Propagation of Hibiscus marlothianus K.Schum.
Hibiscus marlothianus K.Schum. can be propagated using several methods, including seed propagation, stem cutting propagation, and layering propagation.
Seed propagation
Propagation of Hibiscus marlothianus K.Schum. using seeds is relatively easy. Sow the seeds in a well-drained soil mixture that contains peat moss and perlite in equal parts. Seeds germinate at temperatures between 21°C and 27°C. Keep the soil moist, but avoid overwatering, as the seeds may rot.
Stem cutting propagation
Stem cutting is another effective propagation method for Hibiscus marlothianus K.Schum. Take cuttings of about 4 to 6 inches long from the stem. Use a rooting hormone to stimulate root growth and plant the cutting upright in a well-drained soil mixture. Keep the soil moist and place the cutting in a sheltered area with indirect sunlight. Once roots have developed, transplant the cutting to a larger pot or outside in a sunny area.
Layering propagation
Layering is also a viable propagation method for Hibiscus marlothianus K.Schum. Choose a healthy branch and remove a section of leaves at the base. Bury this section of the stem in the soil and leave the top section exposed. After several weeks, new roots and shoots will emerge from the buried section. Sever the newly rooted plant from the parent plant and replant in a larger pot or garden.
