Cuttings
Crotalaria kassneri can also be propagated by taking cuttings from a mature plant. Take a 6-inch cutting from a stem that has several leaves attached. Remove the leaves from the bottom 3 inches of the stem and dip the cut end in rooting hormone. Plant the cutting in a pot filled with a mixture of compost and sand. Water the cutting and cover it with a plastic bag. Place the pot in bright, indirect light and keep the soil moist. The cutting should start to develop roots in about 4 to 6 weeks.
Division
An additional way to propagate Crotalaria kassneri is by dividing an established plant. In the early spring, dig up an established plant and use a sharp clean knife to divide it into several sections. Each section should include some roots and several stems. Plant each section in a pot filled with a mixture of compost and sand. Water the new plants and place the pot in a warm, bright, spot. Keep the soil moist and wait for the new plants to start growing.
Overall, Crotalaria kassneri Baker f. is an excellent plant for gardeners who are looking for a colorful and easy-to-grow plant. By using one of these three propagation methods, gardeners can quickly and easily increase their stock of this stunning flowering plant.
