I have grown elephant garlic which is related to the leek or years and have had great success. Last fall I planted Spanish garlic for the first time. I started with large purple garlic bulbs that had large cloves. They grew well all winter and I harvested them this morning. Everyone of them had a single bulb without cloves. I am a little disappointed but I think I need to cure the bulbs and plant them again in the coming fall. Any advise on how to proceed will be appreciated.
