I'm excited to start winter sowing again. I missed it last winter due to health issues. In my area (central Minnesota) it can still inch up to or above freezing in January, but we have our coldest week in February. Winter sowing months are generally February, March, April, and into May for seeds that don't need stratification.
This year I want to try again with apple seeds. I don't plan to plant the seedlings as part of the orchard, but instead plant them randomly around the further areas of the homestead. Then they'll have to fend for themselves. If they grow, excellent! In a few years we might find some apple surprises. If not, then it wasn't a huge waste of time or space to try. Those that survive are sure to be hardy varieties, and those that produce inedible fruits can always be cut down and the wood used for animal chews or smoking meats or something. No waste.
I suppose there will be lots of tomatoes and peppers and other varieties winter sown too. I'll have to pick what I'm growing this year. I should really focus more of my attention on researching the varieties already in my collection than adding more to it.
