I see other peoples hydrangeas, and they have many blooms, I am envious and I wonder is there any way to promote new flower growth, (I can do without all the leaves that's for sure). Also if anyone knows about the propagation of a hydrangea, I was wondering would the cuttings survive inside all winter long????
First, are you sure it was endless summer and not just a regular mydrangea macrophylla? because i have had some that were miss labelled before, and if it is you may be giving it too much fertilizer and it is producing all foliage and no flowers. yes the cutings will survive inside all winter, just keep them some where a little bit cooler.
