I have seeds that generally need to be stratified (cold) before planting them. (Plum, apricot, cherry, peach).
I didn't really care too much if they germinate, I just threw them in the soil as an experiment.
I did this over the last few weeks (I'm in Australia so it is summer at the moment). Will my seeds stratify over the winter then sprout in the spring? Or will it fail due to how early I planted it?
