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.

Can I plant garlic as late as the end of November or is that too late to allow it to overwinter?

Check the planting guide here for your climate zone. Look up some gardening internet seed companies for bulbs.

I noticed it says garlic is not recommended for USA zone 9b. I am in 9b central California. I plant garlic every year mid-December and harvest it mid-June. With the winter rains I don’t worry about watering it until April or May. I have not had any trouble with slugs/snails eating it (like they do with everything else in my winter garden!) Super easy to grow, everyone in zone 9b should try it!

What is the name and variety of the garlic you are growing in zone 9B? I'm hoping to grow some garlic in zone 9B as well.

Planting Garlic between four and 6 inches apart so how deep to plant this garlic in that type of soil Is fluffy soil in organic compost mix with rich top soil how deep to plant garlic

I planted my garlic cloves in July. In Southern California I know that's probably not the right time to plant them, but it doesn't get cold here. They've already started shooting out green shoots, and I'm not sure if I should leave it just keep growing or if I should cut those shoots off to stop it from growing for now. I'm assuming I should not harvest it until like next spring. Can you offer advice on what I should do now to keep the garlic growing so that I can harvest it next spring. I'd appreciate anybody's help. Thank you

Going to plant my first fall garden in my raised beds. I had a great year. Can you recommend the best place to buy seeds and bulbs that are local to East Coast Canada? I also have downloaded your app so I can take your advice to my garden with me. I love the layout of your website it's so easy to use.

I have already planted my Garlic and I was looking at bags of Garlic Cloves in my local shop. Reading through the instructions it said "Do not mulch Garlic". Wondering what your thoughts are. I mulched mine straight after I planted it. We have had a lot of rain. I am on the Central Coast NSW.
