A correction (perhaps)
On reflection, I don't think my post from yesterday makes much sense. I wrote about our potato plants suffering from blight, but it not having been too serious in previous years. Well, blight is serious, and there's no reason to believe that our plants have some sort of special dispensation to contract it but only in a mild form.
So, the suggestion is that what our potato plants have is not blight, but something else. Something that leads to black spots and general yellowing of the leaves, would strike early in the season and yet still allow production of a good quality (and large) crop by the time the plants are lifted later in the year.
A quick skim through Hessayon suggests that what we have is a magnesium deficiency. Photo 161 on the following website is a pretty good example of what our plants look like.
Whatever we've got, it's probably not blight. Either way I'm happy. The potatoes we harvested yesterday tasted nice, and past precedent also suggests that our crop will store well. What else can you want?
