Introduction to the mahogany tree
The mahogany tree, belonging to the Meliaceae family, is recognized worldwide for both its imposing appearance and the quality and beauty of its wood. Scientifically known as Swietenia macrophylla, is native to the intertropical regions of America, extending from Mexico to Brazil and Bolivia. This species not only excels in the timber industry but also possesses significant ecological, ornamental, and cultural value, becoming a key element of tropical rainforest biodiversity and a national symbol in several countries.
Mahogany encompasses several species within its genus, which share similar morphological characteristics and uses, but differ depending on their geographic distribution and ecological adaptations. Their unique characteristics, longevity, and the value of their timber resources have driven both the cultivation and protection of these trees, especially in the face of challenges such as deforestation and illegal trade.
Taxonomy and etymology of mahogany
- Kingdom: Plant
- Division: Magnoliophyta
- Class: Magnoliopside
- Order: sapindales
- Family: meliaceae
- Gender: swietenia
- Main species: Swietenia macrophylla King
Name swietenia was awarded in honor of the physician Gerard van Swieten, while macrophylla It means "with large leaves" in Latin, referring to the remarkable size of its leaves. In addition, various regions and cultures know mahogany by numerous common names: big-leaf mahogany, American mahogany, palo santo, mogno, mara, among others.
Geographic distribution and natural habitat
Mahogany is native to tropical America, naturally distributed from southern Mexico, throughout Central America, and as far away as parts of the Amazon in Brazil and Bolivia. Its habitat extends through large humid and subhumid forests, at altitudes ranging from sea level to approximately 1500 meters. Ideal conditions include warm climates, high annual rainfall (from 1000 to 5000 mm), average temperatures of 23°C to 28°C and deep, fertile, well-drained soils, preferably sandy-loam to clayey in texture.
Mahogany is able to adapt to variations in soil moisture and exhibits some shade tolerance during its juvenile stage. This species thrives in areas where it competes for sunlight and is often found as an emergent individual above the tropical forest canopy, playing a vital role in the ecological dynamics of these regions.
Morphological characteristics of the mahogany tree
Height and carriage
El mahogany tree It can reach remarkable heights, typically between 25 and 50 meters, although in optimal conditions it can reach up to 60 meters. The trunk is straight, cylindrical, and branchless for much of its height, with diameters easily reaching 150 cm and, in very old specimens, even up to 200 cm.
Trunk and bark
The trunk is straight, robust and with well-developed buttresses, especially at the base, which provides stability. Its outer bark is reddish-brown, with deep fissures; the inner bark ranges in color from pink to reddish, and is often fibrous, bitter, and rich in tannins and resins.
Cup
The mahogany's canopy is broad and open, like an umbrella or fan, with higher branching and strong, ascending limbs. This architecture allows light to reach the upper leaves while competing with other trees in the forest.
Leaves
The Mahogany leaves are alternate and paripinnate, large (15–40 cm long), composed of 6–12 lanceolate leaflets, shiny on the upper surface and paler on the underside. Their texture is leathery, and the margins are entire. When mature, they are deep green, giving the tree a glossy appearance.
Flores
The flowers of the mahogany are hermaphrodites, small and fragrant, grouped in axillary panicles 10 to 20 cm long. The petals are whitish or greenish, oval in shape, and have five yellow stamens. Its pollination system depends mainly on insects.
Fruits and seeds
The fruit is a woody capsule, ovoid or oblong, reddish-brown in color, ranging in size from 12 to 25 cm long and up to 12 cm in diameter. When ripe, it splits into four or five valves to release numerous winged seeds (samaras), very light and cinnamon-colored, which are effectively dispersed by the wind (anemochory).
Life cycle, growth and reproduction
- Longevity: Over 60 years old; some specimens can live for several centuries, depending on environmental conditions and forest management.
- Flowering: It generally occurs during the transition from the dry to the wet season. The tree reaches reproductive maturity and begins to flower between 12 and 15 years of age.
- Fructification: It occurs a few months after flowering, releasing seeds that germinate mainly at the beginning of the rainy season.
- Spread: Mainly sexual through seeds with high germination power, although its cultivation in nurseries allows the establishment of controlled plantations.
Seedlings require good light to thrive, although they tolerate some shade in their juvenile stages. The growth of young trees can be accelerated if they compete for light, as is the case when planting mahogany trees in areas shaded by other tall trees.
Properties of mahogany wood
La mahogany wood It is one of the most valued and appreciated globally for its exceptional characteristics:
- Color: Reddish-brown heartwood, which darkens over time, acquiring a shiny appearance when polished.
- Texture: Medium, with straight to slightly crossed grain, sometimes variegated.
- Hardness: Medium to hard, though surprisingly easy to work with.
- Veining: Attractive figure and very smooth and shiny surface to the touch.
- Apparent density: 0.45 to 0.60 g/cm³.

Cultivation, planting and management processes
Seed collection and processing
Mahogany seed production is abundant. The fruits must be harvested directly from the tree before they open, using safe techniques to avoid damage. Once harvested, they are dried to facilitate opening the capsules and extracting the seeds.
- La germination It usually begins one or two weeks after sowing and can reach percentages of 80 to 95%. Seeds can be stored in cool, dry conditions for long periods without losing viability.
- El nursery cultivation It requires deep, well-drained soils, providing partial shade to young seedlings.
Planting and silvicultural recommendations
- Mixed plantings with other fast-growing species (such as teak, leucaena, or guanacaste) help protect young mahogany shoots, which are susceptible to pest attack.
- El recommended spacing It is 5 to 6 meters between plants, which allows the development of straight trunks and wide crowns.
- The first few years require rigorous weed control and frequent thinning to select the best specimens.
Pest and disease management
The main threat to mahogany is the moth Hypsipyla grandella, known as the bud borer, which particularly affects young shoots and seeds. For its control, integrated management is recommended, avoiding pure plantations and preferring agroforestry methods. Other pests include borers of the genus platypus and some mushrooms.
