have had 2 white hydrangeas for about 8 years. they are still green and bushy but are not producing many blooms.
when I first had them they were abundant, what can I do to get them blooming again?

Are you cutting htem back at all? If so you may be cutting off the flowering parts. Only prune them very lightly (a few inches) in early spring.

Have you pruned them at all, and if so, when? Are they mophead varieties?
