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.

I have read plant around the shortest daylight hours day - 21st June - harvest around 21st Dec. I would think garlic would not require a lot of fertilising. You are trying to produce bulbs not a huge green top - so don't go overboard on the N. Start with a good fertile soil and maybe a top up after 3 mths - light on the N. A general veg fert would do at planting. Or compost or manures etc. Do some internet research about growing it.

Here's a tip ,to get your garlic sprouting prior to planting ( using cloves) separate the cloves ,place on a plate & put in the fridge ..the temperature drop & darkness shocks them into sprouting ...you will get both root& shoot growth so plant when roots about 5-10mm long ...

Also plant around end of June.

Garlic - Brisbane - Sub-tropical. Due to circumstances I planted garlic very late April. 60 cloves and a brilliant strike. Now - I have a sparse scattering of remaining plants. The majority got to about 200 mm (6 inches) high then just turned yellow and died. The remaining ones (probably 10) are as healthy as, look like I will get some great cloves and are spread across the garden in no discernible pattern. Any suggestions of hints?

If you look at the planting calendar at the top of the page - plant May June July. There is an old saying plant on the shortest day of the year and harvest the longest day. Hours of daylight that is. Yellow plants may mean lacking N. You may have over or under watered them.
