|I purchased a blue hydranga 5 or 6 years ago and while the plant is beautiful each year, I have never had so much as a bud on the plant. I've tried cutting back the dead wood in the spring, not cutting it back, etc. Nothing has made a difference. What can I do?|
|Hydrangea macrophylla, the common blue hydrangea, produces flowers on new shoots which develop on old wood. If your plant freezes down to ground level each winter, or if you prune it down each spring, it will never have old wood on which to develop flowering stems. It may never bloom for you. You may want to replace your hydrangea with one of the newer cultivars which bloom on new wood (Endless Summer, for instance).
Best wishes with your garden!
