Rose seed need a winters slumber outside, shallowly planted into a shallow pan. Cover the pan with a plank and let it sit outdoors, in the cold and wet.
As your spring nears take the plank off seed will germinate when temperatures warm.
I've tried this kind of cold-stratification in my fridge. it never ever works as well as a winters neglect outdoors.
Rose babies are about 1/4 the size of tomato babies of similar age.
The plank is to keep out visiting varmints, who most often want to hide their seeds in your pots. Make them do their own digging.
