I hadn’t thought of spinach; interesting idea. I could maybe do that early in the season. We get a lot of wind here, so when I’ve grown corn, I’ve had to space it fairly close together in a block so they hold each other up. I’ve always gone with the traditional 3 sisters combo of corn, squash, and beans. I admit, though, that I haven’t grown it for the past few years. Now you’ve gotten me thinking about how I could be more efficient with succession plantings. I appreciate your comment! Thank you!
