I plant all my left over garlic from the store around Sept. October each year, and cover it with a row cover that lets in 80% or more sunlight and rain. Most of it grows fine that way(very slow during winter). I do cover it more when it gets to freezing, and take the cover off entirely when there is the occasional nice sun shiny day.
I usually plant them in the space where I grew my tomatoes. When they mature in May to 1st of June, I harvest them and plant bush beans in that space.
I also grow some garlic that I order for fall delivery. Garlic is pretty simple. Plant about 2” deep and 16 clove per sq. foot. My soil prep is a good dose of compost, and some bone meal (follow package directions)for the phosphorus.
I don’t grow a lot of garlic, since I have limited space, but it’s so easy, I have thought about growing it to sell.LOL
Thank you all for your garlic planting tips. A little more garlic in the diet is good for the lowering a bit of high BP. As for the breath—well, not so much.. (’
