We reserve the biggest, most beautiful heads, In late October or early November, weather depending, Just before it’s time to plant, we separate those robust heads into cloves and plant them to become the subsequent season’s crop. Gardeners turned over the soil, dug furrows, planted cloves pointy end up, sprinkled compost from our garden waste windrow, and lightly covered the cloves. Garlic planting day is usually the last big, celebratory-feeling work party of the garden season. The last step is giving the planted garlic a thorough covering of leaves, which frees up the leaf bags for fun!
