When picking veg for showing yesterday, a farmer type person saw our potato
plot, and said he thinks the potatoes have blight. The plants are yellowing
and dying off, with brown and black spots on the leaves. The same happened
last year, and the potatoes were mostly fine. Is this blight, or are the
plants just dying off (which is what we thought last year)? If it is
blight, what do we do now?

Cheers
