Thanks Dave and Carleen for your input on how to stratify seed. I soaked my refrigerated R. Carnina seed overnight and planted them this past weekend. Got my fingers and toes crossed!!! ;-).
Does anyone know the germination times for rose seed? I planted them in a soiless mixture and put them outside in a bright place with plastic wrap over the top of the pot. I was wondering if bottom heat would help them germinate faster.
Carleen, were you able to find a source for "sweetbrier" - r. eglanteria seed? I don't think Richter's had those.
