During the heat wave, I went out in the garden every evening close to dusk and soaked all the vegetables. That gave them overnight to absorb water, which would otherwise evaporate and dry out the ground during the day.

Don't know if that will help you, but I'm going to have a ton of tomatoes and peppers. The broccoli has been good. Corn & Eggplant looks good as well.

It also doesn't hurt that the next door neighbors shot or trapped the groundhogs that lived under their garden shed (which no longer stands), so I don't have any critters chewing on the plants!
