Bloom on roses
I usually have a good first bloom on my roses, but after that it is just here and there. Yes, I fertilize monthly. Do I cut them incorrectly perhaps?
Feeding the rosebushes with a fertilizer with too high an nitrogen content can cause this. I recommend feeding the roses with a good even NPK ratio organic rose food and water them well. Feeding monthly should not be necessary. Here are some links to articles that should be helpful to you: https://www.gardeningknowhow.com/ornamental/flowers/roses/rose-fertilizer.htm
