Jamun Tree (Syzygium cumini): How to Grow and Care for It in Jaipur

When to plant

Plant in July or August, after the first good monsoon rain. TNAU rates this above spring (February–March) planting, because spring-planted trees meet the May–June heat soon after and many die. Monsoon planting also gives roots about four months before the first cold nights.

Grafted or seedling?

Choose a grafted or budded sapling from a reliable nursery. Grafted trees start bearing in 6–7 years, seedling trees in 8–10, and a graft keeps the fruit quality of its mother tree.

For a dry site, ask for Goma Priyanka, developed by ICAR-CIAH at Godhra, Gujarat, for semi-arid dry-land conditions. ICAR describes it as comparatively small, with 85–90% pulp and 50–70 kg of fruit per tree from about the tenth year, and says it is already grown in Rajasthan. The large-fruited Ram Jamun is the common north Indian type.

If you raise jamun from seed, sow it fresh. ICRAF notes that seed loses its viability within about two weeks at room temperature.

Pit, spacing and guard

Dig a pit 1 m × 1 m × 1 m, ideally before the rains, and refill it with three parts topsoil to one part well-rotted farmyard manure or compost (TNAU's mix). Plant at the depth the sapling stood in its nursery bag, with the graft joint above the soil. TNAU spaces orchard trees 10 m apart each way, and ICRAF gives 12–14 m for ornamental trees, so give a single tree at least 10 m of open space. Put up a tree guard: ICRAF notes jamun is susceptible to browsing.

First-year watering (practical guidance)

• July–September: rain does most of the work. Water only after 7–10 dry days, and never let water stand around the stem.
• October–November: every 7–10 days.
• December–February: every 15–20 days, plus a watering before a forecast cold night. TNAU notes that winter irrigation helps protect against frost.
• March–June: every 5–7 days, early morning or evening, under a thick mulch. These months decide whether the plant survives.

Sandy soil dries faster; a plant on a watered lawn may need less.
