propagating seeds from a Dawn Redwood


Question
I have been collecting seeds from a Dawn Redwood.
What is the best process to use to successfully germinate the seeds?  

Answer
Hi Steven,
Thanx for your question.  I apologize for replying late due to the holidays and some technical difficulties.

Most tree seeds can easily be germinated by planting them in a pot of potting soil as deep as they are long and cover with soil.  Place outside all winter long.  Most tree seeds need at least 90 days of a cold period under 40 degrees F to break the dormancy.  They should sprout in the spring after the last frost.  Some seeds may require several cold periods to germinate.  If you want to speed it up, plant the seed as directed above and place inside a plastic baggie and place inside the fridge for 90 days.  Then take out of the fridge and expose to consistent temps of 70-75 degrees F for 60 days.  If no germination, repeat the fridge process and then back out to warmth.  I hope this helps.
Tom
