Hi, I have planted 11 x 10 foot rows of potatoes today, it was a hard job, but someone has to do it. :) I have: King Edward, Maris Piper, Charlotte, Pentland Javelin and Duke of York. I've planted them all on the same side and the maincrops are at the back, so that I can replace the earlies with something else when they are lifted. I think you leave them there for 11 or 12 weeks, but I'll check that out, I'll soon know anyway when the greenery starts dying off. I just need to think what else I am going to put in and start with getting it done soon.
