What type of maintenance is required for knock-out rose bushes, if any?

Answer 1

Knock-out rose bushes require constant attention. Once a week you should check for aphids and spray with a mild dish-soap/water solution (1 teaspoon dish-soap to 1 quart of water in a sprayer) as a preventative. If you pick the flowers to show or put in vases, then trim properly. If you don't, you should trim dead roses off to encourage branching and faster propogation next year. At the end of the season (Mid-fall), throw dead leaves and coffee grounds around the base as a mulch. Caution! If it is an early blooming rose then follow the above procedure. If it is a late blooming rose (mid-summer), then trim back every major branch down to about 12 inches long (IN THE FALL) and enjoy the show in late summer next year.

Roses are very heavy feeders so it is best to feed your rose to encourage growth and maximum bloom. I fertilize with a root drench of Kelp/Fish on May 1, June 1 and July 1. I use Growmore seaweed extract and Alaska® Fish Fertilizer 5-1-1 to make this.

I fertilize three times a year Valentine's Day, Memorial Day & Labor Day, in zone 7, using Whitney Farms Rose & Flower 4-6-2.
I also use the Kelp/Fish blend as a foliar spray to reduce disease. I have over fifty roses and I treat then all the same so a few do show some black spot (BS) later in the year with out fungicides. However the Knockout rose never shows any BS.

Mulch keeps the soil cool and moist as well as breaking down to feen the rose over time. I like to use a fertile mulch (wood chips ground with manure).

I've never had more than a few aphids on any rose. All I do is use Safer soap spray.

Repeat-flowering shrub roses bear flowers on mature stems that are not old and woody. Severe pruning of these roses would result in reduced flower production. In their first two or three seasons in the garden, shrub roses can be left unpruned. Then you can, In the spring, remove one-third of the very oldest canes if the shrub needs care.

Answer 3

Hardly any maintenance is required. Just trim off the withered blossoms if you want - but the bush will continue to bloom lavishly even if you don't. Knockout roses are fabulous, disease-free, and easy to care for.

Answer 4

Knockout roses don't require as much maintnance of other varieties, but still need some care.. They need to have a mild shade area. I would also recomend rose food.
