Harvest the cones as they start to turn brown and open, likely in October. Dry the cones so they open out, and shake the seeds out.

Put the seeds in some sterilised damp (not dripping wet!) sand, and refrigerate at +1 or +2°C over the winter.

In spring, sow in pots indoors (early spring) or outdoors (when risk of frost is over). Use a well-drained peat-free soil mix. Keep moist, but not wet.

Thanks for the information Resin!

If I am successful I will cronicle the process and share the results.

the sylvestrus in my yard... grow the cones this year ...

and after winter.. on the first 70 degree moment.. you can hear them clicking open ....

then the seeds fall to the sand.. covered with pine needles..

and i have hundreds of volunteers one inch big all summer.. or until i spray them with round up ...

how is that on perspective of what you want to accomplish ...

winter can be replaced by a fridge ...

then you are left with potting media or soil ... etc
