I live in Clearwater Fl...west coast of Florida and am concerned about some salt spray from the Intracoastal waterway.
Are Knock Out Roses Salt Tolerant?
No roses really handle salt well. The Knock Out and Home Run lines of rosebushes are very hardy rosebushes and will handle the conditions better than most other varieties. I would recommend planting a couple of either line of rosebushes and see how they do, plant them in an area that is the most protected from the spray as possible.
