Why Are My Knockout Roses So Bad?

Question

I bought this pot of knockout roses last year and planted it in my front yard. I am getting a very good number of flowers. However, the roses have always been blooming like in the pictures, the petals are wide apart and are not held together. The plant itself seemed to like the soil and location as it grew twice in size with many leaves and new stems. I am quite new to gardening and would appreciate any help to fix the plant. The plant food I use commonly for all my flowers is 10-52-10.

This is common for single Knockouts. Doubles Knockouts are much more full, and what most people think of when they think of Knockout Roses.

I do notice what may be a bacterial issue popping up. Make sure to allow the soil to dry out a little between waterings. It is essential for the first few inches of soil to fluctuate between wet and dry to keep the beneficial microbes around, while keeping harmful bacteria away.
