🔴 Overview & Botanical Profile
Red Sandalwood (Pterocarpus santalinus Linn. f.) is a medium-sized deciduous tree endemic to the southern Eastern Ghats of India. It belongs to the family Fabaceae (legume family) — notably DIFFERENT from White Sandalwood (Santalaceae). It is valued primarily for its deep blood-red heartwood, santalin pigment, and medicinal properties.

- Flowers: Bright yellow, in racemes, April–May
- Pods: Woody, orbicular wing, 4–5cm diameter, indehiscent
- Wood: Deep blood-red to reddish-brown heartwood; pale yellow sapwood

Natural Distribution
- Native to: Cuddapah, Kurnool, Chittoor districts of AP; Kadapa, Nellore hills
- Also found in: Nallamalai Hills, Velikonda Range, Palakonda Range
- Elevation: 200–900m in rocky, dry deciduous forests
- Now being cultivated in Maharashtra, Odisha, Karnataka, Tamil Nadu
⚠️
Conservation Status: Red Sandalwood is classified as Endangered on the IUCN Red List due to illegal logging and over-exploitation. Private cultivation is encouraged to reduce pressure on wild populations, but strict regulations apply to trade.
🌡️ Climate Requirements
Red Sandalwood is adapted to the dry deciduous forests of the Eastern Ghats. It is significantly more drought-tolerant than White Sandalwood.
Annual Rainfall
400–1000mm
Drought Tolerance
Very High
Frost Tolerance
Moderate (more than white)
Suitable Regions in India
- Best: Andhra Pradesh (native habitat) and Telangana
- Very Good: Tamil Nadu dry zones, Odisha Eastern Ghats
- Good: Maharashtra, Karnataka, Rajasthan (with irrigation)
- Prefers semi-arid to sub-humid tropical climate
- Grows well in rocky, degraded lands — ideal for land reclamation
🌱 Soil Requirements
Best Soils
Rocky laterite, shallow gravelly
Drainage
Well-drained essential
Depth
Shallow soils acceptable
- Grows naturally on rocky, shallow, red laterite soils
- Actually thrives on degraded or marginal lands — good for land reclamation
- Deep rooted — can access moisture from deeper soil layers
- Tolerates low fertility soils better than White Sandalwood
- Avoid waterlogged or heavy clay soils
- As a legume (Fabaceae), it fixes atmospheric nitrogen — improves soil fertility
💡
Land Reclamation: Red Sandalwood is excellent for reclaiming degraded, eroded, or marginally fertile lands. It improves soil structure over time through its nitrogen-fixing capacity and deep root system. This makes it particularly valuable for dry wastelands.
🌱 Plantation Guide
Planting Season
June–August
No Host Plants Needed!
Unlike White Sandalwood, Red Sandalwood grows completely independently. This makes cultivation simpler and more straightforward. Companion planting with other drought-tolerant species is recommended for better ecosystem management but not mandatory.
Planting Steps
- Site selection: Well-drained, sloping land preferred; avoid low-lying areas
- Dig pits 60×60×60cm; fill with native soil + 10% FYM + river sand
- Transplant nursery-grown seedlings (6–12 months old) at monsoon onset
- Water immediately after planting; drip irrigation recommended
- No shade needed after transplanting — full sun preferred from the start
- Initial irrigation: 3 times/week for 3 months, then gradually reduce
- Growth rate: Moderate — 30–50cm height growth per year
🌿 Fertilizer Management
Red Sandalwood is a legume that fixes nitrogen. It generally requires less fertilization than most commercial crops.
Establishment (Yr 1–3)
FYM 8kg + SSP 50g
Growth (Yr 4–8)
FYM 10kg + Phosphorus
Mature (8yr+)
Minimal — organic only
- Being a legume, Red Sandalwood fixes its own nitrogen — reduce N fertilizer
- Phosphorus fertilization improves nodulation and wood density
- Apply FYM annually in September–October (pre-winter)
- Zinc sulfate (15g/tree) if deficiency observed
- Rock phosphate application every 3 years beneficial for wood quality
🔬 Diseases & Pests
Red Sandalwood is relatively hardy but can suffer from certain diseases, especially in poorly-drained conditions.
Common Diseases
- Root rot (Fusarium/Phytophthora): In waterlogged soils. Treat with Metalaxyl 0.2% drench + improve drainage
- Heart rot (Ganoderma species): Fungal decay of wood. Prevent with proper spacing and wound treatment
- Leaf blight (Alternaria): Spray Mancozeb 2.5g/L in humid conditions
- Die-back: Branch tip dieback due to Lasiodiplodia — remove and apply Bordeaux paste
Common Pests
- Bark borer: Inject Monocrotophos into bore holes; swab with Carbaryl paste
- Leaf-eating caterpillars: Spray NEEM oil 0.5% or Chlorpyrifos 0.05%
- Termites: Chlorpyrifos 2ml/L soil drench; neem cake 200g/plant
- Cattle/deer: Fence plantation for first 5 years; young trees are vulnerable
✅
Good News: Red Sandalwood does NOT suffer from Spike Disease (phytoplasma) which is the most feared disease of White Sandalwood. This is a significant advantage for farmers choosing Red Sandalwood.
🪓 Harvesting Guide
Yield/Tree
50–200 kg timber
Heartwood Color
Deep blood red
Harvesting Approach
- Unlike White Sandalwood, Red Sandalwood timber (not just heartwood) is valuable
- Trees can be harvested by felling (not necessarily uprooting)
- Grade timber by heartwood-to-sapwood ratio and color intensity
- Darker red = more valuable; sapwood (pale) has much lower value
- Obtain felling permission from Forest Department before harvesting
- In AP/Telangana: PCCF approval required due to endemic + endangered status
- Transit pass mandatory — especially strictly enforced for red sandalwood
⚠️
Strict Enforcement: Red Sandalwood is subject to much stricter enforcement than White Sandalwood due to high smuggling rates (primarily to Japan, China, and South Korea). Always have all documents ready when transporting even small quantities.
⚖️ Legal Requirements (STRICTER than White Sandalwood)
🔴
High Alert: Red Sandalwood is one of the most-smuggled natural resources in India. The Forest Department and police conduct anti-smuggling operations regularly in AP and Telangana. Even private cultivators face scrutiny during transport. Ensure ALL documents are in perfect order.
Key Legal Requirements
- Register plantation with Forest Range Officer within 6 months of planting
- Felling permission required — from DFO (white) or PCCF (red, in AP/Telangana)
- Transit pass: GPS-tracked in some districts of AP/Telangana
- Export: CITES permit + DGFT license mandatory
- Ownership certificate from Forest Department for all private holdings
