Banyan Tree
Ficus benghalensis
📖 About this plant
The Banyan Tree (Ficus benghalensis), known as bargad in Hindi, alamaram in Tamil, and the national tree of India, is a magnificent evergreen fig tree in the Moraceae family, famous for its extraordinary aerial prop roots that grow downward from branches, take root in the ground, and become secondary trunks — allowing a single banyan to spread over an enormous area and live for centuries. Native to the Indian subcontinent, the banyan has been revered in Indian culture for over 4,000 years — it features prominently in Hindu, Buddhist, and Jain scriptures. Lord Krishna is said to have rested under a banyan leaf, Buddha is said to have meditated under one before enlightenment, and the banyan is the national tree of India. The largest known banyan, Thimmamma Marrimanu in Andhra Pradesh, covers over 19,000 sq m (almost 5 acres) with over 1,000 prop trunks — making it one of the largest single organisms by canopy area on Earth. The famous Howrah Great Banyan in the Kolkata Botanical Garden is over 250 years old with 3,300+ prop roots. The banyan is also a keystone ecological species — its small red figs (which are actually inverted flowers called syconia) are eaten by birds, monkeys, bats, and squirrels, and the tree provides habitat for countless animals, insects, and epiphytes. In Ayurvedic medicine, the bark, leaves, aerial roots, and latex are all used — for diabetes, diarrhea, skin diseases, and as an astringent. The leaves are also used as fodder and plates (in traditional Indian feasts). The banyan is the original “tree of life” — the word “banyan” comes from the Gujarati banias (merchants), who conducted their business under its shade (the Portuguese anglicized it to “banyan”).

💡 Care tips
- Plant in full sun in any well-draining soil — the banyan is exceptionally tough and drought-tolerant once established. Give the tree PLENTY of room — never plant near buildings, walls, paved paths, or underground pipes (aggressive roots will damage all of these). The banyan needs space for its canopy to spread and for aerial prop roots to develop. Plant as a standalone specimen in a park, large garden, farm boundary, or temple courtyard. Water deeply when young (first 2-3 years); once established, the tree is remarkably drought-tolerant. Fertilize lightly in spring/monsoon with balanced NPK. The tree grows rapidly when young — 1-2 m per year — and reaches mature size in 20-30 years. Aerial prop roots develop from horizontal branches as the tree matures — these grow downward, thicken, and become secondary trunks, allowing the tree to spread indefinitely. To encourage prop root formation, do not prune them off — they are essential to the tree's character and structural support. Prune only dead/damaged branches. In small gardens, the banyan can be grown as a bonsai (it is one of the most popular Ficus species for bonsai). Propagate from cuttings (cuttings of even large branches root easily in monsoon), seeds (from ripe figs), or aerial layering. Note: the banyan is sacred in Indian culture — never cut one without proper respect. In urban India, banyans are often preserved as protected "temple trees" — the focal point of village life for centuries.
