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.

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!

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

First time for me planting Garlic. I planted them last October. My question: Many of the green shoots I had have dried, now in Mid Feb. i noticed that new green shoot are coming up is this normal for garlic or did I do something wrong? my next question: I planted Tomato seeds on Feb. 1, 2024 Tycoons, Dixie Red, Celebrity and Juliets, they have 2 sets of true leafs and are about 4" tall, with temp. outside in the low 50's and daytime temp. Mid 60's is that a good time to harden them off? they are only 3 weeks old. Any Advise will help.

I live in central California, zone 9b. I plants softneck garlic last year and it did very well. I refrigerated it for 3-4 weeks and then planted in November. Doing the same this year.

I put in my zone and asked about garlic and this response was below the grid: "Not recommended for growing in USA - Zone 9a regions". Now I know that there is a lot of garlic grown in the USA, so don't know why it said that, in fact I used to live near Gilroy. Other web pages say to plant mid Oct. to Dec. Makes me wonder about the advice on this website. Am I reading it wrong?

I 've planted garlic in zone 9a several years & they do great. Softneck & some hard necks are fine to plant in fall for Spring harvest. I recently used Keen organics to buy garlic to plant. There are several good distributors on the net. Keen has great advice. Read it. You can grow garlic successfully.
