Over the years I’ve sown my French and Runner Beans at various times. I’ve come to the conclusion that the best time to sow them is 2-3 weeks before you intend to plant them outside. That way they are about 9-12 inches tall and are large enough to survive outside, but haven’t started to curl around each other and everything else in the greenhouse. There is nothing worse that bean plants that are trying to “make out” with each other and not a bamboo cane. Make sure you don’t plant them out until all frost has gone in your area. The slightest bit of frost will kill them immediately. Gavin, who used to be my allotment neighbour (he moved last year and gave me his bench, lovely man), always used to plant his beans out at the beginning of May, and always had to put a second lot in because we’d have a cold night and they’d all died. So this year I’ve sown the following varieties of French Beans: “Cherokee Trail of Tears” and “Cobra” and Runner Beans “Firelight”. I’ll keep you updated on how they grow. However I have now run out of compost so will have to wait until I buy some more compost to finish sowing them all. I’ll get some more in the next couple of days.
