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.

We have been growing organic garlic on the Sunshine Coast for nearly 20 years Garlic that is falling over and not forming full bulbs can be caused by late planting, lack of nutrient, either from invasive tree roots, or not enough fertiliser. Lack of moisture can also cause this. The "round" is still either edible or will still grow a bulb the following season. For Garlic that is reshooting this can be caused by planting seed stock that has been "long cold stored" 1degree will cause this to happen. For growing garlic in the warmer climates, variety is important. Try and get a variety that is climatised to our warmer winter. Garlic likes it cool. A trick a customer told me was he gave it a frost by mulching it with a bag of ice regularly!
