I live inland in an open spot and two weeks ago we had a sudden hard frost. Now many of my plants are frost damaged and I'm not sure how best to treat them. I've read that they should and shouldn't be pruned, but as they are different plants and have suffered damage to different extents I'd like a bit of advice. The damaged plants are acers damaged to varying degrees, hydrangeas, the tops of box topiary, many leaves and flowers on my wisteria and some dahlias I'd planted out but covered with plastic bottles. some of the dahlias look really frazzled but others it's only on a few leaves. I do have back up dahlias in the greenhouse so wondering whether to dig up the damaged ones and replace. Last winter I also got a magnolia red lucky that had started to bud and leaf but all have been damaged. Will the white plant die now? Will I get any flowers? I know frost damage is a common problem so hoping for some reassuring advice. Absolutely gutted, I can tell you.
