Here's a Golden Jubilee that got dark and just rotted on the vine. I've never had this happen before. Looked inside and couldn't see any grubs or anything. Almost thinking too much water, but it doesn't seem likely since I only water twice per week, albeit deeply. Temps for last 3 weeks have been around 100+. Anyway, only fruit that has done this. Rotting seems to have begun at the stem end, not the blossom end. Still green as you can see. Interesting.
