How to Grow Talisay Tree from Seed
The talisay tree, scientifically known as Terminalia catappa, is popularly called the tropical almond tree. It’s admired for its broad canopy, large glossy leaves that turn vibrant shades in autumn, and edible seeds that resemble almonds. Growing talisay from seed is a rewarding process, adaptable to various climates from the tropical shores of the Philippines to temperate corners of Canada and the United Kingdom.
Understanding Talisay Tree Seed Propagation
Seed propagation is one of the easiest ways to grow a talisay tree. The seeds have a hard outer shell, so germination sometimes requires a little prep work. Before planting your Terminalia catappa seeds, consider scarification—scratching or soaking the seeds to break dormancy and encourage faster sprouting.

Scarification and Seed Germination Tips for Talisay
- Soak seeds in warm water for 24 hours to soften the seed coat.
- Lightly sand the seed coat or nick it with a knife without damaging the seed inside.
- Plant seeds about 1 inch deep in well-draining, loamy soil enriched with organic compost.
In tropical regions like the Philippines and northern Australia, talisay seeds tend to germinate quickly due to warm temperatures and high humidity. In contrast, gardeners in temperate climates such as Canada or the UK need to start seeds indoors or in greenhouses to protect them from cold stress.
Best Soil and Climate Conditions for Growing Talisay Tree
Talisay thrives best in tropical and subtropical climates. It prefers sandy to loamy soil with good drainage—important for preventing root rot. While it is relatively drought-tolerant once mature, young seedlings require consistent watering to establish.
Regional Growing Tips
- Australia: In the tropical and subtropical zones, grow talisay outdoors. Use mulch to retain soil moisture during dry spells.
- Canada and United States: Start seeds indoors or in a greenhouse in USDA zones 10 and above. For colder areas, talisay can be grown as a container plant and moved indoors during winter.
- Philippines: Native conditions provide ideal humidity and temperature—simply sow seeds during the rainy season for optimal germination.
- New Zealand and United Kingdom: These temperate regions require indoor germination followed by transplantation into sheltered garden spots or large pots.

Caring for a Young Talisay Tree
Once your seedlings have sprouted, sunlight is crucial. Talisay trees prefer full sun but can tolerate partial shade in hotter regions. Regular watering is important during the first year, reducing frequency as the tree matures.
Fertilize young plants with organic compost or balanced slow-release fertilizer to encourage healthy growth. Given its tropical origin, the talisay tree appreciates soil rich in nutrients and organic matter.
Common Uses and Benefits of the Talisay Tree
- Edible seeds can be roasted and eaten.
- The leaves contain tannins used traditionally for medicinal purposes.
- The tree supports biodiversity by attracting birds and insects.
- Used in landscaping for coastal erosion control in places like Australia and the Philippines
