Rudraksh Tree (Elaeocarpus sphaericus): Where It Grows in India and How to Plant It

Rudraksh is native to the West and East Himalaya, Nepal, Assam, Bangladesh and Myanmar. A scientific review describes it as needing a humid to warm climate, preferably partial shade, and temperatures of about 10–30 °C, and also records it from the Gangetic Plain, Madhya Pradesh, Bihar and the Konkan Ghats. In the forests of Arunachal Pradesh it grows under taller trees.

How it suits each part of India:

• Grows well: North-East India and the lower, warmer Himalayan hills, its native home.
• With care: the east, where the humid climate suits it but it still needs partial shade; the west coast, on well-drained land with some shade; and the northern plains, central India, the east coast and the southern peninsula, where it needs shade and protection from the dry summer heat.
• Hardest: hot, dry regions such as the north-west dry zone, with very low humidity before the monsoon, summer highs above 45 °C with hot loo winds, and alkaline soil. It can survive there only in a shaded, sheltered, irrigated spot.

Rudraksh prefers moist, well-drained, clayey or loamy soil that is slightly acidic to neutral (pH about 6.0–7.3), and struggles in alkaline soil.

Shade is not optional. In a study published in Tropical Ecology, Rudraksh seedlings survived and grew better under dense tree cover than in open sites, and disease attack was highest in the open. The researchers recommended planting it under established trees or in slightly shaded spots.

Rudraksh has been grown in hotter, drier parts of central India, but with care. In Indore, a sapling planted in 2005 at a private home was about 15 ft tall and fruiting by 2009; the owner protected it with shade cloth in summer. In Jabalpur, two trees at the State Forest Research Institute grew to over 30 ft in about 8 years and fruit in alternate years. We found no documented, long-term planting that has survived and fruited in the dry north-west. Nurseries sell Rudraksh plants in dry regions too, but a sale does not mean the tree will establish.

That is why GreenEye treats Rudraksh as a "special-care" tree outside its humid native range, plants it only in sheltered spots there, and does not promise beads.
