There is, however, one season for pruning unquestionablypreferable to all others, as far as the welfare of the tree, and the soundness of itsfuture timber, is concerned. It is well known to physiologists and observing gardeners,that when the sap is returning, wounds heal with the greatest rapidity. Hence, inall plants which arc difficult to strike from cuttings, the gardener makes choice of thepoint of a shoot in that particular stage of maturation when the sap is returning; thatis, when the of the shoot is beginning to assume a ligneous character. This, inhardy trees, is uniformly a week or a fortnight after midsummer, and it will be foundthat the wounds made by cutting off branches at that season, or any time within threeweeks after midsummer, will, in the course of four or live weeks, be partly covered witha callosity proceeding from the lips of the wound.
