This is something I should have posted a few weeks ago, but somehow it got lost in this craziness of life that I live. However, I wanted you to know how to do it as if you live in warmer climates you may still be able to plant the Garlic for next year.
There are 2 times in where you can plant garlic, Spring and Fall. However, I do find the Fall planting makes more sense as you can harvest the garlic, the following Summer (If you plant it in the Spring you have to wait until the second summer to harvested as garlic needs to get cold in the ground over winter to achieve its fantastic taste).
Planting Garlic is very simple, you should simply keep bulb from your late Summer harvest (or buy a bulb at your grocery store);
Separate the individual cloves (do not peel the cloves).
Find a small patch on where to plant it. Make holes in the ground about 1 to 2 inches deep, put the garlic clove in with the pointy part facing up, cover with earth, water and wait!
After about 2 weeks the garlic will sprout and you will see small garlic plants. Do not disturb them. As winter come the leaves will die out, and that is OK.
Come Spring they will come back again and the cycle will repeat itself. You will get nice Garlic Scapes in the late Spring and yummy Garlic in late Summer.
