I really don’t think taters will do well in shade, but I could be wrong. Chives will grow almost in any shade. I have also grown lettuce in shade.
I should also mention that the soil is quite poor up there. It tills up beautifully, but it’s got no oomph for growing stuff.
I plant it just because I’ll lose use of that patch if I give it up, and I have too much time involved in reclaiming it from the weeds that took it over. Russian thistle, gorse, vetch, bindweed, they will grow there no problem. Anything I like, not so much. < BG >
