This Gentle Giant Will Not Disappoint!

Thuja Green Giant is becoming more and more popular among landscapers, growers, and homeowners a like.This hardy, fast growing evergreen tree makes the perfect privacy screen!

It's is a very easy plant to grow, tolerating almost any soil type and resistant to damage from ice and snow, as well as deer and most other pests.


When you are considering how to grow a Green Giant, remember that these are easy-care plants. You can shear them if you like, but pruning is not necessary. Irrigate them during dry weather even after establishment to ensure that your plants stay healthy.


Green Giant Arborvitae will grow to be 25 to 35 feet tall at maturity, with a spread of 6 to 8 feet. It has a low canopy, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 60 years or more.

This tree does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution, and will benefit from being planted in a relatively sheltered location.


Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This particular variety is an interspecific hybrid.

Plant 5 to 6 Ft. apart. Stay back 4 Ft. off property lines.​Thuja Green Giant will grow 6 to 8 Ft. wide x 25 to 30 Ft. tall. Do Not plant your Thujas closer than 5 Ft. apart thinking of quicker coverage ! If you plant to close together it will cause die-back as trees grow larger, not enough air circulation.

Thuja Green Giant Hybrid Arborvitae is a hybrid-cross between (Thuja standishii x plicata)

Back in the mid-nineties when Thuja Green Giant started gaining popularly, most nurseries did not have any big trees to take their cuttings from. The western red cedar had been around for years and it is my theory that thousands of cuttings were taken from Western Red Cedar trees and sold as Thuja Green Giant. This is just my theory, not a comprisery theory, I would not name names if I had any.

At Thuja Gardens we are still taking our cuttings from the trees we planted in 1999, they came from a big propagation nursery in Georgia. Today the Thuja Green Giants we planted in 1999 are only 8 feet wide x 30 feet tall, no way they are going to grow 30 more feet.


I still stand by the fact: Thuja Green Giant trees purchased from Thuja Gardens will grow 6 to 8 feet wide x 25 to 35 feet tall.
