Why Your Potted Hibiscus Isn't Blooming: Light and Temperature Needs

A hibiscus in a 5-gallon pot, cut back 3 years ago, with healthy green growth but no flowers, kept indoors in partial sun, is almost certainly a tropical hibiscus.

What It Needs

• Warm outdoor temperatures to break dormancy.
• Full sun (6+ hours direct).
• Consistent watering and feeding during the growing season.

Indoor Limitations

Indoors, light intensity is too low to trigger blooming. The plant survives but remains vegetative.

Solution

Move it outdoors after the last frost. Place in full sun, water regularly, and fertilize with a balanced formula. Blooms should appear within weeks.
