Hello. Our purple garlic is out of the ground. We tie them in bunches with dead stems intact . We take the roots off them. Question: the shed they are suspended in has a moist atmosphere due to the rain today. It has a dirt floor and no doors.Will this moisture cause them to rot or make them susceptible to pests or mites. We have about 800. Thankyou

My experience is with shallot bulbs. I just keep them loose in a pot tray/dish drying tray about 2-3 (??)

This is the way I see it. They recommend planting May to July for temperate - Perth. The reason is, this is when you will have the best results. Now if you go and plant it in Oct/Nov you will probably produce a smaller crop or no crop. You have to look at your local conditions also. It is like if a seed requires 20 degrees soil temp to germinate why plant it when it is 15 degrees.

I have garlic growing for the first time, they are lovely and green but i don't want to over or under water them. Can you give me some guide lines please. I have a dripper system with these, but wonder if that is giving the required amount or what is the optimum system and how much water, for garlic. I have no idea if they are hard or soft necked garlic! They were purchased from an organic grower but i didn't ask what style they are.

Stick your finger in the soil, down about 3-4 cm

Hi, I plant garlic every year, but it never goes to seed. Can you please advise on a fertilizing schedule please. I always plant before the first full moon in April. I have trouble getting it to keep all year through after its picked, dried and hung and wonder if this is because it didn't go to seed? Any how would be appreciated.

The issue you're experiencing is more likely due to the type of garlic you are growing than anything you're doing. Garlic is generally split into two categories: hard neck and soft neck. Your planting times are perfectly fine for an Australian temperate climate. The old sayings about planting on shortest day and harvesting on the longest actually comes from the northern hemisphere and aren't optimal for most Australian climates. I follow the advice of Penny Woodward, who has literally written the book on garlic in Australia. https://www.pennywoodward.com.au/garlic-plant-it-now/ If you read the link above, it explains that hard neck varieties of garlic don't last as long, whereas soft neck garlic varieties tend to keep better.

Thanks for the tip on shortest / longest day stuff. How do you distinguish between a soft and hard neck? I looked up a website and all they had was a white bulb and a light purple bulb.

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.
