Planted a dozen "Red Freedom" hedge roses bought bareroot from Springhill the first spring after I moved in, they grew to 4ft and bloomed from June through November till a killing frost. The second year they were 6ft monsters with some canes an inch or more across. I pruned heavy the following spring and they still got huge. I put Meidilands around my birdbath and Knockouts along the driveway. All bloom now from May till killing frost and some even a bit beyond if we have an Indian summer.
Black spot and Aphids are the devil though. Don't water the leaves in fact I don't water them at all if we get biweekly or so rain and they do fine. Spraying with a solution of dish detergent and baking soda seems to help with both Aphids and Black Spot.
Black spot is the yucks! That's why I want to convert all my flower beds to drip.
