Simplified Seed Starting

Step 1: Collect Ripe Seeds

Gather seeds after pods naturally dry and split on the tree (late summer/early fall).

Step 2: Prepare Seeds

Open ripe pods, extract seeds. Nick seed coat with a file to speed germination.

Step 3: Soak Seeds

Submerge seeds in warm water for ~1 hour.

Step 4: Plant in Containers

Fill 4-inch pots with light, well-draining potting mix. Firm lightly. Make 1-inch center indentation, place seed, cover, firm gently.

Step 5: Water and Maintain

Water until drainage occurs. Keep moist until germination (3-4 weeks). Then water 2-3 times weekly (weather-dependent). Maintain lightly moist, not soggy.

Step 6: Provide Light

Place in area receiving 4+ hours daily direct sunlight for germination.
