After planting, staking, where necessary, should be attended to. It is not necessary to stake every tree that is planted. When it is sturdy, with a well-balanced head and set of roots, and the position is not exposed to rough winds, staking is needless. If, however, the stem is weak or the roots are mostly on one side, not spread round the tree, or the position is very exposed, staking for a time will be necessary. In the case of young trees little difficulty will be experienced, as good straight stakes can be easily got. As a rule, one stake is quite enough for a tree, and that should be driven in as close as possible to the trunk without injuring it or the roots. To the stake the tree should be secured with wire or stout tar string, using thin cushions of felt, leather, or old hose-pipe to keep the wire or string from cutting into the bark. Allow a little room between the stem and stake for growth. Two or three ties are usually sufficient, and these should be examined and loosened once or twice a year until the stakes can be dispensed with. The habit of putting in stakes in such a way that they cross the trunk, and that when the wind blows there is sufficient play for the stem and the stake to rub against each other, is a bad one, the chafing often causing serious wounds. In exposed situations, or when there is danger of the tree rocking about and becoming loose at the collar, put in three stakes in the form of a triangle, the stem fitting in the space left between the three stakes at the top, while the bottoms of the stakes extend some 2 or 3 feet from the tree. For this purpose wires fastened to stakes driven in the ground are useful, and neater than stout stakes. When wires are used, however, take care to provide a good soft pad between the tree and the wire. For trees with large heads, or those not well furnished with roots, this way of staking will be found very useful. When inserting stakes they should be properly sharpened for the sake of straight driving. The staking of trees which have the lower parts of their trunks straight and their leaders crooked differs from other staking, as the stakes should not be driven into the ground, but tied firmly to the trunk below the bend, the leader being then drawn to the stake. In all cases, however, where staking is done the stakes should be removed as soon as the trees are able to do without them. A stake is not beautiful. There is always the chance of the tying material being left a little too long without examination, and therefore it cuts into the bark. Ties also harbour insects.
