Allotments 4 All

We have just finished eating our potatoes that were stored. They have been amazing.Nadine came top then Sante. Maris Piper were ok but towards the end of the sack we started to get some dark patches that were only noticable after cutting the potato up. If cooked then the dark area was very hard.(As ower Tone had to get that one he felt that he had to complain). The other parts of them were ok. can anyone shed any light on this problem

I had a few like that Shirl, I think it was the weather being very mild in Oct/Nov and they tatties not staying cold in the sheds.  ???     ;D ;D ;D

Or frost had gotten to them if they were at the bottom and on the ground
