Broad Bean disaster.
A few weeks ago my block of broad beans (Sutton) was looking fine.
Just as they came into flower blackfly descended right amongst the flowers (looked at sprays but they warn against spraying flowers) and by yesterday there were no viable pods. I have tried cutting back to the roots in the hope of new shoots. Next year I will try removing the tops after a few flowers have opened. -- CTC Right to Ride Rep. for Richmond upon Thames |

You CAN spray if you use a non-toxic one. You won't get those in a garden centre. I use Savona (horticultural liquid soap, available from Tuckers), Green Gardener have some rape-seed oil stuff (sticky, don't spray onto windows), or could can make up a slightly stronger than normal washing-up solution of washing-up liquid with a squirt of methylated spirits. When the blackfly start to hit, soak the plants with infestations using a hand sprayer. Don't worry about the other beans. Repeat as needed. If the ladybirds etc. seem to be controlling the blackfly, don't spray those plants - what you are trying to do is stop the explosive infestation for long enough for the parasites to get a grip. This year, I have had to spray only a few plants only a few times. Regards, Nick Maclaren. |
