I want to plant bunching onion seed all the perimeter of my small garden plot as i have heard they will keep multiplying over time then you can harvest what you want and they will just grow back again. Has anyone done this and if so is there a particular kind that you would use. I remember when a small kid, my parents garden had these planted close to the fence and they called them "winter onions" i think these are the same as multiplier or bunching onions. help me out here if anyone knows.
