I planted my runner beans in pots about two weeks back and have them sitting in the spare bedroom window. The point is they are now over 38 cm tall and I'm worried that if I don't plant them out soon they will get too large to support themselves or take over the bedroom..... I have the window open in this room so the temperature is similar to the outside and hope this will help in hardening them off. So the question is should I insert little sticks for them to support themselves with and keep them in till the end of May, or plant them out and pray there is no frost ????
Any advice would be welcome,
