I am on my second year of growing hydrangeas. There are books out there that tell you which ones flower on this years growth vs last years growth. My only problem is that we have so many different ones, I cannot identify them in the early spring when they are starting new growth.
This year I have experimented with propegating them. I have found that layering works well, and wounding a stem and placing it in a growing medium works with some but not all varieties. We got the propegating kit from Lee Valley thay allows you to start a new plant from a non-flowering stem.
As far as the pruning goes. I waited until mid spring to see which stems were alive and which were dead before I started cutting. I think that helped, and got flowers on al but one of a dozen shrubs.
Does anybody know if they will grow indoors over the winter? Two of the propegated plants are in pots, and have not been planted. I am wondering if it is too late to put them in the ground or if I should bring them inside?
