What NPK Ratio Do Roses Need?
Roses need a balanced to phosphorus-rich NPK ratio like 4-6-4 or 5-10-5 to promote blooming. During spring growth, a balanced 10-10-10 works well. Switch to higher phosphorus during bloom season. Avoid very high nitrogen ratios which produce leaves at the expense of flowers. Dedicated rose fertilizers like Espoma Rose-tone (4-3-4) are formulated for optimal rose nutrition.
