Toni, I read you right! I didn't think you knew what we meant.
Wintersowing starts on winter solstice (Dec 22). I use the method in summer too, with slight modification.
While gardeners have used some form of wintersowing since the beginning of time, it was Trudi Davidoff of Long Island who really made this wonder widely known on the internet around 10 years ago. She also pushed the method of using recycled containers like milk jugs. The wintersown.org site that ssgardener mentioned is Trudi's site. Definitely read it, then come back with questions and we'll be happy to help you. Don't miss the FAQ and Trudi's offer for free seeds. Yes, they're really free.

Nursery pots work, but best to cover them with clear plastic. It Works as a mini-greenhouse. In your climate (altitude) you'll need lots of vents to prevent overheating. And seedlings need head room to grow- keep the plastic up off the soil. They must be vented on top and have good drainage in the bottom. Use good potting mix, NOT SOIL. I highly recomment 3" of soil. Less will dry too fast. Poke more vents after they sprout, or remove the top. Recover for late frost
Best thing about wintersowing: no damp-off. While I do sterilize soil and containers for indoor sowing, I don't do any of that for wintersowing. My potting mix isn't sterile. And I don't even wash the milk jugs- I just rinse out the milk.
So see Trudi's site, and come back here with your questions. Many of us wintersow and we'll be happy to help you.
