The normal vegetative stage of agarwood seedlings (Aquilaria malaccensis) is the initial growth phase that spans from germination to the development of a young, healthy sapling ready for transplantation or field establishment. This stage typically lasts from germination up to 18–24 months, depending on environmental and management factors.
Stages of Vegetative Growth in Agarwood Seedlings:
| Stage | Description |
|---|---|
| 0–1 month (Germination) | Seeds sprout; cotyledons emerge; vulnerable to overwatering and pests. |
| 1–3 months (Seedling) | First true leaves appear; root and shoot systems develop; nursery care needed. |
| 3–6 months (Juvenile) | Stem begins to lignify; more leaf production; stronger root development. |
| 6–12 months (Early Vegetative) | Steady vertical growth; requires light pruning and root space. |
| 12–24 months (Late Vegetative) | Becomes transplant-ready; foliage thickens; trunk diameter increases. |
Key Growth Indicators in the Vegetative Stage:
- Leaf Growth: Broadening and increase in leaf numbers.
- Stem Thickening: Stronger central stem for future branching.
- Root Development: Taproot and lateral roots expand vigorously.
- No flowering or resin induction yet—pure energy goes into building structure.
Best Practices During the Vegetative Stage:
- Shaded Light (50–70%): Prevents sunburn and supports leaf development.
- Organic Fertilizer: Compost, vermicast, or fish amino acids monthly.
- Pest Management: Monitor for damping-off, aphids, and caterpillars.
- Watering: Keep soil moist but not waterlogged—essential for taproot health.
- Hardening Phase (18–24 months): Gradual exposure to sun before field planting.
