I neglected to properly prepare a Wisteria and Autumn Clematis for winter this past season and it doesn't look like they are coming back. I think part of the problem was that I had them in pots that weren't protective enough for the cold, so I've upgraded to some frost proof planters for this season. That said, I have a ton of soil that I was wondering if I could repurpose to plant some new climbers for this year. A neighbor mentioned that it would be fine as long as I added some fertilizer and mulch. Could this possibly work?
Thanks in advance.
