Arjun tree is a large deciduous tree that can grow up to 30 m in height. It has a wide, spreading crown and a trunk up to 2 m in diameter. The bark is dark brown to black in colour and is smooth or finely fissured. The leaves are simple, alternate and oblong-lanceolate in shape. They are 10-20 cm long and 2-6 cm wide. The flowers are small, white or yellowish-white in colour and borne in axillary or terminal panicles. The fruits are oval or oblong in shape, 3-5 cm long and 2-3 cm wide. They are yellow or greenish-yellow in colour and have a hard, woody endocarp.
How to care:
Arjun tree needs full sun and well-drained soil for optimal growth. It is tolerant of drought and can grow in poor quality soils. However, it does not tolerate waterlogging. The tree should be given a deep watering at least once a week during the summer months. It should be fertilized with a balanced fertilizer once a month during the growing season. The tree should be pruned regularly to maintain its shape and size.

Arjun tree can be propagated from seed or from cuttings. Terminalia arjuna can be propagated by seed, and also by root-suckers, stumps and air-layering. Average 1000 seed weight is 1408 g.Natural regeneration rarely occurs in semi-arid habitats due to lack of sufficient moisture. Seeds germinate early in the rainy season. Sun-exposed seeds germinate less-readily. Seeds are soaked in hot water for 1 minute and left in cold water for 48 hours before sowing. Direct sown plants tolerate mid-season drought better than nursery seedlings, although irrigation is needed for prolonged periods of drought. Seed germination usually lasts between 50–75 days and the germination rate is 5–50%. Nursery raised seedlings transplant well. Young seedlings do not tolerate drought and frost well, and prefer full sunlight provided the ground is moist.
Pests and diseases:
The tree is susceptible to powdery mildew, leaf spot and root rot.
Arjun tree is often planted as an ornamental tree in parks and gardens. It is also used for shade and windbreaks.
