The plant requires moist, well-draining soil that is rich in organic matter. Mimulus clarkii Kellogg ex Curran prefers a soil pH between 6.0-7.5, and can tolerate slightly acidic or slightly alkaline soil conditions. It does not tolerate salty or waterlogged soil, and may not survive in areas with poor drainage.
Cultivation methods
Mimulus clarkii Kellogg ex Curran is a low-growing perennial plant that thrives in full sun to partial shade. It prefers acidic soils that are moist but well-drained and can grow in a variety of soil types, including loam, sand, and clay. It is best to plant these plants in the spring after the last frost or in the fall before the first frost; the optimal temperature for growth is between 10-25 ° C.
Watering needs
Mimulus clarkii Kellogg ex Curran requires regular watering to keep the soil moist, but avoid overwatering because it can cause root rot. It is best to water the plant deeply once a week, rather than light, frequent watering, which can cause shallow roots. During the hot summer months, it may be necessary to increase the frequency of watering to keep the soil moist.
Fertilization
Mimulus clarkii Kellogg ex Curran benefits from regular fertilization during the growing season (spring to fall) with a balanced fertilizer. Use a water-soluble or slow-release fertilizer, and follow the package instructions for application rates. Avoid over-fertilizing as it can cause the plant to become leggy and lose its compact shape.
Pruning
Mimulus clarkii Kellogg ex Curran does not require much pruning, but it benefits from deadheading, which is the removal of spent flowers. This process encourages the plant to produce more flowers and prevents self-seeding. Trim back any yellow or dead leaves and stems, making a cut just above a healthy leaf. If the plant becomes too leggy or out of control, it can be cut back by up to half its height once every three years in early spring. This pruning encourages new growth and helps to rejuvenate the plant.
Propagation of Mimulus clarkii Kellogg ex Curran
The propagation of Mimulus clarkii Kellogg ex Curran can be done through seeds or cuttings.
Propagation by Seeds
The seeds of Mimulus clarkii can be collected in late summer or early fall and planted immediately in well-draining soil with a pH of 5.5 to 6.5. The seeds should be planted at a depth of 1/8 inch and kept moist for germination. Germination can take up to three weeks. Once the seedlings have reached a height of 3 to 4 inches, they can be transplanted into individual pots or into the ground.
Propagation by Cuttings
Cuttings of Mimulus clarkii can be taken in late spring or early summer when the plant is actively growing. A 4-inch cutting with several nodes is ideal. The lower leaves should be removed, and the cutting should be dipped in rooting hormone before being planted in well-draining soil. The cutting should be covered with a plastic bag or placed in a propagating box to retain moisture and encourage rooting. Roots can take around three weeks to develop, and once they have formed, the cutting can be transplanted into individual pots or into the ground.
