How to germinate Magnolia sieboldii seeds:

Stratifying seed. Never let magnolia seed dry out as this kills the embryo. Sow immediately 2 cm deep, keep moist, keep the pot outside to finish the cold stratification cycle of 120 days. Sunlight inhibits germination. Most seed will germinate in May with the remaining the following year. Newly emerging seedlings need indirect light/dappled shade at first then stronger light as they put down a larger root system. Protect from nibbling pests two years. If you baggie sow these provide room temps with no supplemental warmth as they don’t seem to tolerate this. Once you see them crack open, transplant into a pot 15 mm deep as they don’t like being in the bag when root is more than 2cm long and mortality can be high.
