Choosing the Right Variety
When selecting a hibiscus variety, consider your climate and the intended use of the plant. Tropical hibiscus varieties (Hibiscus rosa-sinensis) are perfect for warm climates and make impressive houseplants.
Planting HibiscusSunlight: Hibiscus plants thrive in bright conditions. In northern areas, full sun is ideal, while in the intense heat of the south, filtered sunlight is better.
Soil: Ensure your hibiscus is planted in well-drained, fertile, moist, loamy soil. The rose of Sharon is tolerant of alkaline conditions
Water: Hibiscus plants are thirsty and should be kept moist. Water indoor tropical hibiscus regularly during the growing season
Temperature and Humidity: Hardy hibiscus can tolerate cooler temperatures, while tropical varieties need to be kept in humid conditions.
Hibiscus Care TipsFertilizer: Feed your hibiscus with a high potassium and high nitrogen fertilizer to encourage healthy blooms.
Pruning: Prune hardy hibiscus annually to promote air circulation and maintain plant health. Cut back after flowering, removing dead, damaged, and diseased branches
Propagation: Most hibiscus are propagated from cuttings. Select a healthy stem, remove excess leaves, and dip the cut end in rooting hormone before planting
Common Pests and ProblemsPests: Hibiscus are relatively pest-free, but red spider mites and aphids can be problematic, especially in low humidity.
Bud Drop: Extremes in temperature, insufficient light or humidity, and improper watering can cause bud drop in hibiscus plants.
