Cultivation methods
Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson is a desert wildflower that requires well-drained soil with a high percentage of sand. It prefers a sunny location but can tolerate partial shade. The plant is best propagated from seeds, which need to be planted in the soil during the fall season.
Watering Needs
Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson is drought-tolerant and requires minimal watering. It is important not to over-water the plant as it can cause root rot. The plant should be watered deeply once a week during the summer and once every two weeks during the winter. It is best to water the plant early in the day to prevent evaporation.

The Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson plant does not require much fertilization. However, it can benefit from a light application of a balanced fertilizer during the growing season. The fertilizer should be applied at half strength, every two weeks.
Pruning
The Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson plant is a low-maintenance plant and does not require much pruning. However, pruning can be done in the early spring or fall to remove the dead leaves and promote new growth. It is best to use a sharp, clean pair of pruning shears to avoid damaging the plant.
Propagation Methods for Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson
Propagation of Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson can be done through seeds, cuttings, and division.
Propagation through Seeds
The most common method of propagation is through seeds. The seeds can be collected from the plant after the seed pods have matured and turned brown. The seeds should be sown in the fall or winter in a well-draining soil mix, covered lightly with soil, and kept moist until germination. Germination can be slow and sporadic, taking several weeks to several months.
Propagation through Cuttings
Cuttings can also be taken in early summer when the plant is actively growing. Softwood stem cuttings about 4-6 inches long can be taken and rooted in a soilless mixture or a mixture of sand and peat moss. The cuttings should be kept moist and in a shaded area until roots form, which can take several weeks. Once roots have formed, the cuttings can be transplanted to individual pots or directly into the ground.
Propagation through Division
Cleomella plocasperma S. Wats. var. mojavensis (Payson) Crum ex Jepson can also be propagated through division in the early spring or fall. The plant can be dug up and carefully divided into smaller sections, each with its own roots and shoots. These sections can then be replanted in a well-draining soil mix and kept moist until established.
