After harvesting your daylily bulbs, it's important to store them correctly to prevent them from mold or rot, and to keep them from rooting and sending out new growth before they are planted in the spring. Fortunately, it's easy to do things right.
Remove excess dirt from the bulbs by shaking them gently. Dislodge any stubborn pieces with your hands.
Place the bulbs in mesh bag. The bigger the bag, the more bulbs you can store in it, but you still want to have air circulation so don't overfill. Leave plenty of room.
Store the daylily bulbs for winter in a cool, dry location. Humidity is the enemy, so be wary of dryer vents and wet basements. The ideal temperature is above freezing but no warmer than 50 degrees Fahrenheit.
Hang the bags in the storage location. Check them once every few days for signs of dampness or mold. If any bulbs become moldy, remove them and discard. Move the other bulbs to a clean mesh bag to prevent the mold from spreading.
