Thuja plicata

Giant (Western) Arborvitae

Planting:

For hedges, set plants 6 to 8 feet apart. For specimen plants, space 10 to 15 feet apart. Performs best in a moist and fertile but well-drained soil, either acid and alkaline in nature. The most vigorous growth will occur in full sun, however plants will tolerate light shade.

Maintenance:

Water regularly during hot, dry periods and add a summer mulch to maintain soil moisture. Prune as needed in early spring and midsummer to maintain the desired height.

Zones:

Zones 5-7.
