How to germinate Magnolia obovata seed:

Stratified seed. No longer needs cold stratification. Best to sow immediately upon arrival.  Prepare a deep pot with warm moisture retentive well draining medium. Sow 1cm deep sinking the seed edge side down. Give a thin layer of fine mulch.  Best if pot is fitted with a clear plastic bag to retain moisture, warmth, and keep pests (slugs love eating magnolia seedlings).  Place somewhere warm to encourage uninterrupted germination for big healthy seedlings.  We communal sow our magnolia spacing 3 cm apart as in the pic to conserve space under grow lights and greenhouse.  There really is no advantage sowing each seed in its own 1 gallon pot.
