I have a corn patch that is about 20' X 30' and am currently harvesting sweet corn out of it right now. I figure in about another week I should be through harvesting the ears. The stalks should provide shade for about another 2 weeks before they dry up too much. So I'm thinking that while there is still shade I should start either a cover crop in between the rows or plant some type of vegetable and hope they are up and going before it gets too hot. In late July and August our annual summer drought could hit with temps of 100 or more, thus eliminating most vegetable crops. However I am not sure about cover crops that would survive that much heat. Any suggestions out there?
