Overview

This native arborvitae hybrid is fast-growing, neat in appearance, and often substituted for Leyland cypress. Left alone, the tree can reach a height of 60’ but is easily kept smaller. Unlike other tree species, ‘Green Giant’ responds well to pruning. It has a naturally narrow spread, to 18’, which makes it useful for smaller gardens and as a screening hedge.

With its sprays of foliage neatly arranged, the tree has a tidy, balanced appearance, and does not mind pruning to keep a desired height and spread.

Characteristics

• Medium size
• Reddish brown bark
• Sprays of fine, medium green, scale-like leaves
• Slight leaf fragrance
• Tolerant of full sun and part shade

Planting Tips

If you plant a ‘Green Giant’, select a spot that has some relief from the very hot afternoon sun and keep a layer of mulch around the trunk and drip line.

Plant this tree as an accent in a location where its height and foliage can be admired, and where its evergreen winter form can provide structure to a garden design. Or use it in a group to make a large hedge, screen or windbreak. Because it puts up with repeated pruning, trees used as a hedge or screen can be planted as close as 7’ apart.

General Care

‘Green Giant’ is generally considered pest- and disease-free, but it may experience the same insect pests and pathogens common to evergreens, including bagworm and scale.

Best practices to prevent infestations include:

• Monitoring the foliage and branches to control any infestations before they become severe
• Minimal and proper pruning cuts to reduce the chance of pathogens entering the tree
• Checking your irrigation system to make sure soil around the tree is not saturated
• Keeping mulch away from the tree’s trunk
• Planting in acidic soil

Because of its dense foliage, any pesticide spraying should be done by professionals to ensure thorough and even coverage.
