Daylilies are perennial plants and they are called daylilies because many of them bloom during the day and either close or lose their petals at night. They are low-maintenance flowers that do well in many types of soil with varying amounts of water. Daylilies need a winter season to refresh themselves, but if their roots are not established in the ground by October, it is best to store them through the winter.
- Moderately Easy
Things You’ll Need
- Gelatin capsules
- Labeled storage tub
- Silica gel bag
- Permanent marker
- Freeze daylily pollen for up to a year before using it. Scrape the pollen off the stamens in the daylily and place it in gelatin capsules. Seal the capsules and place them in a labeled storage tub with a silica gel bag in the freezer. Write the date and any identifying colors or marks from the flower on the label with a permanent marker.
- Refrigerate seeds in labeled self-seal plastic bags. After seed pods ripen and crack on the daylily, label the self-seal bags with the date and identifying colors or marks from the parent plant. Drop all of the seeds from that plant into the bag and seal it. Place the bag in the refrigerator until you are ready to plant the seeds from the seed pods.
- Find a space that stays between 35 and 45 degrees Fahrenheit during the winter. If you have a storage shed in your yard or a cold storage area in your home, those work best. Fill a bucket halfway with moist peat and submerge the bottom of the daylily bulbs in the peat and leave them there until you plant them after the last frost in the spring.
- Let potted daylilies continue to grow in a greenhouse during the winter, if you do not have a chance to plant them in the early fall. You can use either a cool or warm greenhouse to store potted daylilies. Make sure you continue to water them throughout the season, but do not let them frost. Do not use a cold greenhouse which gets down to 28 degrees at night.
Tips & Warnings
Daylilies that have established themselves in the ground do well there during the winter and do not need to be transplanted or moved into a greenhouse. They start growth in the spring again on their own.
