Chillin' In The Garden
cityfarmer, scab is just ugly bumps and black spots all over your potatoes, but if you like pretty little red new potatoes with your green beans, you'll have to peel them. I've also gotten scab so bad that it was more like black cavities the size of a quarter. And the yield will be greatly reduced if you have too much nitrogen for your potatoes. I've learned to plant potatoes in poor, sandy soils with the addition of ashes from my wood stove. Onions, greens, and curcurbits go into nitrogen rich soils.
