Remove flower stalks once they have finished blooming as it encourages the plant to produce more flowers. You can also thin the plant by dividing the plant every three to four years. Remove old or decaying clumps and replant with healthy clumps for better growth.
Propagation of Hemerocallis lilioasphodelus L
Hemerocallis lilioasphodelus L, commonly known as lemon daylily, is a perennial plant that is native to Asia and Europe. It is a popular garden plant due to its attractive yellow flowers and low-maintenance nature. Propagation of this plant can be done through several methods which include:
Division
Division is the most common and easiest way of propagating Hemerocallis lilioasphodelus L. It is best done in the spring or fall when the plant is either starting to grow or entering dormancy. The process involves carefully digging up the plant and separating the rhizomes (underground stems) into small sections, each with at least one shoot. These sections can then be replanted in a new location or in separate containers.
Seeds
Propagation can also be done through seeds. The seeds should be harvested when the seed pods turn brown and dry. The seeds should be sown immediately or stored in a cool and dry place until the right time for planting. To increase the germination percentage, it is advisable to soak the seeds in water for 24 hours before sowing them. The seeds should be sown in a well-drained medium and kept moist. Germination should occur within 2 to 3 weeks.
Cuttings
Cuttings can be taken from Hemerocallis lilioasphodelus L in the late spring or summer when the plant is actively growing. The cutting should be taken from the stem just above the node and should be 4 to 6 inches in length. The leaves on the lower half of the cutting should be removed, and the cutting should be planted in a well-drained medium. The cutting should be kept moist until roots form, which should take around a month.
In conclusion, Hemerocallis lilioasphodelus L can be propagated through division, seeds, and cuttings. These methods are simple and easy to execute, making it possible to propagate the plant at home without any special equipment or training.
