  • 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.

  • 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 planted Australian Purple Garlic. Think it's the wrong variety. Grew ok..I think? But has been fairly static for a while. Confusing reading on garlic. Some say plant march and harvest in September.7 months. Most others say it's a 9 month crop. Any advice please. Tia John.

I’m in 7b. Will garlic thrive in pots and standing gardens?

It says to plant now. It all comes down to how fertile your soil is and whether you water them enough. Pots require more attention.

Can I plant garlic in KZN. It's a hot humid climate in the summer. Will get irrigation and water often.

There are several types of garlic, but the main two are hardneck and softneck. Hardneck is for colder climates and softneck is for warmer climates. Not sure about elephant garlic or any of the others but you can search the internet to find out what zones they grow best in.

I'd like to try my hand at growing garlic, but we can get some pretty hot spring days here in inland Southern California. I'm wondering if I might have better luck in our "screenhouse," which has full sun around the east, south, and west sides (regular window screen that doesn't block any sun). The roof is covered with shade cloth. I have successfully grown tomatoes, peppers, strawberries, and herbs in large containers in the screenhouse. I'm hoping there'd be enough shade to protect the garlic on those super hot, sun-intense days. Thoughts?
