HI I have a few rose seed planted. My question is what is the optimum temp. for rose germination?
Not sure of the optimum temp, but I can get seeds to germinate in the fridge, and I remember reading somewhere (Hybridizers Handbook?) that temps over 70F inhibit germination.
Larry, did you chill the seeds before planting them? Most seeds need to be chilled for some weeks before they’ll germinate.
JIM… I did stratify the seeds for several weeks.I have three seedlings up now… two are Gene Borner x Love The other one is Diana Princess of Whales
