(Best months for growing Garlic in USA - Zone 5a regions)

  • P = Plant cloves

September: Garlic can overwinter. Cover with a good layer of mulch . In areas where frost persists into March/ April, expect to harvest your garlic in June/July.

October: Garlic can overwinter. Cover with a good layer of mulch . In areas where frost persists into March/ April, expect to harvest your garlic in June/July.

  • Easy to grow. Plant cloves. Best planted at soil temperatures between 50°F and 95°F. (Show °C/cm)
  • Space plants: 4 - 5 inches apart
  • Harvest in 17-25 weeks.
  • Compatible with (can grow beside): Beets, Carrots, Cucumbers, Dill, Tomatoes, Parsnips
  • Avoid growing close to: Asparagus, Beans, Brassicas, Peas, Potatoes
  • Mature cured garlic
  • Almost ready to harvest
  • Garlic cloves
  • Mature cured garlic
  • Young garlic shoots

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 was not able to find anyone selling day neutral varieties such as Southern Glen; sounds as if day lenght makes a huge difference in warmer subtropical climates; does anyone have advice as to which variety will form the best bulbs in the Lowveld's warm winters

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 have successfully grown garlic for several years now with huge success however this year most of my crop has secondary sprouting. I seems that the time their ready for picking in around 4 > 6 weeks most will be lost due to all cloves within the bulb sprouting. PLEASE any thoughts as to what's going on.

Hi Kelvan, I haven't had the sprouting problem but after 30 years of growing garlic I have just harvested the worst crop I have ever had, but having talked to fellow growers, they also have experienced lesser quality garlic and some premature sprouting as well. It is worth noting that we have experienced colder temperatures this springtime and below 15 degrees celsius soil temperature whilst bulbing will induce early sprouting. On numerous occasions I have placed garlic in the refrigerator in February to bring on earlier sprouting. I usually plant over 500 cloves each year and some years over 5000 and give the garlic away to people who can't afford the ridiculous retail prices. Of course also to replace the weak quality, low pungency Chinese garlic. I am a great believer in planetry positioning within the universe, it has a large effect on weather and all forms of life and will certainly effect all growth and evolutionary factors. Perhaps next year will be a better one or we might have to plant later as it appears the planet is cooling.

Is it recommended to separate the cloves from the bulbs right before plating or to do it a day or two before?

Just remember to only select the largest cloves and eat all the small ones for yourself. The cloves determine the size of the harvested garlic. If you select only the largest cloves then as the garlic grows and the protective outer cloves develop around the centrally planted seed, they will develop to a size that matches the original clove you plant. Small clove = small yield. Large cloves = much larger yield. Being selective about saving only the very best and largest seeds for many different types of plants is going to serve you well. I think my kids are always slightly disappointed that we always have to 'eat the mistakes' while the very best of what we grow is saved as seed for an even better harvest next year. I guess it is the same principle as animal husbandry.

Either way.

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’m in 9b, central California and I have grown garlic for a few years. I “plant on the shortest day of the year, harvest on the longest day.” It has worked. Originally I just started with some organic grocery store garlic clusters, but now I save them from one year for the next.

I would like to choose 2 types of softneck garlic. Any suggestions on which two to choose? I also heard about elephant garlic. If it will grow in 5B... I may just grow that type. ?????? Undecided!
