Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Sea Hibiscus thrives in consistently moist soil, especially during its active growth phase. Water deeply when the top 2-3 cm of soil feels dry.
Reduce watering in cooler months, allowing the soil to dry out slightly more between waterings. Avoid waterlogging, as this can lead to root rot.
Prune Sea Hibiscus in late winter or early spring to shape the plant and encourage bushier growth. Remove any dead, damaged, or crossing branches. Light pruning can also be done after flowering to maintain its form.
Heavy pruning is best reserved for rejuvenating older plants.
Sea Hibiscus can be propagated from semi-hardwood cuttings taken in summer. Select healthy stems, cut them to about 10-15 cm, and remove lower leaves.
Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep moist and warm for best results.
Young Sea Hibiscus plants benefit from repotting every 1-2 years in spring. Choose a pot that is one size larger than the current one, using a well-draining potting mix.
Mature plants may only need repotting every 3-4 years, or when root-bound, to ensure continued healthy growth.
