Here are some easy tips for how to grow Green Giant Arborvitae plants: Dig a hole 2 times the width of the root ball. Till down to 10 in. deep. Add 1 part peat moss to 4 parts soil. Set the shrub so the root ball sits 1-2 in. above soil level. The planting hole should have slanting sides, so the soil does not collapse on the center. Tamp down the backfill to get rid of air pockets. Water deeply and thoroughly. Mulch to retain moisture.
Pronunciation: are-burr-VEE-tie or are-burr-VIE-tee
Description: These fast-growing (3 ft. a year) evergreen shrubs reach 50-60 ft. tall and 12-20 ft. wide. They have an attractive pyramid shape. The flat sprays of dense green foliage darken to a rich bronze in winter. The cinnamon-red bark makes a nice contrast. Green Giant Arborvitae is a cross between Western Red Cedar and Japanese Arborvitae.
Propagation: Semi-hardwood cuttings or seed
USDA Hardiness Zones: 5-7
Companion Plants: Place Green Giant Arborvitae 5-6 ft. apart for a fast privacy screen; otherwise, set shrubs 10-15 ft. apart.
Fertilizer: At time of planting, use a starter fertilizer such as 20-20-20 to encourage root growth. Check with your nurseryman to find the correct water-soluble feed and follow package directions.
Sun/Light Needs: Full sun to part shade
Maintenance: If foliage color, annual growth, or general condition is poor, consult your nurseryman. Otherwise, low care and little to no pruning is needed.
Display/Uses: Screen, hedge, or windbreak
Wildlife: Deer resistant
Note: In the first year after planting, shrubs need special watering so the root ball does not dry out. Water every 3 days in summer, 1-2 times weekly otherwise. To protect shrubs in winter, wrap with burlap to avoid drying from wind.
