red knockout roses are blooming pink

Question

I planted red knockout roses, so why are they blooming pink? Live in Lake Charles, La. (70605), one hour away from the Gulf of Mexico. My neighborhood is 20 years old and once was rice fields.

Answer 1

It could be that the roses are lacking in some nutrient that is causing the change in color. Having the soils tested is the only wall to really know. If the roses were older it could be that they created what is called sport rosebushes, which is how pink knockout came to be.
