I'm new to Winter sowing, so I'm not privvy to what types of seeds it's possible to winter sow, but I'll offer what I have, & someone can inform me if I shouldn't offer them here.

I know radishes & kale might do ok, but tomatoes maybe not.

I did have some tomato volunteers come up, from seeds over wintering in the soil, so maybe if tomatoes are tried, and some make it, we can naturally select for those.

I can send tomato seeds ONLY in a card, for one stamp, but if you want tomatoes AND other seeds, or non tomato seeds, the postage will be upgraded to a bubble envelope postage at $1.50.

I have many bubble envelopes here to reuse (save the cost of those), if you can just send stamps, or postage.

This is what I have......for (send stamps or paypal (no credit cards) postage~I have bubble envelopes & cards & envelopes here) or TRADE see my list)
