What is a safe distance to keep between a tree and my house?

The distance between your home and a tree planting should be determined by the mature width of the tree’s canopy. Trees should be planted at least a distance of 1/2 of their mature canopy width from a home. For example, if a tree’s canopy¬†at maturity is 40 feet wide, it should be planted at least 20 feet from your home.
