I would love to trial grains of all kinds.
I am NOT a master gardener. I finally got green peas to grow for me last year, a trial from the other forum! I have enough to actually grow a crop this year.
I did however, grow up in the Mississippi delta and we grew winter wheat, soybeans and cotton, the neighbor raised rice. So, my weather used to work for winter grains, as well as summer crops, who knows with the way weather is now? It is more my soil or lack of that is an issue...
I grow garlic overwinter. I tried potatoes, they rotted. But, with tunnels I could year round garden, except for a week or two... when it gets severe.
I honestly have never grown any grains, I did grow corn once. I got the grains to learn how to grow them, I thought I would try small quantities to learn to grow them. Most years, corn dies for me, before it gets 12" tall.
Mostly, I have grown tomatoes, peppers, herbs, potatoes, sweet potatoes, garlic, tobacco, cabbage, and lettuce.
Pawpaws are understory trees, they don't like sun. Not alot of anything grows underneath them. There is a wild rose bush growing under one, that gets the setting suns rays.
