Here are some of ours chitting and awaiting the warmer soil. My Dad grows lots of potatoes but we like to grow a few, this year we are growing them solely in tyre stacks at the back of the garden rather than taking up space at the allotment best used for other crops. If it's a dry Summer they are more likely to get a watering from the water butts at home more regularly than at the allotment too.
Our organic seed potato choices this year are Arran Victory (maincrop) and the absolute best potato I have ever ever tasted (can you tell I love these); and Cosmos 2nd Earlies. We shall be attending a local Seed Swap event this weekend and may well return with another variety from one of the vendors there.
