Hibiscus

How to care for hibiscus

• Light: Requires full sun, at least 6-8 hours of direct sunlight daily, to produce the most abundant flowers. Less sun will result in fewer blooms.
• Water: Water thoroughly and regularly, keeping the soil consistently moist, especially during hot, dry periods. Do not allow the soil to dry out completely between waterings.
• Soil: Prefers rich, well-draining soil with a slightly acidic pH. Amend with compost or other organic matter to improve fertility and drainage.
• Temperature: Tropical hibiscus (H. rosa-sinensis) thrives in warm temperatures, typically above 60°F (15°C), and is very sensitive to frost. Hardy hibiscus (H. moscheutos) is more cold-tolerant.
• Humidity: Prefers high humidity, especially tropical varieties. Indoor plants benefit from misting or a pebble tray to increase humidity.
• Fertilizer: Feed regularly every 2-4 weeks during the growing season with a high-potassium fertilizer to encourage flowering. Reduce feeding in fall and winter.
• Propagation: Easily propagated from softwood stem cuttings taken in spring or summer. Root cuttings in a moist, sterile potting mix with rooting hormone.

Is hibiscus toxic to pets?

Not pet-safe. Hibiscus (Hibiscus syriacus, H. rosa-sinensis) is considered non-toxic to cats, dogs, and horses by ASPCA. Some sources suggest mild gastrointestinal upset with large ingestion. See our guide to toxic plants for cats and dogs.

Common problems

• Yellowing leaves/Bud drop: Often caused by stress from inconsistent watering (too much or too little), nutrient deficiencies, or sudden temperature changes. Ensure consistent care.
• Aphids/Spider mites/Whiteflies: Spray affected plants with insecticidal soap or neem oil. For severe infestations, introduce beneficial insects or use targeted pesticides.
