Whether you’re just starting your indoor plant journey or want a new addition to your tropical landscape, this guide is designed to help.
What Is Ixora (West Indian Jasmine)?
Ixora is a genus of evergreen shrubs and small trees native to tropical Asia, especially India and Sri Lanka. As a flowering houseplant, it has gained popularity across warmer parts of the world for its year-round blooming capability in ideal conditions. Its flowers grow in large clusters and come in striking colors like red, pink, yellow, white, and orange.
Often used as a hedge, ornamental border, or a container houseplant, Ixora can grow up to 12 feet outdoors. But indoors, dwarf varieties like Ixora coccinea usually stay around 2–3 feet, making them a manageable option for indoor plant lovers.

Best Growing Conditions for Ixora
1. Sunlight Requirements
Ixora needs at least 6–8 hours of bright, direct sunlight daily. Outdoors, place them where they can soak up full sun. Indoors, keep them near a south or west-facing window or use a grow light if natural light is insufficient.
2. Ideal Soil for Ixora
Ixora is an acid-loving plant. The optimal soil pH is between 5.5 and 6.5.
For Outdoor Planting:
- Use loamy or sandy soil
- Amend with peat moss or compost to maintain acidity
- Ensure good drainage
For Indoor Houseplant Growth:
- Mix equal parts of perlite, peat moss, and all-purpose potting soil
- Avoid using regular potting soil alone, as it can compact over time and hinder drainage
3. Temperature and Humidity
Ixora thrives in warm temperatures. Ideal temperatures range from 60°F to 85°F (15°C to 29°C).
- Not frost-tolerant – if you live in USDA Zone 9 or lower, grow Ixora as a container plant and move it indoors in winter
- Loves humidity – mimic tropical environments by misting the leaves or placing a humidifier nearby indoors
4. Watering Schedule
Ixora prefers evenly moist soil.
- Outdoor Plants: Water deeply once per week
- Indoor Plants: Water every 2–3 days during summer, and reduce frequency in winter
- Container Plants: Drainage holes are essential to avoid root rot
5. Fertilizing Your Ixora
Use a slow-release fertilizer for acid-loving plants, such as those formulated for azaleas or camellias.
- Frequency: Every 6–8 weeks during the growing season (spring to early fall)
- Application: Sprinkle fertilizer around the plant’s base—not on the trunk—and water it in
- Indoor Plants: Foliar feeding once a month boosts bloom production
How to Plant Ixora
Indoor vs. Outdoor Growing: What’s the Difference?
Outdoor Ixora enjoys natural sunlight and thrives in warm, humid climates. It requires regular watering but benefits from seasonal rainfall.
Indoor Ixora is more challenging to grow due to limited light and humidity. Placing it near a bright window, using a humidifier, and misting regularly can help mimic its natural environment.
To plant Ixora, use well-draining, acidic soil enriched with compost or peat moss. Whether you’re growing it in the ground or a pot, proper placement and watering are key. Learn the full step-by-step process in our dedicated guide on How to Plant Ixora.
How to Propagate Ixora
1. Propagation by Cuttings (Most Reliable)
- Take 5-inch stem cuttings from new growth during spring.
- Remove lower leaves, and dip the cut end in rooting hormone.
- Plant in a soilless mix of peat and perlite.
- Cover with a plastic dome or bag to retain humidity.
- Place in filtered light and keep the soil moist.
- Roots should develop in 4–6 weeks.
2. Propagation by Seeds (Slower and Less Reliable)
- Soak seeds overnight in water.
- Sow in acidic seed-starting mix.
- Keep at 65–70°F in filtered light
- Germination can take up to 12 weeks.
Note: Seeds can be hard to source and often have a low germination rate. Cuttings are more effective.
Pruning
Pruning is essential for maintaining a healthy and attractive Ixora plant, whether it’s used as an indoor houseplant or outdoor hedge. Done properly, it encourages bushier growth, improved airflow, and abundant flowers.
Why You Should Prune Ixora
- Helps maintain the plant’s size and tidy shape
- Encourages more vibrant blooms and dense growth
- Removes dead, damaged, or diseased branches
- Enhances air circulation and sun exposure within the plant
When to Prune Ixora
The best time to prune Ixora is in spring or right after a blooming cycle. This supports new growth and sets the stage for future flowers. Light pruning or deadheading can be done throughout the season to maintain its shape and promote ongoing blooming. Avoid pruning too early (frost risk) or too late (risk cutting off developing buds).
How to Prune Ixora
- Deadhead spent flowers to encourage continuous flowering.
- Shape the plant by trimming stems to maintain its form and size—ideal for decorative hedges or potted houseplants.
- Thin the foliage by removing crowded or crossing branches to improve air and light access.
- Promote bushier growth by cutting out one branch at any three-way junction.
- Cut above a leaf node or bud at a 45° angle to encourage healthy new shoots.
- Use sharp, sterilized pruning shears or a hand saw for thicker branches to avoid disease spread.
Pruning Tips and Warnings
- Avoid removing more than 30% of the plant’s top growth at once.
- Don’t shear repeatedly—it can remove flower buds and reduce blooming.
- Always dispose of pruned material to deter pests and disease.
- Varieties like Ixora ‘Nora Grant’ require only light pruning.
Common Pruning Mistakes
- Over-pruning can lead to sparse foliage and stunted growth.
- Hard cutting may cause dieback and shorten the plant’s lifespan.
- Avoid cutting healthy, structural branches unless necessary.
Quick Reference Table: Ixora Pruning
| Step | Purpose | Best Time | Notes |
|---|---|---|---|
| Deadheading | Promote more blooms | After flowering | Pinch or cut spent flowers |
| Shaping | Maintain plant size and appearance | Spring/post-bloom | Trim to desired form |
| Thinning | Improve airflow and disease control | Spring/post-bloom | Remove crowded branches |
| Strategic | Stimulate bushier growth | Spring/post-bloom | Cut one of three at a joint |
With regular pruning, your Ixora will remain lush, healthy, and blooming beautifully throughout the year—perfect for both indoor plant displays and vibrant outdoor landscapes.
Ixora Care and Maintenance
- Pruning: After flowering, pinch off spent blooms (deadheading) to encourage more flowers
- Shaping: Light pruning helps maintain shape and size, especially for hedges or potted forms
- Repotting: Every 2–3 years to refresh soil and avoid root-bound conditions
Common Ixora Pests and How to Treat Them
While Ixora is relatively pest-resistant, you should watch out for:
| Pest | Symptoms | Treatment |
|---|---|---|
| Aphids | Sticky leaves, curled edges | Insecticidal soap or neem oil |
| Mealybugs | White cottony residue | Wipe with alcohol, spray with neem |
| Soft Scales | Yellowing leaves | Horticultural oil spray |
| Nematodes | Root damage | Mulch and avoid overwatering |
Popular Ixora Varieties
There are over 500 species of Ixora, with a wide range of colors and sizes. Some of the most popular cultivars include:
‘Maui’ – A dwarf variety with bright orange flowers, known for its cold tolerance.
‘Nora Grant’ – Produces striking hot pink pom-pom-like flowers.
‘Herrera’s White’ – One of the few Ixora cultivars with white blooms.
‘Super King’ – Features large clusters of deep red flowers.
‘Singapore Yellow’ – Produces yellow flowers, with the regular ‘Singapore’ boasting scarlet red flowers.
Common Problems and Solutions
1. Leaf Drop
Cause: Exposure to drafts, sudden temperature changes, or incorrect watering. Solution: Keep the plant in a stable environment, avoiding temperature fluctuations.
2. Dark Spots on Leaves
Cause: Alkaline soil leading to micronutrient deficiencies (iron and manganese). Solution: Use acidic soil and apply chelated micronutrient foliar spray.
3. Pests (Aphids, Mealybugs, Scale)
Cause: Poor airflow and excessive moisture. Solution: Apply insecticidal soap or neem oil and improve air circulation.
4. Lack of Blooms
Cause: Insufficient sunlight, over-fertilization, or incorrect pruning. Solution: Ensure at least 6 hours of direct sunlight, avoid excessive nitrogen-rich fertilizers, and prune correctly.
