How to Winter Rooting Hydrangeas??
I have several hydrangeas that I've started to root in pots about a month ago. I have the pots covered with clear plastic bags and they are doing just fine. My question is if I bury the pots in the ground along side the house for the winter, should I remove the plastic or leave it on? Would it be better to remove from pots and plant directly in the ground? I assume, too, that either way, mulching with leaves would be a good thing.
We'll be gone for the winter so don't want to leave them inside or in the garage unattended for three months because I'm afraid they would dry out. Any advice would be helpful. Thanks.
