I feed them and deadhead them, but they just get longer branches with fewer blooms.

Here is a fav knockout rose the sunny daze a yellow with a citrus scent
i manually pick off blooms regularly to promote more blooms, besides cutting them back once a year as the instructions say to do, fertilize them with knockout rose fertilizer, works best, water regularly and other than that knockouts are some of the easiest rose varieties to grow! Happy Daze to everyone!
