Overview
Tropical Hibiscus (Hibiscus rosa-sinensis) is native to Asia and is widely grown for its large, colorful flowers that last only one day but are produced in abundance throughout the warm season. It can be grown as a shrub or trained into a small tree form.
Care Guide
Light
Full sun (at least 6 hours) produces the most flowers. In very hot climates, light afternoon shade is beneficial.
Water
Keep the soil consistently moist but not soggy during the growing season. Reduce watering in winter.
Soil
Rich, well-draining soil. A good quality potting mix with added compost works well for containers.
Temperature
Prefers 60–90°F (15–32°C). Protect from temperatures below 50°F (10°C). Bring indoors before frost.
Fertilizer
Feed every 2 weeks during spring and summer with a high-potassium fertilizer to encourage flowering.
Pruning
Prune in early spring to shape the plant and encourage bushier growth. Flowers form on new wood.
Propagation
Hibiscus is easily propagated from cuttings taken in spring or early summer. Softwood cuttings root readily in moist soil or water.
Common Problems
- Yellow leaves & bud drop – Often caused by inconsistent watering or sudden temperature changes.
- Aphids, whiteflies, spider mites – Common pests; treat with insecticidal soap or neem oil.
- Few flowers – Usually not enough light or fertilizer.
Interesting Facts
- Each individual flower lasts only one day, but the plant produces them continuously.
- Hibiscus is the national flower of several countries including Malaysia and South Korea.
- Some varieties are used to make herbal teas.
