Stratifying cold frame

I was asked how I stratify so many different varieties of seed every year, still around 200-300, although until recently it was over 400. I then had two of the cold frames shown in the video. It’s just a wooden frame with Enviromesh draped over to stop mainly birch seeds from entering but allowing water to pass through. You will also see the various mostly recycled sow pots that I use, including milk cartons on their side with holes punched in the bottom for drainage (stapled at the ends). I sow up to 10 different species in each milk carton tray, not sowing plants from the same family close to each other in case the seed wanders! Hope this helps :)
