Propagate Hibiscus by Seeds and by Cuttings

Hibiscus are ideal plants to add to your garden. There are more than 200 varieties in the Hibiscus genus and some are easier to successfully propagate than others. Propagate hibiscus, whether it’s tropical hibiscus or hardy hibiscus, can be done in the home garden and both varieties of hibiscus are propagated in the same way. While a single bloom will only last for one day, hibiscus shrubs produce hundreds if not thousands of flowers each year. This floral display helps to explain their reputation as one of the best flowering shrubs.

Propagation from Hibiscus Seeds

While both tropical hibiscus and hardy hibiscus can be propagated from hibiscus seeds. Start hibiscus seeds indoors about 10 to 14 weeks before the last spring frost. Soak hibiscus seeds in room-temperature water for at least eight hours or overnight to boost the germination rate. Sow seeds 1/4 inch deep in moist soil that’s kept at 70-75°F. Seedlings should emerge in 14 to 21 days. When they do, place them in full sun.

Propagation from Hibiscus Cuttings

Propagating hibiscus using cuttings guarantees the new plant will be exactly the same as the parent. The cuttings should be taken from new growth or softwood. Using your clean, sharp pruning shears, cut the green stems, making sure they are at least 4 to 6 inches long. Remove everything but the top set of leaves. A 50/50 mix of potting soil and perlite works well. Make sure the rooting soil is thoroughly wet, then stick a finger into the rooting soil.

Place the new cuttings in a pot of well-draining soil that’s half potting soil and half perlite. Make sure the rooting soil stays damp until the hibiscus cuttings are rooted. Moisten the soil with water. Cover the cuttings with a clear plastic bag. The cuttings should be rooted in about eight weeks.
