We have! It does work! I’ve been meaning to write an article about it, we’re finally taking pictures this year for it! The gist is that the seeds will come up when the conditions warrant. The “gotcha” with winter sowing, and why we don’t practice it in general, is that it really only works for fairly cold hardy plants. (e.g. cabbage, broccoli, kale, other brassicas, etc) You could not, for example, expect to grow tomatoes or peppers well that way, given the likely frost, temperature risks and extremely low germination temperatures. Also wouldn’t work for crops/flowers that require sowing more than 6-8 weeks before last frost. So, lots of limitations that don’t work for us, but would absolutely work for some people! We should have our in-depth article ready next season where we’ll cover ALL the details, but hopefully the above gives you the “key” guidance for this season.

Also, this spring is whack, meaning there’s a seasonal component too. We’d suggest waiting until temperatures are reliably above 20 degrees before putting them outside!
