This week Jim Downer, one of my colleagues at The Garden Professors blog, posted an article about how garden plants (and really most plants including crops) respond to very high temperatures. Fortunately, here in the Southeast we have not seem extremely high temperatures here very often this year, but the summer is not over so you might be interested in reading about how you can help your plants survive any scorching conditions that do occur. You can read his note at https://gardenprofessors.com/im-hot-so-are-my-plants/. I also post about weather and gardens there on the last week of every month.
