Species Shrubs Trees: Grass, growing in the shade of trees and shrubs, has to compete with them for food as well as moisture. Relieve the pressure of this competition by providing for the needs of the trees and shrubs as •well as the grass. Fertilize the lawn regularly and also the trees and shrubs. So far as possible, place the fertilizer intended especially for the trees and shrubs deep in the soil so that their roots are encouraged to strike downward. This may be done by using the method described below. Fertilizer intended primarily for the grass is applied at the surface.
Trees that retain their foilage all year are invaluable as screens, as background for trees and shrubs that flower before they leaf, as windbreaks and for providing a feeling of solidity and permanence. They include a wide variety of sizes, from forest giants to kinds little bigger than shrubs.
