My potato patch has something that looks like fingers growing up out of the soil. First time I saw these 3 weeks ago it looked like a hand burred in the soil with black fingers. There are about 90 to 100 of these fingers in the potato patch. They look like wood with a long wooden root that goes down deep into the soil. Most grow in groups of 3, 4, 5, and 6. They were not there when I planted the potatoes 3 months ago. Now they look like dead wooden fingers with dead wooden roots, they break like dead sticks.
I have potatoes. I harvested 2 and we had them for dinner. I planted Kinnebec.
