For planting Green Giant Arborvitae, the recommended spacing depends on your goal for the hedge or screen:

• For a dense privacy screen (single row): Space the trees about 5 to 8 feet apart. This spacing allows the trees to grow together to form a thick barrier without overcrowding, promoting good airflow and sunlight exposure

• For a staggered double row privacy screen: Space the rows about 8 to 10 feet apart, with 5 to 8 feet between trees in each row. This creates a fuller, more natural-looking hedge with quicker coverage

• For a windbreak: Plant trees 8 to 12 feet apart to balance wind protection and airflow

• For a hedge or dense barrier: Space trees 5 to 6 feet apart for a uniform, continuous appearance

• Near fences or structures: Keep at least 6 to 8 feet away to avoid root and branch interference with buildings or fences

If you want faster privacy, you can plant them closer, around 4 to 5 feet apart, but this may require more maintenance like regular pruning and can lead to some overcrowding issues over time

. In summary, a good general rule is to plant Green Giant Arborvitae about 6 to 8 feet apart for optimal growth and maintenance balance. Adjust spacing based on whether you want quicker coverage (closer spacing) or larger, healthier trees (wider spacing)
