Tips On Tree Care

Certain trees will not live long if a fill of soil is laid over their roots, or if a terrace of blacktop, stone, brick or concrete paving blocks is laid over their feeding roots. Large, valuable trees should be protected with drain tile so that they will get water and air. The bark should be protected from dirt from a fill directly against it. You can buy metal tree wells, 3 to 7 feet across and 1 to 3 feet high, or build a masonry wall.

The wall can be capped with a circle of bricks or a low wall to make an extra seat on the terrace. If you have some surface other than sod or earth around the tree, see that it does not extend as far as the tree's outer feeding roots, and leave a circle of natural soil around the trunk. This can be planted.

Care for your trees as injuries occur rather than wait to call in a tree surgeon and allow a weakened spot to remain untreated. Remove all dead, decayed, diseased or injured bark. Do this by removing the entire limb, or, on a large limb or trunk, dig out the decayed matter, sterilizing and waterproofing the cut surfaces with creosote and liquid tar. White lead or paint are not as good to use as they will not seal when used on damp surfaces. Fill deep wounds with concrete. Use a pruning hook carefully, avoiding bruises.

Evergreens

Evergreen trees and shrubs are more expensive in general than deciduous trees (trees that drop their leaves in winter). But they are worth their cost because of their year-round beauty, hardiness and longevity. Evergreens range from the broadleaved shrubs like rhododendron and laurel to the tall-needled cone-bearing pines and stately spruces.

The giant spruces and firs are most effective as windscreens; the spreading evergreen shrubs are widely used not only because of their attractiveness but also because they can be shaped and trimmed and do well in the shade (such as for foundation planting). Pine is the most commonly known of the evergreens. White pine is noted for its long, soft, light silvery-green needles and rapid attainment of its 60- to 80-foot maturity. Red pine, as well as white pine, is splendid for backgrounds and windbreaks.
