At this stage, thin out the seedlings and transplant them into individual pots when they have at least two sets of leaves.
Cuttings Propagation
Another reliable way to propagate Crotalaria variegata Welw. ex Baker var. humpatensis Torre is through cuttings. Take a cutting from a healthy Crotalaria variegata plant and remove all leaves except the topmost pair. Dip the cutting in rooting hormone powder and plant it in moist potting soil. Cover the pot with a plastic bag to help retain moisture and place it in a bright, warm spot. Remove the plastic bag after four to six weeks when the cuttings have developed enough roots.
Division Propagation
Crotalaria variegata Welw. ex Baker var. humpatensis Torre can also be propagated through division. Divide a mature plant into smaller sections, ensuring that each section has roots and stems. Plant each section in a well-draining soil mixture, and watering it regularly until it is established.
