Endless Summer Hydrangeas: How to prune them without killing next year's blooms
By My Yard Editorial Team · 7/28/2026
The Quick Answer
Endless Summer blooms on both old and new wood, so prune only dead stems in early spring once buds swell. Cutting everything to the ground in fall costs you the first and best flush.
The Witty Breakdown
If your hydrangea leafs out beautifully and never flowers, you almost certainly pruned it at the wrong time — or a late frost did it for you.
Bloom color is soil chemistry: acidic soil gives blue, alkaline gives pink. Aluminum sulfate for blue, lime for pink.
Step-by-Step Fix
- 1
Wait until spring buds swell so you can see what's actually dead.
- 2
Cut dead stems back to the first live bud, no lower.
- 3
Deadhead spent blooms through summer to encourage rebloom.
- 4
Mulch and water consistently — they wilt dramatically and dislike drying out.
Pro-Tip / Do Not Do This
Don't 'clean up' hydrangeas in the fall. That tidy autumn haircut is why you had no flowers in June.
