In late summer they are ready to harvest when the tops begin to fall over; then just pull them from the soil and let them cure in a dry, airy location for 14 days. You can either braid the tops or cut them off, and store the onions in a dark, cool, dry location at a temperature below 55 degrees F.We cannot ship to Idaho or Washington
