How Big Will Green Giants Get When Planted in a Row for Privacy?
A common request from property owners looking for a row of privacy trees is ‘something that grows fast and dense, but stays medium size’. As a general rule, In nature most things that grow fast will also want to grow big.
When planted alone in the middle of a yard, a Green Giant Arborvitae can grow to be about 50 feet tall and 15 feet wide.
However, the size of the trees ‘within reason’ can be managed through population density. As trees compete for sunlight, nutrition and water, their size will moderate to fit the space.
When Green Giant Arborvitae are planted about 5’ apart, their maximum size will tend to be about 25’ tall x 7’ wide. Since the trees are a skinny tall pyramid shape, they branches will form an impenetrable green wall to about 12-13 feet height. So at that height the tree is only around 5 feet wide. This shape and growth pattern makes them ideal to form a green wall for backyards.
