Thuja Green Giant Jumbo Gallons Description

These are  extra large 3-4'tall Thuja Green Giants in 1 Gallon Containers!

 No other plant can beat Thuja Green Giant for creating a colorful, evergreen privacy fence in your garden.

This rapidly growing evergreen Hedge Plant can grow over 3' per year if given copious amounts of water and fertilizer throughout the growing season.

Thuja Green Giant is also extremely adaptable to a wide range of growing conditions and will thrive in both sandy and heavy clay garden soils!

Green Giant also has intensely fragrant  foliage that makes wonderful cut branches for Holiday arrangements!

Fertilizing: We use Osmocote Slow-Release Fertilizer, available at any good garden center. Place 2 tablespoons in bottom of each hole prior to planting. This feeds your Thuja all year long & is only done once per year.

Long-blooming Knock Out Roses, drought-proof Sedums, & easy Ornamental Grasses make perfect companion plants to Thuja Green Giant.

Thuja Green Giant thrives in full sun to part shade. Foliage grows right down to the ground and can be sheared to desired shape. A simple shearing once a year is all it takes to keep this colorful, adaptable, and fragrant evergreen shrub in bounds!

Green Giant Thuja even thrives in the intense heat and humidity of Atlanta, Georgia and can tolerate prolonged periods of drought after it becomes established!

Arborvitaes such as Thujas are more drought tolerant than Leyland Cypress with denser, more attractive foliage. Superb alternative to Hemlock in the north.

Special Features: Cold Hardy, Cut Foliage, Disease Resistant, Drought Tolerant, Easy Care, Evergreen, Fast Growing, Fall Color, Fragrance, Heat Tolerant, Rabbit Resistant, Winter Interest

Ideas and How-to's



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 overwater. 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.

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. Also, all the assistance I received from the lady I dealt with on the phone during my ordering, rescheduling, increasing the quantity of the order, to actual delivery...she was so very helpful, gracious and patient.

"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."

Great Plants!!
