Hi, I've grown potatoes for the first time this year and, probably a bit stupidly, went for a brand new variety called Sunset which I believe is classed as a second early (I say stupidly because I can't find any cultural information on this specific variety anywhere - even Suttons, who I bought them from, have taken all the information off their web site!) Anyway, what I wondered was when do I dig them up? I put four chitted seed potatoes in one of those potato bags in the last week of April and they romped away and I've now had to tie them to stakes as they were getting so long and flopping onto the path. The problem is, they haven't flowered yet - do you have to wait for this or is flowering used as just a guide to timing?
