Pre-treatment: Seeds are planted into round cell greenhouse flat liners with 38 cells per flat filled with coarse processed bark and composted pine bark growing medium. Seeds are 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. Prepared flats are lightly hand watered and cold stratified at 35 degrees Fahrenheit for a minimum of 21 days.
