TREES ALSO NEED DOCTORING

SPRAYING has become increasingly necessary because of the decline in the number of birds and the accidental importation of foreign insea ta. Best results are obtained with mist spray.

WHERE valuable trees have developed decayed areas in their trunks, surgery may be advisable. After removing rotted area, parallel bracing rods are necessary to keep the cavity walls rigid.

A long, weak limb, like the one on this oak tree, should be supported by.cabling or it may be lost. The cable must be anchored in a heavy branch. TREES, like people,

living, breathing things, dependent on food, water and air for life. And just as human beings get sick and need a doctor's care, so do trees. For, sturdy as a shade tree may appear, it is subject to an un- limited number of diseases, blights, insect at- tacks and inherent weaknesses that may cause serious trouble.

And with trees there always is a tendency to delay corrective care until the situation is dif-

or

cult to remedy. On this page are a few pre- ventive measures for the guidance of the

leafy friend home owner with only one with many.

Although trees cannot talk, they do ask for help. The signs are: yellow or brown leaves. Undersized or sparse follage. Tips of branches. dying back. Trees full of dead branches, Buda undersized. Short annual twig growth.

Before the frost strikes is a good time to

supply "medicine" or "operate." But an ounce of prevention is more beneficial.

There are five special "Don'ts" for keeping trees healthy:

r.

Don't bump with lawnmower. Don't white- wash trunks. Don't strip off foliage. Don't burn autumn leaves-let them decompose where they fall. Don't salt ground in vicinity of trees, not evon to melt ice.

SECTIONAL Joints are installed both horizontally and vertically to give the concrete filling flexi- bility. A disinfectant and waterproof dressing inside cavity will protect the wood from decaying.

•

USE three cuts in removing limb. First, make undercut 2 feet from trunk. A little farther out-make overcut. Then saw oft stump flush with trunk.

POLE-BAW is offective for tree pruning, which keeps trees, attractive and eliminates dead branches that are breeding places for Invouta and dimerFOR.

THE CONCRETE is moulded into place and filled to the level of the saywood. The surface of the All- ing, is also waterproofed. In time the bark will roll in from the sides of tree, covering the filing
