Fruits of the volunteers! I just got a good-sized baby potato from one of my volunteer potato plants! This is great because I've heard some people say they had poor results from their potato volunteers.
But mine are overflowing the box (and I was careful to not overcrowd the plants like I did last year, I re-planted the volunteers when they were little to space them out) already... flowering and even fruiting (I'd never seen potato fruit before last year, but I'm getting them again this year)...
There's 3 different varieties (assuming all 3 varieties I grew last year left volunteers, and I think they did since there were some in all areas of the box), the red one is what I just harvested. I also checked some of the white ones, and there's no harvestable babies yet but there are definitely lots of little potato buds.

So far, no serious blight issues... the weather has been good, sufficient rain but not too damp, lots of hot sunny days. There are leaves getting some suspicious-looking spots, especially on lower leaves, I'm not sure that they're blight though or just something else... But I'm trimming them off the moment I see them and throwing it out... Last year I left the suspicious leaves on, not knowing what they were, wanting to see what happened with them heh... Until they started taking over, and I learned what it was, and was in catch-up panic mode for the rest of the season...
