(Best months for growing Garlic in Australia - sub-tropical regions)

  • P = Plant cloves
  • Easy to grow. Plant cloves. Best planted at soil temperatures between 10°C and 35°C. (Show °F/in)
  • Space plants: 10 - 12 cm 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 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.

My March/April garlic completely failed. Can I plant some more now (September).

Plant around mid -late June.

Can a small complete bulb of garlic be replanted to grow larger in the next growing season.

Certainly, BUT GENERALLY you break your bulb apart into it's constituent CLOVES and plant each clove separately. That is, each clove becomes a garlic plant.

Yes

I store my garlic in an onion bag and hang it up inside the shed.

Heres an answer for garlic, I grow about 300 plants a year and get good results with about 90% of the cloves coming in at 5cm in diameter plus. Season. Garlic takes up to 9 months to mature. Plant in autumn, late March to May, harvest November to December. Clove selection. Plant only the largest cloves, at least the size of your top thumb joint, I have big hands so I plant cloves 2- 2.5 cm across. Its easy to eat the biggest and the best, its better to plant the biggest and the best. Spacing. I plant 15 - 18 cloves per square metre, 25cm apart in rows 25 cm apart. With 30 cm + paths between 4 rows. It's easy to crowd them, and the yield in terms of weight may be much the same, but bigger garlic are a lot more fun and much easier to use in the kitchen. Sunlight. Whilst garlic can tolerate low sun during the winter months it needs 8 hours direct sunlight during the early and late growth stages. So lots of clear sky when it's maturing, September onwards. If your nutrition is right, (and soil acidity is right) then water could be the problem. While not much water is needed in winter, the ground should be kept moist through the season, especially in spring. A shallow watering is best the roots don't go down more than 30 cm max. Once to twice week during the maturing season. We cant control the weather, but avoid flooding (and applications of nutirients) during the final few weeks to lessen the chance of fungus attacks and sprouting. Garlic likes a moderate amount of lime (dolomite), you can rely on the recommended amount at least two weeks before planting and once every three years. Maturity. Look for tops fading in colour, a weakening of the stem near the base and a flattening of the top of the bulb when (gently) exposed Thats a lot and there's a lot more. It's a labour of love and a lifetime. And I'm sure others will have other suggestions, this is just a framework of what has worked for me. Planting at the moment actually. Regarding shallots most of the above also applies but Im not much of an authority. Shorter season length, but most of the above applies. I plant under the same conditions as garlic but only a few dozen and get good results.
