Germination Information
Pre-treatment: Seed is planted into round cell greenhouse flat liners with 38 cells per flat that have been filled with coarse processed bark and composted pine bark growing medium. Seed is surface sown at a rate of 3-5 seeds per cell and lightly covered with starter sized, 1/16" - 1/8" diameter, granite poultry grit to combat damping off diseases. Prepared flats are lightly hand watered to slightly moisten the growing medium.
Establishment: Seed collection is very time-consuming and quality of seed is questionable. Seed ripening is uneven and seed shatters readily at maturity. No pre-treatment is used in the second protocol.
