It is the same in central TX. Hot wind, burning sun. My tomatoes are still putting out new tomatoes, except my cherry tomatoes, they have a few green fruit. My heirlooms seem to be ok, one is full of flowers, the others are ok, but no flowers. I started them late. My squash quit putting out fruit, so I’ve pulled them, the cukes were going gang busters, but then just quit, they still have lots of blooms, but no cuke. The okra think this weather is great. The banana peppers are and have been about an inch long, they are not growing longer.
Now that's really interesting. I'm having just the opposite experience here in San Antonio.
Tomatoes have stopped producing new fruit, except for my grape and cherry vareties. In fact, my Celebrity, BHN-444, and Tycoons just shriveled up. So, I've pulled them. These are recommended varieties for our area but they were the first to go belly up.
The indeterminate varieties, for the most part, are still healthy. Those that are not will go under my pruning shears in hopes of saving them for the Fall. I think I'm also going to see what happens when I stick a cutting in the ground.
Cukes are bizarre. The first plantings, Suyo Long and Baby Cucino, have definitely slowed down big time but still produce new fruit. My three Bonnie Bush Hybrids are sprawling and loaded with flowers but have produced only one cucumber. The second plantings of Armenian and Palace King are starting to climb and have already sprouted a few young cucumbers. Getting ready to start seeds for the next round of Suyo Long and Baby Cucinos. I am really satisfied with those two.
Not so satisfied with White Wonder Cucumbers. They are BITTER. Got the seeds free as part of a Burpee anniversary promotion. Googling around I find bitterness is common in the variety and is attributed to heat. That definitely excludes them from a second try.
