Q: I have seven Vanilla Strawberry hydrangea shrubs. All have a great abundance of green foliage, but they have no flowers. One is in 60% sun, three are in 30% sun, and three are in 20% sun..
A: Unlike common mophead hydrangeas, panicle hydrangeas like full sun, so shade is definitely a problem for yours. I’d hold off on pruning for a couple of years. This would give them more leaf surface to absorb the energy needed to bloom. If flowers still don’t appear, move them to a sunny spot.
