Most tomato varieties don't like evening temperatures above 75 degrees. Added to that, most tomato flowers will not set if the temperatures are below 55 degrees or above 92 degrees.
Given that our temperatures have been well above 92 degrees for most of the last 3 months and our evening temperatures rarely fell below 83 degrees, my tomatoes have not been very prolific this summer. In fact, they have essentially gone dormant.
However, Tomato weather may be around the corner in North Texas.
Starting today, the temperatures will be just right for our tomato plants. All week long, the high temperatures are forecasted to be between 86 and 92 degrees. More importantly, the evening lows are forecasted to be between 64 and 68 degrees. That's just right.
If the hot, hot temperatures don't return any time soon, maybe we'll get some nice big ripe tomatoes on our plants in September, October, and November before the season is over.
