This is my first year growing potatoes. I built a
2 1/2 ft x 6 ft x 3 ft high frame covered by 1/2 wire mesh. I mulched with straw as they grew. Today I took a peek down into the straw and found a grayish blackish layer of what I can only describe as some type of mold :( I started these after the early season rains the plagued the Northeast. Something tells me this is not good.zone 6
