Hard neck garlic

[On the Moors]

I planted some in tubs early October last year. Apparently they will be ready for harvesting when the leaves turn yellow. They look quite green and healthy at the moment so when can I expect the leaves to turn?

Howdy. I grow the soft neck garlic so it may be different for hard neck garlic, but I plant it in Oct. and about 1/2 the leaves turn yellow the following late May early June here.

Garlic is a little different from onions in that all the leaves don't yellow only about half and the other half stays green whereas onions completely yellow and flop over at bulb maturity.
