| Maintenance | (Pruning group 3 or C) Be ruthless here! Ignore the fat buds you see further up the stem, grit your teeth and cut back to a height of roughly 8"-12" (this should include 2 strong sets of buds. See diagram). Do this and you will be rewarded by the emergence of vigorous new shoots from the base which will result in a nice, full, multi-stemmed plant loaded with flowers. As the shoots grow you will of course want to spread them out so as to make the most of the display. Sometimes the plants are obliging and train themselves, but most often they need a firm guiding hand (www.clematisnursery.com) |
