Propagation of Exochaenium grande (E.Mey.) Griseb. var. homostylum Hill

Exochaenium grande (E.Mey.) Griseb. var. homostylum Hill is a shrub that belongs to the Asteraceae family. Its propagation can be done by two methods: seeds and stem cuttings.

Propagation by seeds

Seeds should be collected after the plant has flowered. They should be cleaned and planted in a well-draining soil mixture. The seeds should be covered with a thin layer of soil, and the soil should be kept moist until germination, which usually takes up to 14 days. Once the seedlings reach 3-4 inches in height, they can be transplanted into individual pots until they reach the desired size for outdoor planting.

Propagation by stem cuttings

Stem cuttings are best taken in the early summer when the plant is actively growing. The cuttings should be taken from new growth, and they should be around 3-4 inches long. Remove the lower leaves and dip the cut end of the stem in rooting hormone before planting in well-draining soil. Place the pot in a warm and bright location, and keep the soil moist until the cuttings have rooted. Once rooted, the cuttings can be transplanted into individual pots until they reach the desired size for outdoor planting.
