Nepali hog plum Care (Choerospondias axillaris)

Choerospondias axillaris grows best in full sun to light partial shade in most temperate to subtropical climates.

• Aim for 6–8 hours of direct sun daily, with morning sun preferred and some protection from intense mid‑afternoon summer sun in hotter regions.
• Young Nepali hog plum trees tolerate light partial shade, but prolonged shade reduces flowering, fruiting, and overall vigor.
• In cooler climates, choose the sunniest, south‑ or west‑facing site; in hot climates, provide light overhead or western-side filtering to limit leaf scorch.

This species prefers steadily moist, well‑drained soil and responds best to deep, infrequent watering.

• Let the top 3–5 cm of soil dry before watering again, then water deeply so moisture reaches the main root zone rather than just the surface.
• Reduce watering frequency in cool seasons or during dormancy, but avoid letting the soil become dust‑dry or cracked around the root area.
• Watch for yellowing, soft leaves or persistent wet soil as signs of overwatering, and for leaf edge browning, droop, and very dry topsoil as signs of underwatering in Choerospondias axillaris.

This tree is adapted to warm temperate to subtropical conditions and dislikes extended cold or extreme heat.

• Optimal growing temperatures are about 68–86°F (20–30°C), with strongest shoot and leaf growth in consistently warm, frost‑free periods.
• Mature trees can tolerate brief drops near 28–30°F (-2 to -1°C), but young plants are more tender and should be protected from any frost.
• Extended exposure above 95°F (35°C) may cause leaf scorch and stress, so provide mulch and, where possible, light shade during extreme heat waves.

This species prefers moderate ambient humidity but adapts to a broad range in most home and outdoor conditions.

• Target 40–60% humidity for young or container-grown Nepali hog plum to reduce leaf edge browning and tip dieback.
• It tolerates drier air once established, but prolonged humidity below 30% can cause leaf curl and slow growth.
• Increase humidity locally by grouping plants, using a nearby water tray, or briefly misting foliage in very dry, hot weather.

Choerospondias axillaris grows best in deep, well-aerated, moderately moist soil that drains freely.

• Use a loamy structure with a mix such as 50% garden loam, 30% coarse sand, and 20% compost to balance drainage and nutrient holding.
• Aim for slightly acidic to neutral pH, roughly 6.0–7.0, which supports nutrient availability and healthy root development.
• Improve drainage and aeration by incorporating coarse sand or fine gravel if the native soil is heavy or tends to compact.
• Avoid waterlogged clay, standing water, or very shallow, stony soil that restricts root penetration and increases root rot risk.

This tree can be grown in large containers for a limited period, mainly when young or maintained as a small specimen.

• Choose a tall, heavy container that resists tipping as the canopy size and wind exposure increase.
• Provide a very free-draining mix in a deep pot so the strong taproot and lateral roots can expand downward rather than circle tightly near the surface.
• Position the container where it will not overheat; dark, thin-walled pots can cause excessive root-zone temperature and moisture loss in full sun.

Choerospondias axillaris benefits from modest, balanced nutrition in cultivation, especially in poor soils.

• Apply a balanced NPK granular or slow-release fertilizer in early spring at half the label rate around the drip line.
• Supplement with well-rotted compost or manure once a year to improve soil structure and long-term nutrient supply.
• During the main growing season, 1–2 light applications of diluted liquid feed (1/2 strength) are sufficient.
• Stop feeding Nepali hog plum in late summer to allow wood to mature before winter and avoid soft, frost-prone growth.

Choerospondias axillaris responds well to light structural pruning to maintain a healthy, stable canopy.

• Carry out main pruning in late winter or very early spring before bud break to reduce stress and sap bleed.
• Remove dead, diseased, crossing, or inward-growing branches first to improve airflow and light penetration.
• Thin crowded shoots to maintain a single strong leader and well-spaced scaffold branches for long-term structure.
• Use clean, sharp bypass pruners or a pruning saw, making smooth cuts just outside the branch collar.

This species is usually field-grown, so focus on careful transplanting of young trees rather than frequent repotting.

• Transplant in late winter or early spring while still dormant, when soil is workable and not waterlogged.
• Look for circling roots, root-bound containers, or slowed growth in nursery stock as cues to move into the ground.
• Plant in a hole 2–3× wider than the root ball at the same depth, spreading roots outward gently to reduce stress.
• Water deeply after planting, apply a 5–8 cm mulch layer, and keep soil evenly moist for the first growing season.

Propagation of Choerospondias axillaris is most commonly done from seed, with some use of grafting for selected forms.

• Collect fully ripe fruits, then clean and dry seeds; some benefit from stratification, a cool moist period that breaks dormancy.
• Sow seeds in spring in a deep, well-drained mix, keeping the medium slightly moist and temperatures around 68–77°F.
• Use deep containers or nursery beds to accommodate strong taproot development and reduce later transplant shock.
• Graft desirable cultivars onto vigorous seedling rootstocks during late winter while plants are dormant.

Mature Choerospondias axillaris trees are moderately cold hardy and often need only minimal winter attention once established.

• In regions with freezing winters, add 5–8 cm of organic mulch over the root zone, keeping it clear of the trunk.
• Young or newly planted trees benefit from trunk wraps or tree guards to limit frost cracks and sunscald.
• Container-grown specimens in colder climates should be moved to a sheltered, frost-free but cool location for winter.
