I had the same issue, they sat there for a month, not kidding, and then, one day I saw a little pink on a cherry tomato and it was contagious and then all my maters ripened at the same time! My advice is to just be patient! It won't be long.

To a certain extent, it is the heat. However, the tomatoes also have to grow for a long while before they go from red to green. Look at the attached link of a ripening Big Beef tomato and note how long it takes it to go from green to the red breaker stage.

I do think that the plants go into survival mode when it is this hot and put a lot of energy into survival and that might slow down ripening a bit.

So, have that big glass of iced tea, relax, maybe even take a little nap and dream of ripe tomatoes. They'll ripen soon, I hope, and put an end to the torture of waiting for them.

That first one takes forever it seems. Then they all come fast after that. I know a lot of it is it just seems like a long time. But I also keep decent records some years and try to mark down when I notice first fruit set on a plant. And then have marked one down that is easy to keep track of set in late August on the same plant. It usually ripens a lot faster than the one set early. I think there are several reasons. The plant is mature. So more of the nutrients can go to making fruit rather than growing plant. Yes the plants still grow but they also have a lot more foliage for photosythenisis. And like Dawn said during this time it takes a lot of the available resources just to keep it alive. I have picked 3 fruit so far. All smaller than I hope the later ones from this plant will be. I also noticed a Spudakee starting to blush some last night. I will check the date I first saw this fruit. Know it has been awhile. I expect the later fruit from this plant to be 3-5 ounces bigger. In my opinion stress causing a fruit to either ripen slow or prematurely. What makes the difference I'm not sure but have seen both happen. Jay
