We have been improving the soil here for over 30 years and also add a commercial palletized fertilizer when we spade the patch. We have room to spare so I plant the tators 30’ apart and try to hill 3 times after they come up. We have the potato blight in the soil but try to grow the crop fast before it hits. The hills we have dug had good results
Soil improvement is the never-ending chore with respect to gardens, I guess. So far we don’t get near enough to add to our gardens, which is why I had big hopes for the sunfloweres and amaranth.
I am thinking about planting double the wheat and rye this year to make up for the small amount of compost this summer.
