Hi, looking for some advice please. I have had my allotment for 5 years and followed a crop rotation plan, adding manure and compost. Each year my potatoes have looked good when growing and a good size when dug up etc. They have stored well in sacks. Problem is each year they have gone mushy when boiling and have had a dry powdery taste. I have tried varies types including Desiree, Arran Pilot, King Edward, to mention a few. I have the plot ready for the end of March!
I have read lack of moisture in early growing could be a cause, but not 5 years running, and I water if I think things are dry.
Any advice on a potato variety to try or a soil addition please?
Thanks.
