This year, I’ve decided to plant garlic in fall. To me, this is a bit of an experiment – because I’ve only ever planted garlic in January.
Garlic is a hardy crop that withstands cold very well and doesn’t suffer from many diseases. Most critters that threaten tulips, or other decorative bulbs, don’t touch garlic because the taste and aroma is so strong. If you can plan for it, you can even use garlic to plant in between roses or other plants that are easily plagued by pests. The repelling effect of garlic can then help protect more sensitive crops or plants.
White garlic is most common 
My method is pretty simple. I start with loose, tilled soil with a decent amount of composted manure/other organic material worked in. With a garden hoe I make rows at 20cm/7.8inch. I gently separate the cloves from the bulbs and remove most of the papery leaves. Then I plant the cloves at 10cm/3.9inch from one another in my rows. Close the rows with about 5cm of earth and wait until spring.
I chose to plant my garlic around the 15th of October, because for many spring bulbs this is the traditional planting-date. You want the weather to be cold enough so the garlic wont grow anything green above ground, but not so cold that it cannot grow its root-system because of ice. For many of you reading this, your ideal planting date will be different from mine. My advice; check gardening websites for the ideal date to plant spring bulbs in your specific area/zone. That would be the perfect time to plant your fall-garlic.
