When hydrangeas don’t bloom (all types of hydrangeas), it’s almost always due to one or more of the following reasons.
1. You pruned at the wrong time.
2. Your hydrangea isn’t getting enough sun.
3. The flower buds were killed by a late winter freeze.
4. Your hydrangea doesn’t like where it’s growing.
5. Your hydrangea hasn’t bloomed yet this year, but it will.
good thing it is not candle talk, we’d be talkin about cuttin the wick
Add a #6: too much Nitrogen fertilizer applied.
Fertilizer formula:
Nitrogen - Phosphorous - Potash
00-00-00 on packages.
Nitrogen = leaf growth,
Phosphorous = roots and flowers,
Potash = stem strength and disease resistance.
