Shrubs. Ornamental flowering shrubs may be pruned at anyseason of the year if no consideration is given to the question offlower production. Wounds made by pruning will heal, however,better during the growing season. Late summer pruning will some-times encourage a new and vigorous growth which does not thoroughlyripen during the late summer and fall months, and is consequentlyexposed to the danger of winter-killing. Late summer pruning shouldaccordingly not be practised especially on semi-hardy plants. Duringwet seasons, and when plants are over-supplied with food, summerpruning may be resorted to, in order to restrain succulent and weakgrowth. |
