Should I "top" my sparsely-flowering runner beans?
I know the usual advice is to nip out runner beans when they reach the top of their support. Well, mine have - but the constant rain means they have grown at an alarming rate - but there are very few flowers. I'm tempted to let them just "hang down" in the hope that sunshine will eventually come and more flowers be produced. What do other people think I should do? (They're growing up a wigwam in a large barrel).
