I saved a bunch of plasic food containers and poked holes in the top, filled with dirt and planted seeds of every kind. Usually, I stink with plants so it was a nice surprise to raise so many ‘super seedlings’ that year. Apparently, the repeated freezing/thawing made the seeds strong. Who knew???
Does that work with seeds like tomatoes, too?
I’ve had tomato plants come up in the spring spontaneously.
I would imagine that it would work with any annual but I never really thought about it but if it can grow stronger plants, then it’s worth a try.
I’ve had a lot of weak seedlings the last few years and would like to avoid that.
There used to be a web site: Wintersown which had instructions for using Milk jugs. They also had free seeds or nominal donations, but I don’t think they are around any more.
