Nearly any type can grow in warm temps; however, since corn has very shallow roots, it needs lots of water during its active growth, especially in temps as high as you are experiencing. Typically, the garden needs about an inch or so of water each week. It is a good idea to water deeply (for about 20 min. or so) every other day or two, depending on the weather. Once temps reach 85 F and up, daily watering is often necessary.
