Herbaceous perennial plugs
Apologies if this has been covered before.
We bought a collection of hp plugs, they were cheap we only paid postage! They didn't do very well and we lost most of them, there are a few survivors that look fairly robust, penstemons and geums. Should we plant them out now, or would it be better to keep them in pots, bring them in over the winter and plant out in the spring?
