Growing Corn in Raised Beds — Your Complete Guide to Thriving Corn in Small-Space Gardens
Growing corn in raised beds gives you the chance to enjoy fresh, sweet corn even if you don’t have a traditional garden.

Corn often intimidates gardeners because it’s associated with big fields and spacious gardens. But raised beds make this crop easier, more manageable, and more rewarding than most people expect. With the right setup, your raised bed can become a productive mini corn patch.
