Some one recently spoke of practicing things NOW and I thought of gardening, I think so many people feel like you just put some seeds in the ground and then you have all the food you can eat.
Back ground; I grew up in the country in the southeast. At the age of 12 helped with an 1/2 acre garden and had 2 acres of okra that was mine that I sold wholesale to A&P grocery store. As a adult I had many gardens in different areas of the S.E.
This year I decided to plant heritage veggies, I have never used GMO however I usually use newer hybrids that are nematode resistance and breed for back yard gardens.There is nothing " wrong" with this except next year you may not have access to seeds. You can not keep the seeds of hybrids and expect a decent result. That is the whole reason for using heritage breeds, they reseed "true".
Well, I have had poor results with most of the seeds. Some were complete failures (carrots and radishes). I have enough Squash, Corn, Peas, Beans and melons to at lest get more seeds and maybe eat a few items. I also experimented with growing wheat, it was pretty decent. Just remember with wheat you need to plant 1 lbs, to get 9 or 10 lbs. harvest.
So my take away is even if you "think" you know how to have a garden I would suggest trying some heritage breeds this year and get experience growing the old breeds and saving seeds.
