Sunlight Needs:
Requires full sun to thrive. Provide at least 6 hours of direct sunlight daily. In South Florida, full exposure helps ensure continuous blooms and dense growth.

Watering:
Water regularly during the establishment period. Once established, Allamanda is moderately drought-tolerant but prefers consistent moisture. Avoid soggy soil—good drainage is key.

Soil Requirements:
Prefers rich, well-drained soil with a slightly acidic to neutral pH (6.0–7.0). Amend sandy South Florida soils with compost to boost moisture retention and nutrients.

Fertilization:
Feed every 6–8 weeks during the growing season with a balanced fertilizer to encourage vigorous flowering. Liquid bloom boosters can be used occasionally for enhanced color.

Pest & Disease Tips:
Generally pest-resistant but watch for aphids, mealybugs, and caterpillars. Treat with insecticidal soap or neem oil if needed. Good airflow and proper spacing help prevent fungal issues.

Maintenance & Pruning:
Prune regularly to control shape and size, especially if used as a shrub or hedge. Can be lightly shaped throughout the year and hard-pruned in early spring to promote dense growth.

Special Notes for South Florida Gardeners:

• Cold-sensitive—protect or cover when temps dip below 40°F.

• Can be grown as a vine, trellised accent, or shaped as a compact shrub.

• Popular for poolside plantings, tropical borders, and butterfly gardens.

• Pairs beautifully with hibiscus, croton, and plumbago for layered tropical color.
