Self-pollinating day lilies is the act of manually transferring the pollen from one day lily to the pistil of another. Many day lily gardeners treat this as a hobby and enjoy the beautiful and unique new day lilies they create from this process. To increase your chances of successful self-pollination, you may wish to grow your day lilies in a greenhouse or under a 30 percent shade cloth. Day lily pollination is best performed in temperatures of 75 to 85 degrees F and with little wind.
Select several day lilies to cross-pollinate. By pollinating several flowers you greatly increase your chances of success.
Gather the pollen from the ends of the stamen of one flower with your finger or a cotton swab. The best time to attempt self-pollination is in the morning, between 10 a.m. and noon.
Rub the pollen onto the pistil of another day lily. The pistil is the single, protruding part of the flower surrounded by the stamen.
Wait for the pollinated flowers to die off completely. If the pollination was successful there will be a small, green seed pod at the end of the flower's stem.
Allow the seed pods to dry, on the stem, and split. Remove the seed pods once they have split open and let them air-dry overnight.
Place the pods in a resealable plastic bag and place the bag in the refrigerator. Store the pods there for four to six weeks.
Plant the seed pods. Make holes 1/4 to 1/2 inch deep and 4 to 12 inches apart. Place the seed pods in the holes and cover them with soil. Water the seeds thoroughly. Plant when the soil is warm; late summer to early fall is ideal.
Water the seeds regularly to keep the soil moist. This encourages germination of the seeds.
Apply a liquid fertilizer to the soil regularly to encourage growth.
