Factors Favoring Santalum album Growth in the Philippines:
- Climate Compatibility – Santalum album thrives in warm, tropical to subtropical climates. The Philippines’ temperature range (25–35°C) is within the ideal range for sandalwood.
- Soil Adaptability – It grows well in sandy, well-drained, and slightly alkaline soils. Some regions in the Philippines have suitable soil, particularly in drier areas like Ilocos, Palawan, or Mindoro.
- Existing Global Plantations – Sandalwood is successfully grown outside India, including in Australia, Indonesia, and Sri Lanka, showing it can adapt to new environments.
Challenges & Solutions:
| Challenge | Solution |
|---|---|
| Long Growth Period (15–20 years for high-quality heartwood) | Requires long-term investment and patience. |
| Semi-Parasitic Nature (Needs a host plant to absorb nutrients) | Must plant with compatible host species (e.g., Acacia, Casuarina, or Albizia). |
| High Humidity and Rainfall (Can lead to fungal diseases) | Choose well-drained areas and manage spacing to improve airflow. |
| Illegal Harvesting Risks | Secure plantation areas and regulate harvesting practices. |
Best Growing Conditions:
- Soil: Well-drained, sandy, loamy, or lateritic soil; slightly alkaline (pH 6-7.5).
- Rainfall: 600–1600 mm per year; prefers moderate dry periods.
- Host Trees: Acacia, Casuarina, Albizia, Pongamia, Narra or other nitrogen-fixing trees.
- Spacing: 3m x 3m for optimal root connections with host plants.
In a nutshell:
Santalum album can be grown in the Philippines, especially in well-drained, moderately dry regions. However, it requires careful management due to its semi-parasitic nature and long growth period. If done correctly, a sandalwood plantation could be highly valuable, as demand for sandalwood oil and wood is strong worldwide.
