Not sure if this will help you ...but we plant potatoes each year.. this year things where diffrent in the potatoe world... we grew Kenabec which are white and the Norlands which are Red ones..ours bloomed 3 times?? not sure why, but the did and we never had this happen before... I did Can some of the white ones.. and the red ones cooked just fine.. mashed and fried and all that ok.. but we dug ours on early September.. not sure if that makes a diffrence or not. Not sure why yours are mushie pastie.. some of ours rotted in the ground because of all the rain we have had... not sure if all this will help you or not guess it is my 2 cents worth.
