Here’s a growing guide for Hibiscus Rosa Sinensis in Hawaii at an elevation of 100 feet:


  • Elevation: Hibiscus Rosea Sinensis thrives at lower elevations, like the 100 feet mentioned.
  • Temperature: It prefers temperatures between 60°F (15°C) and 90°F (32°C). Avoid planting in areas with strong winds or salt spray.


  • pH: 6.0 to 7.5. Hibiscus prefers slightly acidic to neutral soil.
  • Type: Well-draining soil enriched with organic matter. Consider adding compost or aged manure.


  • Frequency: Water regularly to keep the soil consistently moist but not waterlogged. Hibiscus doesn’t like to dry out completely.
  • Considerations: Use mulch to retain soil moisture and reduce water evaporation.


  • N-P-K: Use a balanced fertilizer like a 10-10-10, or one with a slightly higher middle number for encouraging blooms, such as 10-20-10.
  • Frequency: Apply once every month during the growing season.


  • Intensity: Full sun (at least 6 hours daily) to partial shade. The plant will produce more blooms in full sun.


  • Timing: Late winter or early spring before new growth starts.
  • Purpose: To maintain shape, promote business, and remove dead or diseased branches.

Pests and Diseases:

  • Common pests: Aphids, spider mites, and whiteflies.
  • Common diseases: Rust, fungal leaf spots, and bacterial blight.
  • Management: Regularly inspect plants, keep the foliage dry when watering, and consider organic or chemical treatments if infestations become severe.


  • Method: Stem cuttings. Take cuttings from young, healthy, and non-flowering shoots. Root them in a well-draining potting mix.


  • Blooming: Hibiscus rosa-sinensis can bloom year-round in Hawaii’s climate, but it’s particularly prolific during warmer months.
  • Cultivars: There are many varieties with different flower colors and forms. Choose based on your aesthetic preference.


Hibiscus rosa-sinensis is relatively easy to care for in Hawaii’s climate. Provide it with the right conditions, and it’ll reward you with a profusion of beautiful flowers.
