Hi, I've failed many seasons with garlic! However, after a lot of research, I have a solution to growing sub tropic garlic. The key is growing the right variety, that can handle our heat. Glen Large garlic is the winner! Plant in April. Harvest in October. I've had a bumper crop with this variety.

I agree Glen Large are the best variety for the subtropics. I'm just north of Brisbane and get amazing harvest if I plant and harvest at the right time. I bought Mine from Green Harvest. They include all the detail on how to grow. (https://greenharvest.com.au/)

It's too hot for them to grow in summer. Try growing garlic in Autumn and harvest around Oct-November

Dry them out in the sun/shade for two weeks. Then in a cool dry place in a tray, spread them out a bit.

What about growing elephant garlic in zine 9b? Is it the same as regular garlic?

It's best to plant hardneck garlic in zone 6B from the middle to late October or even early November. The key is you want it to be cold, consistently below 45°, at least every night time. The first freezing encounter triggers garlic to start producing roots and that would determine how healthy and large the plants grow. Keep in mind freezing above ground may not equal freezing below ground. If you plant it in too warm a time, like early October, it may stunt the growth. It may even rot the garlic if it's wet too long. You may be able to accelerate the process by keeping in the refrigerator for a few weeks I'm not even know people who have kept it in the freezer for a few days or longer hopefully triggering root growth. I haven't tried that so I don't know.
