How to care for your Hibiscus
Everything you need to keep your Hibiscus healthy: watering, light, humidity, feeding, repotting and pruning.
Hibiscus rosa-sinensis, or Chinese Rose, is a shrub native to tropical Asia that has become iconic in Mediterranean and tropical gardens worldwide. Its large funnel-shaped flowers, available in an endless palette of colors, open in the morning and fade by evening, replaced by new ones the next day. In summer, it can be placed on a sunny balcony or terrace, which it greatly appreciates. It is a vigorous plant that responds beautifully to regular fertilization and annual pruning.
Watering your Hibiscus
Every 3 days
Water thoroughly during the growing season to keep the substrate moist. Reduce in winter. Never leave the pot standing in a saucer of stagnant water.
How to know it needs water
- Topsoil dry 2–3 cm down
- Leaves beginning to droop
- Flower buds dropping prematurely
How much light a Hibiscus needs
Full sun
Full sun to bright light. At least 6 hours of direct sunlight daily for prolific flowering.
- Direct sun tolerated
- 6 to 10 h a day
- Orientations that suit it
- South, South-east, South-west, East, West
Humidity and misting
50–70 %
50–70% Mist regularly, especially indoors in heated rooms. Hibiscus appreciates ambient humidity but tolerates drier conditions than many tropicals.
Feeding and fertiliser
Every 7 days
Fertilize weekly during active growth (April–September). Reduce to once a month in autumn. Stop in winter.
- Recommended feed
- Liquid fertilizer high in potassium (NPK 10-10-20) to promote flowering. A hibiscus-specific formula is ideal. · 10-5-15
Repotting your Hibiscus
Every 12 months
Use rich, well-draining compost. Add compost and perlite. Move up one pot size at each repotting. Root-prune lightly if necessary.
- When
- Early spring, before new growth resumes
- Potting mix
- All-purpose potting mix
- Mix in
- perlite, coco fibre
The tell-tale signs
- Roots emerging from drainage holes
- Reduced flowering despite good fertilization
- Water running straight through without being absorbed
Pruning your Hibiscus
In late winter or early spring, before growth resumes. Cut back by a third to a half to maintain a compact, bushy habit. Flowers form on new-season wood, so pruning stimulates flowering.
Through the year
Watering is not set once and for all: it follows the light and the growth. Allow 5 days between waterings in the depth of winter, against 2 in the growing season.
