I had a disastrous crop of beans this autumn. before they could produce more than a few strugglers, they were overtaken with a horrible marking on all the leaves. It was a brown colour, and wouldnt rub off, and sort of raised.
( sorry I dont have pic.. not that savvy yet)
I tried spraying it with pyrethrum..to no avail.
The bed was by that time of year, in part shade, and the weather was wet and rainy.
I am concerned that anything that I plant in there come spring may have a disease as well.
And any ideas if I should treat the soil? I have lime...????
