Emma, try Tasmanian gourmet garlic. They sell to people up here like us. If you're in Danbullah you are probably subtropical or temperate (like us at Lake Eacham). They have some great information on their website as well. Start of May is the time to plant, depending on how wet it is.

Thank you ROD from Lake Eacham for your information, cheers.

The temperature in the freestate goes down to minus 10 ⁰c and 39 ⁰c in summer. Can i plant garlic to grow during the winter here?

I generally have garlic in my compost -- little bits that have maybe rotted a bit, and I can't even imagine how they grow -- but anyhow ---- I dig kitchen scraps directly into the garden over winter. Winter here gets down to about -10c for short periods of time (several nights in a row, for half a dozen hours at a time) -- generally winter temps are closer to -3c at night. Anyhow, come spring the areas where I have dug in kitchen scraps directly into the garden are usually sprouting : potatoes and garlic (among other things). So despite that I am actually planting garlic in winter, it will not grow until spring. I also grow garlic via the two year method (collecting seeds called bulbils - planting them immediately upon collection (so fall) )-- they grow in spring -- and then next year, they grow the garlic. Depending on the TYPE of garlic you are growing you can get 60 or more bulbils from one flower -- so this is economical if you have the SPACE. Again, the garlic is overwintered directly in the garden. In my area/zone, you have to yank out garlic if you don't want it -- because it just seems to grow and grow (same thing with fuchsia and potatoes).

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.
