During summer and autumn, climbers will throw out their long new climbing canes. Some will come from the bases of the plants; many will come as secondary or lateral growths from existing canes. The former are usually the better in that they form entirely new sections of the plant. Sometimes, they are so vigorous that they carry no mature growth-buds for many feet of their length-often twelve or fifteen feet before there is any likelihood of any bloom-bearing or climbing laterals.
These climbing canes are very soft, brittle, and easily damaged by wind. They must be secured to supports. They should be tied in an almost vertical position, for if they are drawn down to near the horizontal, in the manner adopted at winter pruning time, they are apt to produce many lateral climbing growths that will give spring blooms in great numbers but of poor size. If the same canes are tied vertically in summer and autumn but almost horizontally in midwinter, they will produce strong bloom-bearing laterals in spring.
Watering, disease control, disbudding, manuring, and possibly covering of
blooms for exhibition will complete the treatment for the remainder of the late
summer and autumn.
