Description
"Summer Pruning should be performed while the shoots are yet young and succulent, so that they may be in most cases be nipped off with the thumb-nail. It is very necessary in the case of trees trained to a flat surface, as a wall or espalier rail, to prevent undue crowding. In some cases, as, for example, with peaches, the superfluous shoots are wholly removed, and certain selected shoots reserved to supply bearing wood for the next year." — Encyclopedia Britannica, 1893
