Help a Tree - Remove Grass
Don't let grass grow beneath your trees. Grass competes fiercely for available water and will slow the growth of trees, especially newly planted ones. For instance, if the growth of a tree is reduced by 20 percent for one year because of grass competition, the growth automatically is 20 percent less during the second year's growth. Grass competition alone reduces tree and shrub growth by as much as 50 percent.
