Excerpt from book: growing naturally in the swamp promise well. In addition, a certain space, say one and one-half by two yards, should, if practicable, be left unpaved around the base of the tree, and this space should be kept open, stirred and fertilized from time to time. AYhere this is not practicable, a smaller space left unpaved may be covered by a grill or iron grating, supported on wooden pegs driven in the ground. Such grills are found in Paris, Berlin, and London (see page 119), and permit of watering the trees. This treatment is, to be sure, applicable only with new plantings, when the trees will adapt themselves to the conditions. Where old established trees are concerned, it is doubtful whether they can be permanently maintained when a tight pavement is placed over their roots. Pruning and Trimming. Next in importance to attention to soil conditions, there is nothing of more value for avoiding and correcting trouble in tree economy than properly applied surgery. There is competition everywhere in the living world, and not only do the individual trees compete with each other for root and air space, water and light, but each leaf, each bud, each shoot competes with its neighbor, although only a limited number can develop. As we have seen, trees prune themselves, i.e., some of the buds and branchlets die every year and are broken off by the wind. This natural pruning is the result of the struggle for existence, i.e., for food and light supply, between the buds or branchlets, and an adjustment in the economy of the tree, keeping the balance between income and expenditure. By reducing the number of mouths to be fed the remaining are belter fed. There is, therefore, not necessarily any apprehension to be had if some twigs and branches die in response to the perfectly normal need of a...
