I need to learn the intricacies of pruning. I know the general rule that pruning should be done after flowering. In the past I have pruned the shrubs whenever the mood took me and this year I wondered why hardly any flowers appeared and came to the conclusion that last year the shrubs were attacked very badly by Viburnum beetle and because it looked such a mess I gave it a good pruning and obviously cut off most of the stems that would have produced flowers this year. But now I have a big dilemma and can't imagine what the solution might be, because all the new growth is happening on the ends of existing stems, so it seems to me that if I want to prune to keep the size under control, I'm going to lose next years flowers again. Help!
