How to Prepare Day Lily Seeds

Many gardeners enjoy collecting seeds and growing new plants from them. We call the new plants that grow from collected seeds "hybrids." Because of the nature of seed collection, it is often a mystery and a surprise what these new hybrid plants will look like because they usually do not resemble the parent plant in color. You can collect, prepare and grow day lily seeds for a rewarding and inexpensive gardening activity.

Step 1

Watch the day lily plants as they grow and flower. After the plants are done flowering, a seedpod will replace the spent flower. After approximately two months, the seedpod will turn brown and open. Remove the black seeds from the seedpods and place them into the plastic bag.

Step 2

Fill the plastic bag approximately half-full with peat moss and add the 3 tsps. of water to moisten the peat moss around the seeds. Seal the bag and place it in the refrigerator for at least three weeks.

Step 3

Monitor the seeds in the bag during the refrigeration time. If you find any seeds that are sprouting, remove them from the bag and proceed immediately to Step Four.

Step 4

Remove the plastic bag from the refrigerator. Prepare the seed-starting tray by filling it with potting soil. Plant the seeds under approximately 1/4-inch of potting soil and spray the surface of the soil with the spray bottle. Keep the tray in a location with temperatures between 70 and 75 degrees.

Step 5

Keep the soil evenly moist during the germination time by spraying it daily. Watch for the seeds to sprout in two to six weeks. Move the seedlings to a sunny location or under a grow light after they sprout. Make sure they receive at least six hours of light each day.

Step 6

Fertilize the seedlings twice per week when the seedlings have two sets of leaves. Mix the fertilizer at half the recommended strength and apply with water.

Step 7

Transplant the seedlings outside when they are approximately 6 inches tall. Space the seedlings 4 to 6 inches apart.
