Primary propagation of ohwia typically involves seed sowing and softwood cuttings. Success hinges on aspects like ample light, warm temperatures, and well-draining soil. It's imperative to consider ohwia 's susceptibility to root rot under excessive moisture. Generally, propagating ohwia presents moderate difficulty, with challenges arising from seed dormancy or cutting failures. For propagation, 1) sow seeds in spring after stratification, 2) take softwood cuttings early summer, 3) dip in rooting hormone, 4) plant in the appropriate medium, and 5) maintain consistent humidity and temperature.
