Growing Hibiscus seeds is not complicated. Start the flower seeds indoors 6 - 8 weeks before the last frost is predicted. Most gardeners recommend nicking the seeds with a knife and soaking them overnight in warm water. Sow the flower seeds into small pots or starter trays using a well-draining, sterile potting mix. Lightly cover the seed and keep it moist, but not soggy.
The seeds can actually rot if the soil is too wet. Keeping the temperature consistently warm and the soil consistently moist will aid germination. After seedlings have developed and there are several sets of true leaves with the stems have begun to harden and become woody, the young Hibiscus plant can be moved to larger pots or to a protected place in the garden. These tender young plants should be introduced to the sun gradually over several days. At this point, water-soluble fertilizer can be used.
