Why plant Knock Out® Double Rose?

Roses are a staple that every garden needs; beauty, fragrance, and splashes of color. Knock Out® Double Rose is all of that and so much more! Double Rose was bred to be a bit more disease-resistant and cold hardier than the rest, making it an award winner at the 2019 American Rose Trials for Sustainability! Though we can’t forget the main attraction here, those gorgeous fuchsia blooms! Aromatic and robust layered flowers will elevate you to a whole new level of gardening, and you don’t even need to have a green thumb to enjoy this kind of elegance! These roses are easy to please and might literally knock your socks off in beauty!

When the first Knock Out Rose hit the market in 2000, the Rose world was changed forever. At last, there was a Rose that stayed clean and healthy all season—and it bloomed for months! This marvel was bred by William Radler, a hobbyist who hybridized Roses at his Greenfield, Wisconsin, home and raised the seedlings in his basement.

How to use Knock Out® Double Rose in the landscape?

Rose blossoms are usually most vivid when the plants are grown in cool, mild climates. Knock Out is said to be an exception to the rule. In hot, humid climates, the flower color actually intensifies!

Hardiness Zone: 5-11

How To Plant Knock Out® Double Rose

Why are Knock Out® Roses so hardy? Well, they’re not only gorgeous, but they are also vigorous growers and cold hardy! They thrive in areas that receive full to partial sunlight, with about six hours of sun a day. A spot in your garden that offers afternoon shade over morning shade is preferred. Knock Out® Roses are adaptable to many different types of soil, as long as it is well-drained. They don’t like sitting in wet feet. Evenly moist soil, happy sunshine, and you’ll have a garden thriving in colorful roses!

How To Water

Newly planted Roses should be watered every two or three days, once Roses become established water them once or twice a week as needed to keep the soil moist.

How To Fertilize

Feed your Roses twice a year in March/April before flowering to encourage bigger and colorful blooms.

How To Prune

Prune your roses in very early spring once you see signs of new growth emerging. You can cut your rose back by one half to two thirds of the total size of your plant. Expect your rose to almost triple in size in the coming months.
