The easiest and most common way to propagate Dicoma superba is through seeds. The seeds can be collected from mature plants and should be sown in a well-draining soil mix. The soil should be kept moist but not waterlogged, and the seeds should be placed in a warm, bright location. Germination typically occurs within 3-4 weeks, and the seedlings can be transplanted once they have developed their first true leaves.
Cuttings
Dicoma superba can also be propagated through stem cuttings. The cuttings should be taken from mature plants during the growing season and placed in a rooting hormone. The cuttings should then be placed in a well-draining soil mix and kept in a warm, humid location. Once the cuttings have developed roots, they can be transplanted to their own pots or directly into the garden.
Division
Dicoma superba can also be propagated through division. This method involves separating the plant's root ball into smaller sections, each containing a portion of the plant's stem and root system. The sections should be planted in individual pots or directly into the garden, and should be kept consistently moist until they establish a strong root system.
