My lupin has, I think, got Lupin Anthracnose. The leaves have brown marks and some have shrivelled. I have picked some of the leaves off today with these marks. Any suggestions please? Thank you. Pat

Thank you very much for this website. Very useful. Can’t say we have had much rain but I have been watering from above, so will now concentrate on base of plant.

Not sure if it is but here is the RHS link. See if you think it is a good match for the disease.
