My winter sown broad beans (Aqua Dulce - sp?) are looking very sorry for themselves. They grew nicely and have been providing beans for a few weeks, but they are now turning black.
I don't know if they are just dying as they've reached the end of their life, or if I have 'chocolate spot' (?) The leaves do look to have large 'spots' which are joining together and are turning black.
The plants that were sown a few months later (Suttons) are looking very green and healthy.
Q - I've cut the dying plants down - should I compost the remains, or burn ??
Thanks
