Garlic is traditionally planted in cold weather and harvested in summer ("plant on the shortest day, harvest on the longest"). Plant the cloves (separated from the bulb), point upwards, deep enough to just cover with soil. A fairly tough and easy-growing plant but in better soil with regular watering you will get a better crop. On poorer soil, and forgetting to water them, you will still get some garlic, only not quite so much, maybe just a single large bulb.

Leave a garlic to go to seed, and you will probably get plenty of self-sown plants the following year.

To keep for later use, dig up and leave to dry out for a day or so after the green shoots die down. To use immediately, pull up a head when you need it, or cut and use the green shoots.

Culinary hints - cooking and eating Garlic

Cut the growing shoots or use the entire young garlic plants as 'garlic greens' in stir-fry.

We intend to plant garlic in an area 40x100 metres. Where can I source planting stock at a fair price? How good are the sales options in Mpumalanga for such a crop? Many thanks...

Noticed black mold while trimming up my harvest of Kettle River softneck garlic today. Been growing garlic 6 yrs now, trying different types. So disappointed, plants were big, bulbs came out huge, looked great. Cured in shade, then inside with a fan when temps got hot. What did I do wrong? Only thing I can think of is not restricting watering soon enough before harvest? Soil was not moist.

I planted garlic in May to keep critters out of my raised beds. It definitely helped with keeping the critters out. When should I expect to harvest? Would they still be good to eat, or do they need to overwinter? Thanks, Julie

An old saying plant shortest day of the year and harvest the longest day. (daylight hours that is)

So much garlic is grown in central California, zone 9, I'm so surprised it isn't recommended here! I'm going to give it a shot and see how it goes

I thought the same thing. I have grown Garlic successfully before in Fresno a few years ago in the fall. Some were small and some were average sized. I made sure they were planted with companion plants, etc. I bought bulbs from a reputable dealer, did all the things and ate the scrapes. I am going to try planting again this season. I'll start in the fall, specifically from late September to mid-October, for a harvest in late spring or early summer.

I live in zone 8A near Atlanta, GA. You can plant garlic here in the fall (October to December) before the ground freezes to harvest between May and July. Just in case someone was wondering - I've actually never planted garlic in the early spring as suggested here.

Thanks dude! I'm in the ATL area as well. I was hoping to plant some this fall/winter and was surprised when I saw the Feb/Mar dates.

Hi Al - Good companion plants for potatoes include horseradish, or comfrey planted between then slashed as mulch (its deep roots bring potassium up into its leaves - as a mulch the potassium is then released into soil for the potato) Also peas/beans used in same way. Haven't heard of garlic with potato. I do scatter chopped up garlic amongst lettuce seedlings as a temporary deterrent against slugs.
