Q.Why Won’t My Pink Drift Rose Form Flowers?
I purchased a Pink Drift rose bush at a local nursery in January of 2022 and planted it that same day. It is located in full sun with well draining soil in a raised bed alongside several other roses. While it has grown significantly this year and produced many many buds, it has failed to produce very many flowers. The flowers that is has produced are deformed and discolored.
