Roots Trees Shrubs: 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 trees shrubs 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.
In many shaded places roots trees shrubs of trees and shrubs pervade the ground. Naturally they take up water. If they are near the surface they are in immediate competition with the grass for moisture, but even the deeper roots trees shrubs absorb moisture that might rise in the ground by capillarity (in the way oil travels up a lamp wick) and be useful to the grass, if the tree and shrub roots trees shrubs did not get it first.
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.
