growing roses from seed
I would appreciate comments and suggestions on growing roses from seed. I have cross polinated two roses and now have hips that are maturing. I assume they will be ready for harvest later this summer or early this fall. Once I harvest the seed, what do I do next? How long can I keep the seed before planting? I don't have any greenhouse or growing area other than a window sill. Should I wait until late winter or early spring before planting?
