About this tree

Thuja Green Giant rockets up to 30-50 ft. tall and 12-15 ft. wide, forming a dense emerald wall in just a few seasons. It's one of the fastest-growing evergreens available, thriving in USDA zones 5-8 with a vigorous, pyramidal habit. Naturally deer-resistant, drought-tolerant once established, and disease-free, it needs almost no maintenance to stay lush year-round. Plant a row 5-6 ft. apart for a living privacy screen, windbreak, or property-line border.

Full planting & care

Planting+

Choose a spot with full sun or partial sun and adaptable, well drained soil. Dig a hole twice as wide as the root ball and just as deep, set the tree so the top of the root ball is level with the ground, backfill, and water in well. Space about 5 ft. - 6 ft. from other plants.

Watering+

Water deeply about once a week while it establishes, then ease off as roots take hold.

Fertilizing+

Feed in early spring with a balanced slow-release fertilizer formulated for trees and shrubs. A second light feeding in early summer supports vigorous growth. Avoid fertilizing late in the season.

Pruning+

Prune lightly in late winter to shape; for a formal hedge, trim the sides and top once or twice through the growing season to keep it dense.

Frequently asked questions

How far apart should I plant Green Giants for a privacy hedge?+

Space them 5-6 ft. apart center-to-center for a solid screen. For a faster fill or a thicker windbreak, you can tighten to 4 ft.

How fast will they actually grow?+

In full sun with adequate water, expect 2-3 ft. of new growth per year once established, reaching screening height within just a few seasons.

Will deer eat them?+

Green Giant is one of the most deer-resistant arborvitae varieties. Deer browsing is rare, especially compared to Emerald Green.

What zones do they grow in?+

They are hardy and reliable across USDA zones 5 through 8.
