I planted out one set runner beans last week and the runner bean leaves are changing colour. I'm concerned if it is some fungal disease. The seeds were collected from last year’s crop and stored in a dry place.
The same changes can now also been seen on one of the plants on the other side of the veg plot where I had planted some more runner beans from a different seed. These were raised from seed and grown indoors and planted out 2 weeks ago
I would appreciate any help.
thanks in advance
