I’m trying Bonsai again. Got Norway Spruce (Picea Abies) seeds.
Timeline Summary and Action Tracker (Newest to Oldest):
20230527 – Soaked a paper towel and placed in zip-loc bag and placed 6 seeds on top; put in fridge; wait 3 weeks
20230527 – Discarded seeds that remained floating on top. 6 Seeds to now work with.
20230526 – Soak seeds in lukewarm water and wait 24 hours
Steps for Cold Stratification:
Soak the seeds in a container of water for 24 hours.
Seeds that sink to the bottom are the ripest, whereas floating seeds are usually empty shells that will not germinate.
Remove these seeds.
Place the good seeds on a damp paper towel.
Seal the paper towel and seeds into a clear plastic bag.
Place the bag in the refrigerator for 7 days to cold stratify.
Remove the seeds from the fridge and plant.
