Ixora, often known as flame of the woods, is a tropical shrub known for its clusters of star-shaped flowers and glossy green leaves. It’s a staple in Florida landscapes for its continuous blooming and the variety of colors it offers, such as red, pink, orange, and yellow.
Planting
- Location: Ixora thrives in full sun to partial shade. They flower best in full sun but appreciate some afternoon shade in the hottest parts of the summer to prevent leaf scorch.
- Soil: Plant in well-draining, acidic soil with a pH between 5.0 and 5.5. Ixora struggles in alkaline soil, which can cause chlorosis (leaf yellowing) due to iron deficiency.
- Spacing: Space plants 2 to 4 feet apart, depending on the variety, to ensure good air circulation and room for growth.
Watering
- Frequency: Water regularly to keep the soil evenly moist, especially during the hot and dry periods typical of Southwest Florida. Ixora does not tolerate drought well.
- Method: Apply water directly to the soil at the base of the plant, avoiding overhead watering to reduce the risk of fungal diseases.
Fertilization
- Schedule: Fertilize Ixora every two to three months during the growing season with a fertilizer formulated for acid-loving plants. This helps maintain the acidic soil conditions they prefer and supports flowering.
- Application: Apply fertilizer around the drip line of the plants rather than directly at the base to avoid root burn and ensure nutrients are absorbed effectively as water spreads.
Pruning
- Timing: Prune in late winter or early spring to maintain shape and promote bushier growth. Pruning after a bloom cycle can also encourage additional flowering.
- Purpose: Regular pruning helps control the size of the plant, removes dead branches, and encourages healthier, denser foliage and more blooms.
Pest and Disease Management
- Common Pests: Ixora can be susceptible to pests like spider mites and aphids, especially when stressed or in dry conditions.
- Disease Prevention: To prevent fungal diseases, ensure good air circulation around plants and avoid wetting the foliage. Mulch around the base to retain moisture and reduce weed competition, but keep the mulch away from the plant stems to avoid rot.
Tips for Maximum Blooms
- Light Exposure: Ensuring that Ixora gets at least 4-6 hours of direct sunlight will maximize blooming.
- Proper Soil pH: Maintaining the correct soil pH with appropriate fertilizers and soil amendments is crucial for preventing nutrient deficiencies and promoting vibrant blooms.
Winter Care
- Protection: While Ixora is generally hardy in Southwest Florida, during unusually cold winters, protect the plants with frost cloth or move potted specimens to a sheltered location.
- Watering: Reduce watering frequency in the winter as the plant’s growth slows, but do not allow the soil to become completely dry.
