"TREE STAKE 78""" 7/8" x 1.75" x 78" Tree Stake. Tree stakes have a pointed end that can pierce the ground without causing harm to the soil or grass. The stakes act as a protector to the growing tree, providing it with a stable base that increases healthy growth. The stakes also provide the grower the ability to control where the tree grows. Trees that lean because of top-heavy branches have a larger risk of collapse and damage, which can be prevented with fortifying tree stakes. Some stakes include ties which help improve stability, but if the stake does not include an attached tie it is recommended to use individually purchased ties.
