Hope anybody can offer some suggestions here. I'm in southern DE, btw.

I just moved into a very small house with no basement, garage or shed. I do have a screened-in porch, but it's basically open to the elements. I have practically no space to overwinter anything in my house.

Is there a way to overwinter tender potted/container-grown plants (e.g. agapanthus) outside? Perhaps wrap or mulch them somehow and place them along a south-facing outside wall?
