We're overdue reporting on the results of this winter-sowing project from mid-February.
Fact is, our hearty winter-sown mustard, tatsoi, and arugula seeds have been leafing out for a couple weeks, though we're taking our time planting them. The tiny, well-rooted plants are easy to pull up and tuck into many a spot.
We'll definitely be winter-sowing again next year. I'm very glad to have learned about this from fellow GRG-er Debbie.
