yea smiles made an oops putting it in the gardening with animals , the pics are of potato seed pods , you can grow potatoes from these pods but if they are a hybred you don't know what kind of potatoes you will get
The cans will rust , you could use old tires and just cut the sidewall out with a sawsall , you can also paint them to make them look nicer , another idea is get some plastic 55 gal drums , cut the ends off then cut in half , or just cut in half and drill holes around the sides at the bottoms...
I am looking into starting a small berry farm , I have 2 1/2 acres to play with , What raspberries have you done good with and what ones didnt do good ? I am in zone 4 to 5 LOL kinda boarder line right here
A guy I am friends with loaded me up 2 pickup loads of ground alfalfa that was moldy , I will be getting it on the garden this weekend , he has more in big square bales I will be putting in my compost pile along with a buch of sheep manure
