Soooo I have 50 gazillion Sweet 100's on the vine, and they're all "stuck" at orange. I don't think it's water or sun. I've been semi-sporadic with feeding -- is there maybe a nutrient of some sort they're missing?
How do they taste?
I have LOTS of green tomatoes at the moment. I don't think they are going to ripen. What makes the tomato fruit ripen once it's large enough? With 6 plants, all that went into the ground mid to late-Feb, and they are all short DTM, what gives?
I have picked just a few, very few, just as they began to blush then ripened on the counter. All have been very tasty, two BER toms.
The Sweet 100's taste NOT SWEET. :) They're definitely not ripe.
My Huskies are ripening fine, and I've had a few Celebrities and Romas. The Sweet 100's are in a different spot, though, so technically the soil could be different.
Found a simple explanation from Purdue University that I thought might help.
I've also read that once fruit sets that watering should be decreased because our extreme heat my cause the fruit to burst/split. Something to do with the plants pumping so much water to fruit that the skin cannot keep pace (defense mechanism or some such, I cannot find the book quote exactly)
