Q: I planted two Limelight hydrangeas last year. They look very healthy but will they bloom if I didn’t prune them this spring?
A: They will be fine and will bloom in late summer. ‘Limelight’ is a panicle hydrangea. It can tolerate full sun and produces large, light green blooms which turn pink as summer ends. In my opinion there is no need to prune ‘Limelight’ unless it gets too big for its space. That said, if you want huge flowers on a short plant you can prune it to 18 inches in early spring. This hydrangea blooms on new wood, unlike the blue/pink common hydrangeas, which must be pruned in mid-summer if you expect blooms the next year.
