My bean canes are covered in a black soot like substance. Does any one know what this is? Some were new last year and some vary in age from 3 to 10 years. I want to try and clean them as they look awful. Would Jeyes fluid be O.K. Thanks for any help.
I know you can get some fungal disease or another from canes. I would have thought Jeyes was just the thing to kill off any nastiness.
Could Be from Manure in soil from last year a weak solution of Jays will be OK :)
Typical/normal.
Jeyes/Armillatox - yes. A winter routine before stacking away!
