Saucer Magnolia (magnolia x soulangiana)


Question
How do you germinate these seeds (i.e. scarify? stratify? planting conditions: sun or dark, wet or dry, cold or warm?), do they have a high or low success rate and how long does the germination take?

Answer
HI Chris,
Thanx for your question.  For best results, cold-treat the seed for 60-90 days by placing the seeds in a damp paper towel and place inside a plastic baggie and seal it.  Place it inside of the refrigerator and leave it there for 60-90 days.  After that, plant the seeds 1/2 inch deep in a pot of good potting soil and keep it warm and moist, not, soggy.  Keep it under a 40-watt shop light and germination should begin about 3-4 weeks.  Germination can be erratic so give the seeds 3-6 months to finish germinating.  I don't have any figures on the germination rate.  I hope this helps.
Tom
