Step-by-Step Sandalwood Seed Germination Guide.
1. Seed Preparation
- Sandalwood seeds have a hard shell; soaking them in a natural cow dung slurry for 12 hours improves germination success.
- Alternatively, soak seeds in gibberellic acid solution mixed with sodium hydroxide to speed Germination (especially for commercial planting).
- Lightly nicking the seed coat with a blade can help water absorption.
2. Soil and Bed Preparation
- Use well-drained sandy soil or a mix of sand and fertile soil (1:1 ratio).
- Raised or sunken seed beds (about 10m x 1m) are ideal.
- Maintain good moisture and high humidity but avoid waterlogging.
3. Sowing Seeds
- Plant seeds 1.5 cm deep in prepared beds or pots.
- Cover seeds lightly with soil or sand.
- Water gently, using a fine mist spray to keep soil moist.
- Keep the sowing area shaded from direct sunlight.
4. Germination Conditions
- Seeds typically germinate within 21 to 60 days.
- Maintain temperatures between 25–40°C with high humidity.
- Cover seed beds partially with straw or fiber bags to retain moisture.
- Mist regularly.
5. Early Growth and Care
- Sandalwood is a hemi-root parasite requiring host plants like red gram, drumstick, or pigeon pea nearby.
- After 2 months, seedlings become strong enough for transplanting into polybags with nutrient soil.
- Harden the seedlings by gradually exposing them to sunlight before field planting.
