Since the temperature has settled in the 100+ degree range our tomato output has fallen drastically. Most blooms just won't set fruit at these temps. Yet, as an exception to the rule, our Sunmaster and Heatwave plants still have a few tomatoes on them. Two have ripened on Heatwave A (I'm using the A and B designations whenever we have two plants of the same variety) in the last week, and it still has three growing on the vine. Sunmaster B--a plant that we put out in June--has put on a couple of tomatoes as well. That's not many tomatoes, but I'm impressed with any production in this heat.
