Happened overnight and hit one variety worse than the other. We've cut the haulms off the worst hit ones (Ratte, which were the ones also badly attacked by flea beetle and colorado beetle - the other variety Oceania weren't touched by either!). Not really a problem as they are 2nd earlies and fully formed, but they are very close to my toms so I am crossing everything here.
Also it's interesting to note that there were quite a few green spuds sticking out of the soil and starting to sprout. So much for the earthing up. Next year I'm doing it Jandra's way, no earthing up at all, as all they do is just ride up in the soil and have their spuds in the top 6" anyway. It's a complete waste of energy.
