Shade 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.
Velop unhindered and avoid planting ecimens that will outgrow available space, onsider the habit of the trees as well as eir flowers, foliage and berry color, and ant them where their form can be ipreciated. In confined spaces fastigiate olumnar) trees are best, but where space «ds to be filled those with spreading anches are ideal. For small backyards, lect trees with several attractive features tiich can be enjoyed for much of the year, ther than those that have only a ectacular but brief blossoming period, rergreen trees provide form and interest all ar around although many deciduous trees : attractive even when bare.
Trees can affect nearby buildings, sating shade and extracting water from the bsoil, which brings the risk of subsidence. ant large trees away from buildings if issible. The ground under deciduous trees 11 have to be cleared of leaves in the fall, ir this reason, do not position pools or ndboxes under their canopies.
On the other hand there is no point in becoming so sentimental that-decrepit, dangerous or otherwise unsuitable examples are kept even though they interfere with amenities and perhaps with the growth of sturdy young trees. Think long before you remove a tree. Consider well before you plant one. Poor choice or poor location becomes more difficult to remedy with every passing year.
When we speak of shade trees we refer to larger types that either .naturally or through careful pruning may have their lower branches sufficiently high to walk or sit under. They may be evergreen or deciduous. Of the former we usually include only broad-leaved kinds, such as evergreen oaks and magnolias, omitting conifers (needle-leaved kinds) such as pines, spruces, firs and hemlocks. Evergreen shade trees are adaptable for planting in mild climates only. |
