Tree-Guards
These, in some form, are requisite for placing round all newly-planted trees in public streets, avenues, &c., where it is often necessary to provide some protection for the stem for several years. Besides protecting trees, the Guards act as an efficient support against injury from the wind after transplanting. The most substantial and best-formed, though rather expensive, Tree-guards, are those of circular shape, made of iron, the lower part, which is fixed into the ground, being wider in diameter than that which surrounds the tree stem higher up. A common form of Tree-guard consists of three upright wooden posts, placed in a triangular shape, and fixed with pieces of wood at an equal distance from each other at the top. The kind of Guard which causes least injury to the roots is, of course, preferable; the tree should always be tied at the top with cord, so that it cannot possibly come in contact with any part of the Guard and be injured. For protecting the bark of trees planted in streets from being cut by mischievous individuals, ordinary wire netting, of fine mesh, may be tied round the stems when the trees are first planted.
