When days hit 85°F to 90°F and nights hover above 75°F, tomato flowers often fail to pollinate, then drop — which in turn puts new fruit production on hold. The longer the heat lasts, the longer those tomato flowers will continue to hit the pause button. In short, hot weather can delay your tomato crop.
…and I have also learned something about “Determinate” and “Indeterminate” tomatoes. Indeterminate tomatoes grow out of control unless you prune them, and I have Indeterminate ones, so the giant tomato cage I made from a 4×8 section of screen fencing, cut and bent into a square, is a good thing except that I didn’t prune anything. And now the San Marinzano’s have grown up and out of it, and being that are kind of a one-shot tomato – they fruit-up and the plant dies – and with the heat the plant is now brown and crispy. Buh-bye! Anyhow we got a couple colanders of fruit off them and made some sauce, and that is what they are for.
Meanwhile the indeterminate cherry tomato plant has spread out to cover most of the planter-bed, and the small cage that “housed” it is invisible underneath the tangled and twisted vines – and it’s still producing so it’s a hot-climate pant. Maybe next year I’ll try a Determinate plant and get a second-season of growth and fruit (after a second planting), instead of having this wild and wooly, raggedy tangle of vine hanging about all summer long.
Meanwhile this morning dawned with a pink cast to the sky as the sun rose, still a warm 80° at 6:00AM with night time temps barely breaking into the upper 70’s, but the promise of cooler days ahead. Happy Labor Day and God Bless and keep-safe the people of the Hurricane, in Texas and the Gulf Coast.
