I've tried to grow garlic for a couple of years now without much success. My last crop grown from store bought organic garlic, only had one large bulb. Is garlic a heavy feeder? What is the best way to prepare the bed for them?

Sometimes store bought garlic is treated with a chemical that deters it from sprouting. Can you get it from a local supplier? Organic?

It does not require a lot of nitrogen - just good friable soil with a little fertiliser.

Do some research of varieties - there wouldn't be that much difference.

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/)

If You grow garlic in 9b just requires refrigeration for 2-3 week min to trick it into thinking it winter. In summer you will have to use shade cloth and/or monitor water on really hot spells. I grow several hardneck & softneck last year. Might be a bit late to start the process now though.
