We love our lilac shrubs with their exemplary fragrance in May. But almost any lilac that has not been pruned for two years or more is likely to have several trunks, some older than others, and a brood of basal shoots ("suckers") around its base. And as it blooms on branch tips, we might find most flowers up high, out of optimal sniffing range. Pruning to meet these challenges can be a different approach than with many other flowering shrubs.
It's summer! Things are planted and blooming, you want to be outside in the nice weather, and you're keeping up proper watering practices, of course. So proper, in fact, that some plants have gone a little crazy and need pruning!
