Tell me more about nipping out broad bean tips
I've never grown broad beans before but mine, sown in March I think, are now
about 8" high with lots of flowers. There's no sign of blackfly on them but I'm sure I've heard something about nipping out the tips being a preventative. What's regarded as the tip? A couple of leaves or the lot above the flowers? What's the purpose? TIA Mary |

The realistic function is to stop them putting energy into growth, so that the flowers set better. The secondary one is to cook and eat the tips. And pinching them out won't encourage blackfly, so there's nothing to lose. You need to leave at least two good clusters of flowers - I tend to pinch out when they have reached 4-5 clusters, and take just the unopened leaves and perhaps the leaves below that. That is partly because that is the right choice for cooking :-) Regards, Nick Maclaren. |

But is there a sound reason, apart from gustatory? I mean, you say pinching won't *encourage* blackfly but might it *discourage* it? Mary Regards, Nick Maclaren. |

I would say yours are far too short yet to pinch out unless you have a smaller variety. The tip is usually a thick succulent looking bunch of leaves above the flowers but some are just a few leaves. |

Maybe so but they do not attack in such numbers I find, having not built up the initial springboard from which to spread. In any case I find that going along and rubbing them out with your fingers seems to finish them off. I wonder if the smell attracts more beneficial insects. -- Rowdens Reservoir Allotments Association www.rraa.moonfruit.com Feed the soil, save the planet |

That has nothing to do with removing the tips, and a great deal to do with eliminating the worst of the initial infestations - you could achieve just the same by leaving the tips and spraying with soft soap. Yes, I have done that test. Since I learnt their life cycle, I have reduced them considerably by spraying my Philadelphus HARD in late spring - they overwinter on that (and, apparently, on Viburnum, but not on mine) and then fly to vetches for the summer. You may be right that crushing them attracts their predators; it is quite plausible, and I have seen no evidence either way. Regards, Nick Maclaren. |

Oh it's a thick succulent bunch alright. Just not tall, can't remember the variety but I don't think it was a dwarf one. Thanks for the info re blackfly. Mary |

Basically, roots and leaves can deliver only a fixed amount of energy; annuals start off by putting that into growth and, only later, into seeds. By removing the auxin (plant hormone) feedback from the growing shoot, you push the plant more strongly into the latter mode. That's the theory, anyway. Regards, Nick Maclaren. |

Yes, I have done that test. Well I have found over many years that if I don't pinch out the tips there is a far greater infestation and this doesn't occur when the tips are pinched out as then there is not such an initial infestation in the first place. I think we shall have to agree to differ. Regards Robert Rowdens Reservoir Allotments Association www.rraa.moonfruit.com Feed the soil, save the planet |

There's no sign of blackfly on them but I'm sure I've heard something about nipping out the tips being a preventative. Last year I didn't bother pinching out the tips of my broad beans. I don't remember having a blackfly infestation (certainly no worse than the year before, when I did pinch the tips). What I did get, because I was lazy about cutting the plants down, was pods on the go from July to October. Not necessarily lots, but it was nice to be able to get a few pods to add to the mixed veg for dinner! -- Linz Wet Yorks Hello Linz, Yes, I'm looking forward to having our own. I rarely buy them because there's so much waste (although it's lovely to se the beans in their nest). I'm wondering if blackfly infestation is linked to latitude, so far there's been advice/experience from the far south, East Anglia and you - the closest to me. I think I'll stop worrying about it. Pinch out few tops to see how they taste and, perhaps - your mention of the word 'lazy' is significant! - keep a record of the effects. But I'll probably lose it or not have a pencil to hand when I remember or .... Sometimes Life seems too short for such analysis. Mary |
