Three garlic plants were left in the ground to have the seeds, bulbils, fully dried and mature. The main bulb loses the outer sheath and the indivual cloves get much larger than when harvested with the sheath intact about the first week of July. I have also found that the bulbs without the sheath keep as long as the sheathed bulbs. I now intend to harvest when the bulbs start to lose their sheath due to having such large cloves. This means harvest will be about the end of August instead of the first week of July in my Zone 5.
