Thuja Green Giant Care Guide

Watering

Keep the soil consistently moist while your tree is becoming established. Pay particular attention to watering while the tree is still in its 1-gallon container, as smaller containers can dry out more quickly during hot or windy weather.

After planting, water deeply and regularly through the first one to two growing seasons. Once established, Green Giant is quite drought tolerant, though deep watering during extended dry spells will keep the foliage looking its best. A layer of mulch around the root zone can help conserve moisture and moderate soil temperatures.

Sunlight

Green Giant performs best in full sun (at least 6 hours of direct sunlight daily), which produces the densest growth. It will tolerate partial shade, but growth may be thinner and less compact.

Soil

Plant in well-draining soil. Green Giant is adaptable to a wide range of soil types, including clay, loam, and sandy soils, but it will not tolerate waterlogged or constantly soggy conditions, so good drainage is essential.

Fertilizing

Green Giant generally does not require heavy fertilization. Once established, if additional nutrients are needed, use a balanced fertilizer formulated for evergreens in early spring and follow the manufacturer's application instructions.

Pruning

Very little pruning is needed. Green Giant naturally grows in a tidy, conical shape. If desired, lightly trim in late winter or early spring to remove any browned growth or to shape the tree. Avoid cutting back into old, bare wood, as evergreens of this type do not readily regrow from it.
