Mosambi, also known as sweet lime or sweet lemon (Citrus limetta), is a small evergreen citrus tree widely cultivated across India for its round, smooth-skinned fruit. The pale green to yellow fruit yields a mild, low-acid juice that is hugely popular at Indian juice stalls and is often recommended during recovery from illness for hydration and vitamin C.
The tree is compact and bushy with glossy aromatic leaves and fragrant white blossoms, making it equally suited to home gardens and large terrace pots. It thrives in India's warm tropical and subtropical climates, with major commercial cultivation in Maharashtra, Andhra Pradesh, Telangana, and Punjab.
Hardy and relatively undemanding once established, Mosambi rewards growers with abundant crops, fragrant flowers, and attractive evergreen foliage year after year.

| Humidity |
Adapts to moderate humidity; tolerates dry heat if watered well |
| Fertilizer |
Feed with well-rotted manure plus NPK 2-4 times a year; add micronutrients (zinc, iron) to prevent leaf yellowing |
| Pruning |
Light pruning after harvest to remove dead, crossing, and water-shoot growth; keep centre open for airflow |
| Repotting |
Repot container plants every 2-3 years into a larger pot with fresh, fertile, well-draining mix |

Uses
Mosambi is grown mainly for its refreshing, mildly sweet fruit:
- Fresh juice (a staple at Indian juice stalls), squashes, and sherbets
- Eaten fresh as a low-acid, easy-to-digest fruit
- Often recommended for hydration and vitamin C during fever and convalescence
- Fragrant flowers and evergreen foliage make it an attractive garden and terrace plant
Growing tips
Plant Mosambi at the start of the monsoon (June-July) or in early spring so roots establish before extreme heat. Choose a sunny, well-drained spot and add plenty of compost or farmyard manure.
Water deeply during the dry, hot months (Mar-Jun) and at fruit set, but cut back during heavy rains to prevent root rot. Mulch the base to conserve moisture. Apply zinc and iron sprays if leaves turn yellow between the veins. Protect young plants from cold winter winds in North India.
