I've only planted a few cloves in my time, this winter I planted three cloves over the last few weeks. It is a mild winter here in Queensland Australia. They get morning sun only, which is 24 degree celcuis max and usually 18 - 22 during the day. At night 0-14. I know garlic needs cool weather to grow.
The issue is the green shoots turned to a dying yellow and one plant died.
Is it the heat?
Too much or too little water?
Soil is rich enough, I dont know if ph levels affect garlic
