This is one problem. You are going to make some nice timbered beds for corn but corn should not be grown in the same place each year. I would grow corn the regular way...not in beds. You could rotate with beans.
Use the raised beds for other vegetables - my opinion
Thank you. Actually, that is my intent. But I have to persuade my husband to help me to put these in. I knew that I was going to run out of space, but my husband was reluctant to give me any more. They can easily be converted to other plants next year. And growing beans with them may just allow them to be used two years for corn — or all beans next year — or all squash — or ???
