Here are 5 short tips for germinating Albizia saman (Rain Tree) seeds:
 
Scarify the Seeds: Use sandpaper or a knife to gently scarify the hard seed coat to help water penetrate and promote faster germination.
 
Soak in Warm Water: Soak the seeds in warm water (around 70-80°F / 21-27°C) for 24-48 hours before planting to soften the seed coat.
 
Warm, Humid Environment: Maintain a warm (75-85°F / 24-29°C) and humid environment, using a humidity dome or plastic wrap to keep moisture levels high.
 
Well-Draining Soil: Use a light, well-draining potting mix, such as a mix with sand or perlite, to prevent waterlogging.
 
Consistent Moisture: Keep the soil moist but not waterlogged.
Germination typically takes 1-3 weeks, so be patient and monitor moisture levels.
