broad beans and blackfly
I'm growing broad beans for the first time this year and they seem quite
happy so far -- the blossoms are just beginning to open. My question is about "pinching out" and blackfly. I've seen numerous references to this but haven't been able to figure out what exactly is meant. What I've been able to gather is that when the pods begin to appear, you are supposed to pinch off the top couple inches of growth on the main stem. Is this right? What exactly does this accomplish? |

This helps them to set, and helps to prevent the beans getting too tall and breaking in wind. It is claimed to reduce blackfly, but I don't believe it. You can cook the tops pinched off, like spinach, and they are quite good. Regards, Nick Maclaren. |

The theory is that the blackfly are attracted to the young tender growth at the top. -- Kay |

Flood the areas of the plants they are infesting, and repeat as necessary (after 48 hours, if need be). The blackfly shrivel up and die, within hours in this weather. Regards, Nick Maclaren. |

Just as a matter of curiosity, I wonder if anyone has ever tried Saponaria officinalis for this purpose? -- Sacha www.hillhousenursery.co.uk South Devon (email address on website) |
