Pruning
Coreopsis ruwenzoriensis S.Moore benefits from regular pruning. Prune back the plant after the flowering season to promote bushier growth and more flowers the following year. Deadhead the flowers regularly to encourage more blooms. Cut back any dead or damaged stems as needed to keep the plant looking tidy.
Propagation of Coreopsis ruwenzoriensis S.Moore
Coreopsis ruwenzoriensis S.Moore, commonly known as the Ruwenzori tickseed, is a delicate perennial plant that grows in the East African region. The plant is popular for its bright yellow flowers and its ability to attract bees and other pollinators. Propagation of Coreopsis ruwenzoriensis can be done through several methods.
Seed Propagation
Coreopsis ruwenzoriensis seeds are widely available and can be obtained from online stores or local nurseries. The best time to plant Coreopsis ruwenzoriensis seeds is in the spring.

Cutting Propagation
Propagation of Coreopsis ruwenzoriensis through cuttings is less common but can still be done. Take a 4-6 inch cutting from a healthy plant and remove the lower leaves. Dip the cutting in rooting hormone and plant it in a well-draining rooting medium. Water the cutting regularly and place it in a warm, bright location with indirect light. New roots should appear within two to four weeks, and the cutting can be transplanted into its pot or bed.
In conclusion, propagation of Coreopsis ruwenzoriensis can be done through seed, division, or cutting. With proper care, the plant can quickly establish itself and provide bright, yellow flowers year after year.
