Here are some harvest tips. Don't let the plants get overly mature. Waiting longer can result in the splitting of bulb wrappers. And once plucked from the ground, be sure to keep the bulbs out of strong sunshine as they can sun scald very easily. This turns the clove flesh a rather unattractive green color.
Most bulbs have several very large cloves.
We have had some bulbs weighing in at close to a pound. But quarter pounders taste just fine too. Occasionally you will find one that appears to be just a single clove, rather like a golf ball in size. Elephants, like all garlic must be cured for several weeks in a well ventilated place. Packing moist, freshly harvested bulbs too tightly invites an outbreak of nasty fungus.
