100 degrees in the shade, no rain, and everything is drying up. Are your tomatoes still "making"? If they are, keep them watered and mulched, and feed them occasionally.
The fruit doesn't set in the warm night temperatures over 70 degrees. Even Blossom Set doesn't help until cooler weather.
If they aren't ripening, the plant doesn't have enough strength to ripen the fruit. I pick mine at the first touch of color, or the varmints will eat them.
I let them ripen inside, in a bright window.
If your plants look bad, cut them off at the ground and replace them with new plants. Keep the new transplants protected with shingles or row cover until they become established.
If you have a problem with nematodes, dry till your garden area before planting. It will help to eliminate them.
To help your lawn during this heat, raise your mower blade 2-3 inches for St. Augustine and 1-2 inches for Bermuda and Zoysia.
Watch for Grub worms in the lawn and use an approved insecticide. An application of an approved insecticide and fungicide or pecan trees will prevent foliage damage.
When planting new fall plants, use row cover to keep them insects off plants and it will help to shade them. Start seed flats of broccoli, cauliflower and other cool season plants.
Tip: Keep dead-heading the annuals and perennials. Spray with a foliar feed in the cool of the evening.
