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.

Jesse, you should get one head (or bulb) of garlic from each plant. The bulb will contain a number of cloves. Some varieties produce more cloves than others.

how deep do i plant the garlic bulb - do i start it off first trying to get some roots developing or do i just plant a clove at whatever depth they require - thanks

I normally plant mine point end up about 25-30 mm below the surface. They can take a while to come up just like other bulbs such as daffodils.

I live just out of Dunedin where we get frosts and occasional snow storms, our winters could be classed as severe. Garlic is similar to shallots in that it was regarded years ago to plant both shallots and garlic on the shortest day (June 21st.) and harvest on the longest day (December 21st) How-ever I now plant my garlic at intervals from early May through to mid August with great results. I always plant my clove straight into the ground with the top about half an inch below the surface. Space your cloves about six inches apart, the best of luck with your future plantings. Tony

How and when do you grow garlic from seeds? I live in Wellington. Thank you.

I live in Wellington and have garlic growing currently from clove. I like growing things from seed but growing from clove is far more efficient if it’s for a kitchen garden. I opted for organic garlic from Commonsense. Plant directly in situ pointed end up into a 5-7cm deep hole, July is ok, takes about 6 months before ready to harvest.
