Propagation Methods for Lagascea mollis Cav.
Lagascea mollis Cav., commonly known as the velvet daisy bush or mata negra, is a beautiful evergreen shrub that could add an exquisite touch to your garden. Propagation is an affordable way to multiply your plants, and there are various methods to choose from.
Seed Propagation
The most common and straightforward method of propagating Lagascea mollis is through seeds. Collect seeds from mature plants, and sow them in seedbeds or containers filled with fertile soil. Water the seeds sufficiently and keep them consistently moist. It usually takes 2-4 weeks for the seeds to germinate, and once the seedlings grow 2-4 leaves, you can transplant them into individual pots filled with well-draining soil.
Cuttings Propagation
Cuttings propagation is a practical and efficient method of reproducing Lagascea mollis. The best time to take cuttings is during the active growth period, preferably in the spring or summer. Choose a healthy stem, make a clean cut, and remove the lower leaves. Dip the cutting in rooting hormone powder and insert it into moist, peat-rich soil. Place the cuttings in a shaded area and keep the soil consistently moist until the roots firmly establish. After the roots develop, transplant the cuttings into individual pots.
Division Propagation
Division is another approach to propagate Lagascea mollis. Divide the mature plant during the early spring before significant growth appears. Choose a healthy plant, dig the soil around the base, and carefully separate the roots into smaller sections. Plant each division in well-prepared soil and water thoroughly. Taking proper care of the new divisions would result in them growing independently and thriving.
