I have a standard patio rose in a container that has grown well and flowered for the last two years but will not flower this summer for some reason. I have other roses in and out of containers that are flowering well. I use the same multi-compost, multi-liquid feed, watering and rose pest control to kill off any bugs and black spot. This rose looks healthy, is growing well but is not budding or flowering at all. I also treated this rose to Bonemeal and Bayer Garden Toprose a few weeks ago hoping that would work but still no change. Do you have any other suggestions? Thanks. :)
