Start Corn From a Leftover Cob
Most people finish eating corn and immediately throw the cob away. But under the right conditions, that leftover cob can actually sprout new plants. Place the cob into a shallow container with rice water or plain water so the bottom remains moist. Set it somewhere warm with plenty of sunlight and check it regularly to keep the water from drying out.
Over the following weeks, small green shoots will begin emerging between the kernels. Once several strong shoots have developed along the cob, carefully separate them and transplant each one into nutrient-rich soil outdoors or into large containers. Corn needs plenty of space and sunshine to thrive, but this simple trick lets you recycle something that would normally end up in the trash while giving your garden a head start.
