About Big-leaf mahogany
Swietenia macrophylla, commonly known as Big-leaf Mahogany or Honduras Mahogany, is a majestic and fast-growing tree, valued for its high-quality timber and imposing stature. It can reach impressive heights, developing a dense canopy and a straight trunk. It is ideal for large open spaces, parks, and reforestation projects, where its shade and presence can be fully appreciated.
Native range
Central and South America, from southern Mexico to Brazil and Bolivia
Care tips
It requires full sun for optimal growth, although it tolerates some partial shade in its juvenile stages. Watering should be regular during its first few years to establish, reducing once mature, as it is tolerant of drought periods. It prefers deep, well-drained, and fertile soils, avoiding waterlogging. A common mistake is planting it in confined spaces, as it needs ample room to develop its root system and large size.
