Q.I Have Always Saved My Flower Seed With Great Results. This Year I Would Like To Save My Corn Seeds. Is There A Different Way?
Do I pick a well developed ear and just let it go on the stalk till fall then treat it same as flower seeds, or will they need something special like tomato seeds do?

To obtain the seeds, it is best to leave a few ears on the plant until they are completely dried out. Then you can pick them and store the whole ear, or separate the kernels and save them that way.
