Low Maintenance Plant: Knock Out Roses

Low Maintenance Plant: Knock Out Roses

Brighten your landscape with easy care high performing Knock Out® roses. 

These low maintenance plants will encourage you to add roses to your landscape even if you have struggled with rose maintenance and failures in the past. The Knock Out® family of roses has made it possible for all gardeners to add season long beauty to their shrub borders, flowerbeds and container gardens.

William Radler, breeder of Knock Out® roses wanted to introduce hardy roses that any gardener could grow and enjoy. The Knock Out® family of roses was his answer. The original member of this collection has cherry red/hot pink flowers throughout most of the season followed by orange-red rose hips that you and the birds can enjoy throughout the winter.

Double Knock Out® has more petals (double flower) that resembles a hybrid tea rose in appearance but with the same hardiness and low maintenance qualities of the original Knock Out®. Pink Knock Out® has bright pink flowers and Double Pink Knock Out® has the classic rose bloom in bubble gum pink.  Include Sunny Knock Out® for its fragrance, bright yellow flowers that fade to cream, and compact upright growth habit.

Knock Out® roses are hardy and resistant to black spot, powdery mildew and rust that plaque so many other roses. Plants may suffer minor infections in seasons when the weather is perfect for disease and stressful for the plants. Proper care will further insure your plants thrive and remain healthy.

Winter protection is optional on these hardy roses. Some gardeners choose to mulch the crown of the plant after the ground freezes. I prefer to leave the plants uncovered. Only twice in the fifteen years I’ve grown Knock Out® roses have mine died back to the ground. Simply prune off the dead stems and wait for new growth.

Minimal pruning is needed. Remove dead canes to the ground and winter damaged stem tips before growth begins in spring. Some gardeners prefer to prune the plants back to 12 to 18 inches for more controlled growth. And no need to deadhead as these plants will repeat bloom throughout the growing season.
