Our Knockout roses are blooming well; wondered if we trim off the dying roses or leave on the bush. Thank you

I trim them off because it looks better. Knock-Outs aren't known for producing colorful rose hips if any form at all. Removing spent blooms also gives me a chance to look over the bush for rose slugs, mites, Japanese beetles and other, less common, pests. But it is not mandatory and doesn't affect future bloom rate one way or the other.
