Hydrangea Not Blooming for Two Years: Pruning Timing Critical

Two hydrangeas bloomed first year, then nothing for two years. Owner prunes and cares for them.

Most common cause: pruning at wrong time. Hydrangeas flower on old wood; prune in late August after flowering. Fall or spring pruning removes next year’s buds.

Advice: stop pruning for a few years to allow bud set. Fertilize appropriately.
