The downside is that they are rather labor intensive and require a lot of stoop labor to plant and harvest.
I know. I've planted only watermellons this year though.
Gilroy is the Garlic Capital Of The World Still, we import 80%.
I would beg to differ on the harvesting part.
Planting them requires some effort but a decent sized bed can be put in in a few hours.
In the north, fall is the best time to plant and hardneck garlic is what you want for northern climates. I have found that the best for me is either Great Northern White or Romanian Red. Music has a good reputation but my bulbs didn’t get as big as the other two varieties.
And once you get a good crop, just save the biggest bulbs out for next year’s crop.
