and growing zones and has very few pest or disease problems on its rich green foliage. Check out our Pests and Diseases blog for more information on Thuja Green Giant tree problems.

Thuja Green Giant Care

The thujas hardiness zones are best in the department of agriculture plant hardiness zones 5-9 across the United States. This landscape tree performs best in moist, fertile, well-drained soil conditions in full sun to partial shade. Ideal conditions for the giant Thuja tree are at least 4-6 hours of sun per day. This large tree cannot handle wet sites or poorly drained soil types like heavy clay because of the possibility of root rot.

The Thuja Green Giant Arborvitae growth rate is extremely fast! It can grow up to 3-5 feet per year once established; and it can quickly reach a height up to 40 feet tall and 20 feet wide at maturity. As young plants, they grow faster during the spring and summer growing season more than any other season.

Slow release fertilizers at the base of the root ball will help give this tree the boost it needs in early spring. The emerald green needles may darken or bronze slightly in winter. If the leaves turn brown you may have a different issue such as lack of watering.

Newly planted trees need lots of water and a thick layer of mulch to help retain moisture and protect the roots. Water your trees a few times a week, especially during the summer months when temperatures are hotter. The root system will establish after 1 year if watered thoroughly. After 1 year of fast growth, it is fairly drought tolerant.

The best time to plant Thuja Green Giant shrubs is in early spring so the trees have the whole growing season to establish before the ice and snow of winter come. Dig a hole the size of the root ball and don’t plant too close! Thuja Green Giant hedges will establish quickly and provide the privacy you need.

Planting Thuja Green Giant Plants

Wondering how far apart to plant arborvitae? Thuja Green Giant spacing should be planted at least 5-15 feet apart because of their girth and length. This will leave plenty of room to grow! Some use it as a screen plant or hedging plant to line a fence in their yard in a straight row of trees. You can also do it in a double row spacing as long as you have a wide area so they can reach their mature width.

Bushier than our Leyland Cypresses, but still the same Christmas tree like form. You can prune your Thuja tree into a shorter hedge for a single row spaced and keep the height at 12 to 15 feet tall if desired. They can tolerate a heavy shearing and we encourage pruning to promote new growth.

Shipping Info

Once your Thuja Green Giant order is placed, we will ship your plant(s) within seven business days year round unless during the checkout process you request otherwise in the space provided to do so.

Perfect Plants’ shipping specialists carefully package your plants using a proven packaging method that ensures your plants arrive healthy, colorfully alive and ready to flourish. We’ve coined the term ‘upside down box test’ and we do just that; we carefully package so that regardless of the direction your box is handled, it will not harm your precious plant that’s inside.

upside down test

No shipping process is without a problem from time to time. On rare occasions some plants may experience some of the following during their transit: drooping, minor leaf-loss and/or minimal yellowing/discoloration, minor limb damage, etc. These instances are quite rare, but can happen when shipping plants in boxes.

Plants normally recover within a few weeks after planting. If a damaged box has injured your plant on the inside, please notify us within 5 days of receiving you package(s) by emailing us a photograph of the damage.

We always do our very best to ensure that your plants are packed and shipped in the safest, gentlest and most effective way possible.

Will my plants and trees look like the photographs?

Absolutely! Unlike other online nurseries, our photos are of actual plants and trees we’ve grown here, on our family operated nursery.

our story Lloyd nurseryGrowing our own plants and trees helps to ensure we ship you the best quality plants that are free of pests and diseases.

Your plants and trees may however not ship with flowers on them, like the photographs. This all depends on the time of year you buy your plant or tree. Crape Myrtle trees, for example, only bloom during the summer months, so if you purchase one during the spring or fall, they would ship without flowers. Once planted, your plants will grow and thrive giving you flowers for many years to come!

Pot Sizes

Pot sizes (commonly referred to in gallons) are shipped in the same size nursery trade pots which may vary in actual volume. Some plants may have been at the approximate pot size listed, but require excess dirt to be removed so that you will not be paying any additional shipping costs. This doesn’t happen very often though.

Shipping Fees

Our shipping charges are based on the value of your order.  Please use the chart below to see what your shipping charge will be.

The Thuja Green Giant prefers full sun or partial shade and fertile, moist and well-drained soil. It is reasonably tolerant of most average soil types however. The Green Giant is reasonably drought tolerant, but should be watered regularly until established. It can be planted as a standalone majestic focal point or as a hedge to form a dense visual, sound and wind barrier.

The Thuja grows very quickly once fully established, but large growth spurts may not be seen until the trees second or third year of growth. If utilizing as a hedge, space the trees’ centers 8 to 14 feet apart, depending on how tight of a barrier you hope to achieve. Tighter plantings will mean more shearing will be necessary to maintain shape and health, wider spacing will allow the tree to maintain it’s more natural pyramid shape.


Dig a hole approximately twice as wide as your new plant’s root ball and deep enough so that the top of the root ball is equal with the ground level.

Loosen the root ball using a small garden spade or by hand. Breaking smaller outer roots can encourage growth into the new soil, but take care to not damage large primary roots.

Place the plant in the hole and ensure that it is situated evenly upright. Use the excavated soil to fill in around the root ball, using your foot to pack it in firmly. Thoroughly soak with a hose as you fill in the dirt. Take great care to not leave any gaps or air spaces around the root ball as this could kill the plant.

A 2-4 inch layer of mulch is strongly recommended to help retain moisture and discourage weed growth. Apply mulch over the entire planting area but keep away from the stems or trunk by a few inches. Ensure that the plant and surrounding soil is completely soaked with water.

To ensure the proper nutrients are available for the life of your Thuja, our proprietary Perfect Plants Special Blend Soil and a once yearly application of Nutricote Total 360 Fertilizer are great considerations for your new plants!

    I ordered 8 of the Thuja Trees 5-6ft and they came in packaged perfectly. I was somewhat concerned about how the plants would look after shipping. They came in unbroken and looking great! My wife was very happy.

    The thuja’s were our idea of a ‘green fence’. After calling and speaking with Natalie on the phone, we made our purchase of the 5-6ft trees. They came in perfect packaged and healthy. This company did a great job growing such nice trees.

    My neighbor had some Thuja Green Giants installed by a landscape company and was charged a fortune. Bought online with shipping was 1/2 the price he paid and I will install them myself. New to online plant shopping but they looked good coming out of their HUGE box.

    We bought 3 of these to hide the nieghbors house from our pool. We live in Atlanta, Ga and its a very common tree around our neighborhood so we thought we would try our luck with 3. Trees arrived 5ft+ tall and large. My husband was less than thrilled with his honey-do list this weekend but he got the job done. Trees look great!

    Ordered 12 3′-4′ Thuja Green Giants. First, 8 were delivered: 4 were 4 1/2′ and 4 were 2 1/2′. Not good for planting along a fence. I called and asked that they replace the 4 short ones that were not even the minimum of 3′ (per my order) and make sure those and the last 4 were on the “taller side” to match the ones I got (thinking closer to 4′ than 3′). Long story short, after days of back and forth, I ended up with 16 trees ranging from 2 1/2′ to 4 1/2′, and the “replacements” and last 4 of my order barely made it to 3′. I had to order another 4 in the 4′-5′ range, just to get some more to match the first ones they sent, so I ended up with 20 trees instead of 12. It wouldn’t have been so bad if they hadn’t “exceeded” my expectations with the first at 4 1/2′. Trees come healthy and beautiful, but their “fulfillment” leaves a bit to be desired. They did give me a discount on my last 4 larger trees ordered.
