🌱 How to Care for Black Ironwood to Prevent Aphids?

💧 How to Water

Water every 14 days during initial establishment. Once well-rooted, the plant is highly drought-tolerant and rarely needs supplemental irrigation. Avoid waterlogging—roots in permanently wet soil rot easily.

☀️ Lighting

Prefers full sun (more than 6 hours of direct light per day) for optimal development. Tolerates partial shade, but growth is even slower and the canopy less dense. It is not suitable for indoor cultivation.

🪴 Ideal Soil

Thrives in well-drained soils, including sand, limestone, and rocky substrate. It adapts to slightly acidic to alkaline pH (6.0–8.0). Avoid heavy clay soils or those with poor drainage. The preference for limestone substrate reflects its natural habitat in the rocky forests of the Caribbean and Florida.
