Sunlight Needs:

Full sun is essential. This tree thrives in bright, direct sunlight and will bloom more heavily with 6–8 hours of daily exposure.

Watering Requirements:

Highly drought-tolerant once established. During the first growing season, water deeply but infrequently to help develop a strong root system. Afterward, very little supplemental watering is needed—making it ideal for water-wise or xeric gardens.

Soil Preferences:

Prefers well-drained soils—especially sandy, rocky, or limestone-based substrates. Tolerates poor soils and is salt and heat-tolerant, making it a great fit for coastal and inland South Florida landscapes.

Fertilization:

Generally not necessary due to its natural nitrogen-fixing abilities. However, a light application of balanced fertilizer in early spring can support new growth if needed.

Pest & Disease Resistance:

Very resilient to pests and diseases. Occasionally may attract scale or leaf beetles, but rarely requires intervention in healthy conditions.

Maintenance & Pruning:

Low maintenance. Prune in late winter or early spring to shape the canopy or remove dead wood. Be mindful of thorns when planting near foot traffic areas.

Why It Works in South Florida:

• Heat and drought-resistant—perfect for xeriscaping

• Grows well in sandy, poor, or coastal soils

• Produces long-lasting yellow blooms that support pollinators

• Low-maintenance, nitrogen-fixing, and fast-growing
