Best used for
- Canal-side, riverside and low-lying corridor alignments
- Large campuses and parks with space for a genuinely big tree
- Carbon and biodiversity plantings where longevity matters
- Bank stabilisation adjacent to water bodies
Avenue tree
Arjuna
A large, buttressed native with smooth pale bark and a spreading canopy — the best avenue tree for moist alignments, riverbanks and canal-side roads.
About Arjuna
Terminalia arjuna is the tree to plant where there is water and space. Along canals, drains, riverside roads and campus lakes it grows into a magnificent pale-barked specimen with a wide, high canopy and an unusually long life, and its roots hold banks in a way that engineered solutions rarely match at the same cost.
On road projects it is under-specified because planners default to neem everywhere. On the moist stretches of an alignment — the canal crossing, the low chainage that ponds every monsoon — arjuna will outperform neem comfortably, and a corridor that switches species by soil moisture looks and performs better than a monoculture.
It is also a serious carbon and biodiversity asset: large biomass, long life, and a host plant for the antheraea silk moth. On projects with compensatory plantation or ESG reporting obligations, that matters.
Do not use where
- Narrow verges and medians — the buttress and spread will outgrow them
- Arid low-rainfall corridors without irrigation
- Close proximity to structures and boundary walls
| Botanical name | Terminalia arjuna |
|---|---|
| Family | Combretaceae |
| Also called | Arjun, Kahua, Marudham |
| Mature height | 20–25 m |
| Spread | 12–18 m |
| Growth rate | Moderate |
| Sunlight | Full sun |
| Water need | Moderate to high; naturally a riverbank species |
| Soil | Prefers deep alluvial and moist loam; tolerates seasonal flooding better than most avenue trees |
| Climate | Sub-humid to humid tropics across most of peninsular and northern India |
| Flowering | Pale yellow-white spikes, April–June; winged fruit thereafter |
| Spacing | 10–12 m on centre — this tree needs room |
| Planting window | June–August |
| Establishment | 2–3 monsoons |
| Maintenance | Low |
| Pollution tolerance | High |
| Drought tolerance | Moderate |
| Transplanting | Moves reasonably at small girth in monsoon; large specimens are difficult owing to the buttressed base. |
Care
Season-by-season care calendar
| Season | What to do |
|---|---|
| February–March | Formative pruning of young trees. Clear the base of competing growth — arjuna resents competition in its first years. |
| April–June | Irrigate weekly through the first three summers. This species is far less drought-hardy than neem in youth. |
| July–September | Prime planting window. Ensure basins drain — arjuna tolerates seasonal flood, not permanent stagnation. |
| October–January | Inspect for structural defects and remove crossing limbs before the canopy is too high to reach cheaply. |
Troubleshooting
Common problems and what causes them
| Symptom | Cause | Fix |
|---|---|---|
| Slow start with sparse leaf | Dry soil in the establishment years | Increase basin irrigation and mulch. This species is honest about water — give it water and it accelerates. |
| Leaf-eating caterpillar defoliation | Seasonal Antheraea and other lepidopteran feeding | Usually cosmetic; trees releaf. Intervene only if repeated in consecutive seasons on young stock. |
| Buttress roots lifting adjacent paving | Planted too close to hard edges | Site 6 m or more from paving. On existing conflicts, use flexible paving details rather than root cutting, which destabilises a big tree. |

Wedelia
Sphagneticola trilobata
The fastest green cover in Indian landscaping — a yellow-flowered creeper that blankets slopes and bed edges in months, and needs a hard edge because it will not stop.

- MaintenanceModerate — mostly containment
Arjuna — frequently asked questions
Is arjuna suitable for highway plantation?
Yes, on moist alignments with adequate verge width. It is not a median tree and not a species for arid corridors without irrigation.
How long does arjuna live?
Well over a hundred years in favourable sites, which makes it a genuine legacy tree for campuses and public parks.
Does arjuna have medicinal value?
The bark has a long history in Ayurveda, principally for cardiac use. That is context, not a landscape specification reason — plant it for its form, longevity and bank stabilisation.
