Tropical hibiscus dazzles with huge, satiny flowers in red, pink, orange, yellow, and white—each lasting just one day, but produced in succession all summer. Indoors, it needs intense light, steady moisture, and regular pruning to stay bushy and blooming.
Full sun to very bright light. South window essential. Without 6+ hours direct sun, it won't bud. Summer: move outdoors to full sun (acclimate gradually).
Keep soil constantly moist in summer—water daily in heat. Mist leaves every 2 days. Winter: water weekly, let top dry slightly. Never bone-dry.
Summer: 65–75°F (18–24°C). Winter: 55–60°F (13–16°C) for rest. Avoid heat sources and cold drafts. Yellow leaves = stress.
Cut back hard to shape, remove dead/weak wood, shorten long shoots for compact form. Pinch tips for branching. More branches = more flowers.
Rich, humusy, well-drained mix. Feed weekly in summer with dilute balanced fertilizer. Stop in winter.
Spider mites, whiteflies, aphids. Inspect undersides. Spray with neem oil or insecticidal soap.
