Be sure to see a few short videos about planting and caring for Knockout Roses at the bottom of this page! (not viewable in Quickview).
Knockout Roses need 6-8 hours of full sun every day.
The more sun there is, the more they will thrive and produce flowers.
Knockout Roses will perform beautifully, even without fertilizing.
If you choose to give them an additional boost, it is very important not to fertilize until after the roses are established and go through one bloom cycle.
Use a balanced fertilizer or fertilizer formulated for roses and apply after the first wave of flowering.
Make sure the soil is moist before you fertilize to avoid burning the roots.
Do not fertilize late in the summer, as this is the time the rose should be preparing themselves for dormancy, and you do not want to create additional unnecessary new growth that will likely die back from the first hard frost.
Knock Out Roses should be cut back once a year to 12” high.
Check your rose bush from time to time in late winter/early spring, and when you start to see new shoots growing from the canes on your rose bush, that's a good sign that it's time to prune.
Knockouts are self-cleaning, so no need to deadhead.
If you want to keep it blooming continuously, you need to groom it.
This means clipping off the faded flowers.
If you leave them, they'll form rose hips with seeds inside, and flowering will slow to a crawl.
Grooming every week or so spurs new growth loaded with new rose buds.
