I have some nice green tomatoes on my vines, but they are not growing or ripening. what can be the problem?

Question

I garden in Georgia and we have had a little rain, but extremely hot temps and high humidity.

Answer 1

The longer the heat lasts, the longer those tomato will continue to hit the pause button. In short, hot weather can delay your tomato crop.
In the South it can help to plant so that your tomatoes will receive morning sun but afternoon shade.
You can add some shade to the plants.
Researchers have found that best yields occur with a shade structure that’s open to the east (no cloth on that side), so the plants can be bathed in morning sun, but shielded from hot afternoon rays. To build one, create a simple frame around tomatoes using wood or row cover hoops, then drape shade cloth (found at garden centers or online) over it. Look for “50 percent” shade cloth, which reduces sunlight by 50 percent and heat by 25 percent
