Light trimming, however, may usually be done in summer with impunity. For pruning into live parts it is better to wait until the foHage has withered, when the food contents of the leaves have been withdrawn into the trunk and become available for the unfolding of the next year's buds. The cold winter makes prun- ^ , , , ing an uncomfortable operation, Fig 20 — English shears , , , r and the results are therefore hazardous and less efficient. It is, in addition, physiologically imdesirable, except on mild days, as, owing to the uneven expansion of bark and wood under the influence of frost, the wood is apt to shrink away from the bark, and a consider- able portion of the cambium may be killed, rendering the healing process more difficult. For the choice of early spring (March or April) it is said that then the healing process of the wounds sets in at once, or at least sooner than when made in the fall, and the dan- ger of fungus infection is reduced. But as a matter of fact it is generaEy believed that the season has not any appreciable influence on the healing of the wound, provided the pruning is properly done, which means also proper protection of the wound. Large wounds especially are best made in fall or early winter (October, November, and December in the Northern States) rather than in spring. In winter the bark adheres firmly and the wood is dry so that the paint or tar can be more readily.
