I tried my hand growing corn this season. Knowing good and well it may be a failure. I wanted to see the characteristics of corn growing in my urban garden. I did get a couple of small ears to the table and rest looked like corn you get with your Chinese meal. But I did learn and will try again. I left a few ears on the dried up stalks and low and behold found what appeared to be the seeds that I originally started with. Pull the ear off and remove the kernels, place them on a plate and store in a cool dry place for a week or more. Then put them in an envelope and label the date and if you know the species. These will be used in my next corn growing trial.
After about a week, place in an envelope and label with as much information you can. Species, date stored, how many seeds etc…
