Q: I have a winter flowering jasmine, growing profusely on a 3m-high north-facing wall. For most of its six years, it has produced an abundance of flowers, from early November until March. During the recent summer, I took a lot of its stems, which had bunched at about 2m, and gently stretched them out along a series of horizontal wires. This November I can only see a handful of flowers (less than 10). Did my gentle summer manipulation cause this drop in flowers and if so, how? CD, Co Dublin
