The Sal tree, scientifically known as Shorea robusta, is a large, deciduous tree native to the Indian subcontinent and Southeast Asia. Revered for its timber, resin, and cultural significance, it plays a key role in ecology and human culture.
Sal trees are commonly found throughout India, Nepal, Bhutan, Bangladesh, and Myanmar. They thrive in tropical and subtropical climates, often in moist deciduous forests, river valleys, and lowland plains.
Sal trees have tall, straight trunks, spreading crowns, and large, leathery leaves with serrated margins. They produce small, fragrant yellowish-white flowers followed by winged seeds dispersed by wind.
Sal trees can grow up to 30–35 meters (98–115 feet) tall, with a straight cylindrical trunk and broad spreading crown, providing shade and habitat for wildlife.
The scientific name is Shorea robusta, belonging to the Dipterocarpaceae family. “Shorea” honors botanist Sir John Shore, and “robusta” indicates the tree’s sturdy nature.
Sal trees bloom in spring, producing small, fragrant flowers that attract bees, butterflies, and other pollinators. Flowering varies with local climate conditions.
Plant in well-drained soil with full sunlight. Water regularly during dry periods, mulch to retain moisture, and prune dead or diseased branches to maintain growth.
Provides timber for construction, furniture, and fuelwood, enhances forest biodiversity, supports local livelihoods, and holds cultural/religious significance.
Due to their large size, Sal trees are not commonly planted in urban areas but can be used in parks, botanical gardens, and large green spaces.
From seeds or cuttings. Sow mature seeds in well-drained potting mix, or root semi-hardwood cuttings in rooting hormone solution for best results.
Defoliating insects, bark beetles, wood borers, leaf spot, and root rot are common. Thinning, pruning, and monitoring help prevent damage.
Moderately drought-tolerant once established, but young trees benefit from regular watering. Mulching helps retain soil moisture.
Several decades to reach full height and girth. However, they can provide timber within 50–60 years of planting.
Yes, Sal trees shed their leaves seasonally, turning yellow or reddish before falling, creating a colorful forest floor.
No, they require ample space for root development. Best planted in the ground in spacious, well-drained locations.
Sal trees are valued for majestic form, attractive foliage, and cultural importance. They are ideal as shade, avenue, or specimen trees in parks and botanical gardens.
No, they are native to South Asia and generally not invasive, though they may naturalize in favorable disturbed habitats.
Prune in late winter or early spring to remove dead/diseased branches, improve air circulation, and maintain shape. Use clean, sharp tools for best results.
Sal trees can live for several centuries under optimal conditions. Some specimens are over 1,000 years old. Proper care prolongs their lifespan.
Sal trees are not generally listed as protected, but conservation and sustainable forestry ensure their continued existence and ecological importance.
