Hello,
Black fly have also attacked my broad beans – I just couldn’t water them enough being on an allotment (no hosepipes), so have to be philosophical. I still managed a good enough crop.
But my question is, can I put the spent bean plants, with their black fly on, into the compost? And should i leave the roots in the soil to die back there (thus providing nitrogen??) or dig them up and put into compost heap. Or just compost the roots but destroy the black fly covered plants?
thanks so much,
Daisy
