Can anyone tell me why my broad beans look slightly yellow and sickly? They had a bad attack of blackfly which I've just about got rid of - would this have caused it? All the other beans on the allotment look really green and healthy. If I ask them what they do to theirs, they don't seem to do anything different? Is it to do with the variety (Bunyards exhibition) or watering perhaps. I haven't got a big crop either, but the few that we've had have been lovely.
1 plant in november this will nearly stop black fly
2 nip out the plant tops when the hieght you want
3 stawry compost around the plants helps to keep plants damp longer
4 spray flowers with a fine spray
when you see the leaves going yellow again try epsom salts in with your water and water the hole plant from the top
when you have black fly again try this put two fags in a glass bottle (about 1 litre) fill with near hot water and leave for a couple of days mix half liquid with equal parts water then add washing up liquid.
then you can spray any of your plants that have greenfly blackfly. ants on fruit trees(trunk stops them climbing )
