If your lantana plants are of berry-producing type, you can harvest the small berries once they’ve fully ripened. Remove the seeds and dry them out for a few days before storing them in a sealed container. Place the container inside the refrigerator. Soak the seeds in water for 24 hours before planting.
You can also opt to reproduce your lantana using its cuttings. Take about four inches of cuttings from new growth in spring. Leave only one or two leaves at the top and dispose of the other leaves. Cover the bottom of the cutting with rooting hormone and use soil for the surrounding areas to keep it upright when planting. Check your plant from time to time. Be patient, as rooting takes anywhere between two to four weeks.
