Propagation of Malvastrum asperrimum var. stellatum
Malvastrum asperrimum var. stellatum is commonly known as prickly star mallow, and it is a member of the Malvaceae family. This plant is native to North America and is found in states such as Arizona, Texas, and New Mexico. It is a herbaceous perennial that can reach up to 3 feet in height and 2 feet in width.

The best time to propagate Malvastrum asperrimum var. stellatum is in the spring or fall by using seeds. The seeds should be planted in well-draining soil that has been amended with organic matter. To increase the germination rate, the seeds can be soaked in water for 24 hours before they are sowed on the soil surface. It is important to keep the soil moist until germination occurs, which can take up to 3 weeks.
Propagation by cuttings
Propagation of Malvastrum asperrimum var. stellatum can also be done through cuttings taken from mature plants. The cuttings should be taken from healthy and disease-free plants during the spring or early summer when new growth is just beginning to emerge. Cuttings should be 2 to 4 inches long and have at least one node. After cutting, the lower leaves should be removed, and the cutting should be placed in a well-draining potting mix. Keep the soil moist and in a warm and humid environment until roots develop.
Propagation by division
Malvastrum asperrimum var. stellatum can also be propagated by division. This is done by dividing the mature plant into several smaller sections, each with its own root system. This is best done during the early spring or fall, just before the growing season begins. The sections should be replanted immediately and kept moist until they are established.
Disease and Pest Management for Malvastrum asperrimum (Jacq.) A.Gray & Harv. var. stellatum (Thunb.) Harv.
