I think you’re done. Pick and toss the smaller fruit, leaving only the full sized ones. If there are good fruits grown, but not ripe, you can try spraying the mildew with safer soap, and see if the fruit will ripen in the meantime. Or you can pick everything, keeping what may ripen a bit on the wildowsill, or be used green in pickles or whatnot, and celebrate your successes this year. I’d probably go with the latter, and a glass of hard cider.

I think it’s closer to the last scenario. How many leaves does a plant need to keep growing fruit I wonder? If there are 2-3 clean leaves is it worth leaving it?

Thanks!
