Should I Feed my Endless Summer?
I don't know why, but I didn't winter-cover my ES and thought, surely I killed it. But now new growth is coming up from the base and last years stems are looking dead.
I know ES blooms on both old and new growth...should I wait before trimming the "dead" stems?
What, and when should I feed it? Can I use 'Hollytone'?
Thanks for your help.
