runner beans leaves are turning black what has caused this



I can't see where you are in britain but from the midlands north there have been patchy frosts that may have caused the problem

In some parts of the UK it was very cold two nights ago with a frost in some areas so if they are outside then that sounds the most likely cause.

We wont be putting our runner beans outside until the end of May.
