I’ve tried growing garlic 2 years now, and never get actual cloves, they just grow until they die back, and when I pull them out of the ground all I have is a scallion-looking thing.
I live in Florida, zone 9, with a sandy soil. I’ve added compost, peat moss, vermiculite to amend the soil. I’ve fertilized with both fish emulsion and commercial granular all-purpose vegetable fertilizer.
The first year I just used a garlic clove from the grocery store and got the above result, they were in the ground for almost a year. The second year I figured it was the garlic I planted and ordered seed garlic from a catalog, selecting a variety that should do better in a hot climate. Same result. This batch was planted in December, grew beautifully all winter and spring, died back substantially in the past month, and when I started to pull them up, nothing.
