Hard Seed Coat Scarification – File or gently crack the hard outer shell without damaging the inner kernel.
Soak in Warm Water – Place scarified seeds in warm water (25–30°C); change water daily.
Full Water Submersion – Keep seeds fully submerged; they are aquatic and germinate in water.
Warm Temperature – Maintain 25–30°C for best results.
Transplant to Pond/Container – Once sprouted, move seedlings to a container with heavy clay soil under shallow water.
Germination usually begins within 5–10 days after proper scarification
