Propagation of Helichrysum nimbicola Hilliard
Helichrysum nimbicola Hilliard is a small, mat-forming perennial plant with yellow flowers, native to South Africa. It grows well in well-drained soil and is tolerant of drought, making it an ideal plant for xeriscapes and rock gardens. In order to propagate Helichrysum nimbicola Hilliard, one can use the following methods:
Seeds
Propagation through seeds is relatively easy. Sow the seeds in a well-drained soil mix in the early spring, covering the seeds with a thin layer of soil. Water the soil well and keep it moist until the seedlings emerge. Once the seedlings are large enough to handle, transplant them into individual containers, or directly into the garden.

Cuttings
Helichrysum nimbicola Hilliard can also be propagated through cuttings, which is an easy and effective method. Take cuttings in the late spring or early summer from healthy, mature plants. Cuttings should be about four inches long and should be taken from the current season's growth. Remove the lower leaves from the cutting and dip the cut end into a rooting hormone. Plant the cutting into a well-drained soil mix and keep it moist until it has established roots.
Division
Propagation through division is another common method for Helichrysum nimbicola Hilliard. Divide the plant in the spring, when it begins to produce new growth. Carefully dig up the plant and separate the individual plants, being sure to keep as much of the roots intact as possible.

Additionally, applying insecticidal soap or neem oil can help control the spread of infestation.
Aphids
Aphids can colonize leaves and stems and lead to stunted growth and leaf distortion. To manage aphids, it is essential to remove affected parts of the plant and increase the population of beneficial insects such as ladybugs and lacewings. Additionally, applying insecticidal soap or neem oil can help control the spread of infestation.
