| I had one bloom on my plant this year and my wife says I should not cut old stems from last year's growth. Is there a rule of thumb to go by? |
| Hydrangeas flower on new shoots which develop on old wood. So, you can prune your hydrangea down to about 12-18", but you'll want to leave that much old wood so new flowering shoots will have a place to develop. Best wishes with your hydrangea! |
