I think your solution will have to be found locally, Janyss471. Most of us have never dealt with zone 3 growing, things that will work with no problem in my zone 8a garden with really hot summers wouldn't work for you at all. Are you on FaceBook? I'm on mainly for all of the wonderful gardening groups! If I were you I'd ask this question on a local gardening group, might be able to come up with something those of us in the lower 48 would never think of.
