When to prune Forever and Ever to ground
I have 2 forever and ever "White out" hydrangeas in containers that I have overwintered for about 4 years now. This past summer they were leggy and just not as beautiful as they have been in the past. I am thinking about cutting them all the way down to give them a fresh start. Is this advisable? (I don't want to kill them) and when is the best time to do this? Thanks!
