Hamelia patens thrives in warm climates and is frost-sensitive. It grows best in USDA hardiness zones 9b to 11, where the temperature ranges from 25°F (-4°C) to 50°F (10°C). It can tolerate high temperatures up to 100°F (38°C) but needs protection from direct sunlight during the hottest part of the day.
Hamelia patens prefers well-drained soil that is rich in organic matter. It can grow in a variety of soil types, including sandy loam, clay loam, and rocky soil. The soil pH should be between 6.0 and 7.5.
Hamelia patens requires regular watering, especially during the growing season. The soil should be kept moist but not waterlogged. It can tolerate short periods of drought but may lose its leaves in prolonged dry spells.
Hamelia patens prefers full sun but can also grow in partial shade. It needs at least 6 hours of direct sunlight per day to produce flowers.
Hamelia patens benefits from regular fertilization with a balanced fertilizer, such as a 10-10-10 or 20-20-20 formula. Fertilizer should be applied every 2-3 months during the growing season.
Hamelia patens can be pruned to maintain its shape and size. Pruning should be done in late winter or early spring before the new growth appears.
