is temperature the main reason my tomato plants are not producing tomatos. My Cherry tomatoes are doing good but right next to them but my beefsteaks are blooming but no fruit.
Difficult to say; this could be due to a multitude of possible factors - but when plants (any type) produce a lot of foliage but little fruit, the main culprit is too much Nitrogen in the soil. You could also have a lack of bees, i.e., poor pollination. Tomatoes are native to South America and love heat, so I doubt if the temperature is a problem. Also "little tomatoes, little problems; big tomatoes, big problems...." -- it's absolutely true that cherry tomatoes have far less growing problems than the larger varieties.
