Thank you, jerijem and Susan.. Sacramento's early frost date normally varies from the first week of Nov. to the first week of Dec., and the late frost date is usually in Feb., but can come as late as March 28. Last year, I think it only had one or two nights at 32 F. We have no hard frosts, and the temps any winter rarely get into the 20's, always being in Jan-Feb. Guess it must be significantly warmer in Pasadena, although with my own roses, I enjoy late Dec. blooms in my yard, sometimes being able to bring in a bouquet for Christmas. This question is being asked for the small public rose garden I volunteer at as I was offered help for early Nov. After I posted this, I sent an e-mail to one local master gardener with the question for confirmation pro or con, and they said it could be done, but not to put down fertilizer until Feb.
