|I have 3 hydragenias 1 blooms with little flower and the other 2 don't at all. Could it be the soil?|
|There are only a few reasons hydrangeas won't bloom. One is lack of sufficient sunshine. 4 hours of morning sun will help your plants bloom. The other, more serious problem is that most garden hydrangeas produce flowers on new shoots which develop on old wood. So, if your hydrangea dies down to ground level each winter, or if you have been pruning everything down to ground level, there won't be any old wood on which new flowering shoots can develop. If your plant dies down to ground level each year, you may want to replace it with a more cold hardy hydrangea, or one that blooms on both old and new wood (Endless Summer, for instance).
Hope this information sheds some light on the problem!
