Propagation of Croton californicus Muell.-Arg. var. mohavensis Ferguson
Croton californicus Muell.-Arg. var. mohavensis Ferguson is a California native plant that is commonly propagated through seeds and stem cuttings.
Propagation by Seeds
The best time to collect seeds of Croton californicus Muell.-Arg. var. mohavensis Ferguson is in late summer to early fall. The seeds should be collected from healthy and mature plants. After collecting the seeds, they should be cleaned and stored in a cool and dry place until the planting time.
The seeds of Croton californicus Muell.-Arg. var. mohavensis Ferguson have hard seed coats that can inhibit germination. To overcome this, it is recommended to scarify the seeds before planting. Scarification can be done by rubbing the seeds with sandpaper or by soaking them in hot water overnight.
The seeds of Croton californicus Muell.-Arg. var. mohavensis Ferguson should be planted in a well-draining potting mix and kept moist until germination. The seeds usually germinate in 2-4 weeks.
Propagation by Stem Cuttings
Croton californicus Muell.-Arg. var. mohavensis Ferguson can also be propagated by stem cuttings. This method of propagation is usually done in the spring or summer months when the plant is actively growing.
The stem cuttings should be taken from healthy and mature plants, and they should be about 3-4 inches long. The lower leaves of the stem cuttings should be removed, and the cuttings should be dipped in a rooting hormone powder before planting.
The stem cuttings of Croton californicus Muell.-Arg. var. mohavensis Ferguson should be planted in a well-draining potting mix and kept moist until roots have formed. This usually takes about 4-6 weeks. Once the roots have formed, the new plants can be transferred to larger pots or planted directly in the garden.
