Mahogany (Swietenia mahagoni), also known as West Indian or small-leaf mahogany, is a stately tropical hardwood tree that has become a popular timber and avenue species across much of India. It develops a tall, straight trunk topped by a broad, rounded crown of glossy pinnate leaves, offering excellent shade in parks, farms and large gardens.
In Indian conditions it grows quickly once established and tolerates heat, occasional drought and a wide range of soils, making it a favourite for commercial timber plantations as well as ornamental landscaping. Small greenish-white flowers appear in flushes and are followed by large woody, pear-shaped capsules that split open to release winged seeds.
The tree is valued both for its high-quality, durable, richly grained wood and for its low-maintenance, long-lived presence in the landscape. It is best suited to open ground rather than small pots, though young plants are sometimes container-raised before transplanting.

Care guide
| Sunlight |
Full sun; needs 6+ hours of direct light for strong, straight growth |
| Watering |
Water regularly for the first 1-2 years to establish; mature trees are drought-tolerant and need little extra water |
| Soil / mix |
Adapts to most well-drained soils including loam, sandy and slightly alkaline soils; avoid waterlogging |
| Temperature |
Thrives at 20-38 C; tolerates Indian summer heat but is sensitive to frost |
| Humidity |
Prefers moderate to high humidity; adapts well to coastal and plains climates |
| Fertilizer |
Apply well-rotted FYM or compost at planting; feed young trees with a balanced NPK 1-2 times a year for faster growth |
| Pruning |
Remove dead, crossing or low branches in early years to train a single straight trunk; little pruning needed once mature |
| Repotting |
Field-grown; pot-raised saplings should be transplanted to open ground within 1-2 years before they become root-bound |
| Propagation |
Mainly from fresh seed; soak seeds and sow in nursery bags, germination in 2-4 weeks |
| Pests & problems |
Generally hardy; watch for leaf-eating caterpillars (shoot borer), and occasional scale or mealybug on young plants |
| Difficulty |
Easy |
Uses
<ul><li>Premium reddish-brown timber for furniture, plywood, panelling and musical instruments</li><li>Fast-growing shade and avenue tree for roadsides, parks, farms and large gardens</li><li>Commercial agroforestry and timber plantation crop in many Indian states</li><li>Windbreak and boundary planting on farmland</li></ul>
Growing tips
<p>Plant saplings at the onset of the monsoon (Jun-Jul) so the rains help establish a strong root system with minimal irrigation.</p><p>Choose an open, sunny site with at least 4-5 m clearance from buildings and drains, as the tree grows large with spreading surface roots. Stake young plants and prune lower branches in the first 2-3 years to encourage a tall, straight, timber-quality trunk.</p><p>Water deeply but infrequently during the first two summers; once established the tree is highly drought-tolerant. Protect young plants in regions that experience winter frost.</p>
