This isn't me getting too overexcited at the first prospects of spring, more that I may have planted my runner beans a bit too early. They're indoors, in 3" pots, but they're about 20-30cm tall already and the roots are beginning to creep out. It seems crazy to repot them though and I'd don't really have room indoors to put them if I do have them in bigger pots. I've got a coldframe that they could go in - although it's small and they're probably too big for that already!
It's surely too early to put them in the ground (although I'm in central London and temperatures are forecast to be 18C by sunday...) but I'm not sure what to do?
