Caring for Knock Out Roses

When the original Knock Out® Rose was introduced by The Conard-Pyle Co./Star® Roses it was a revolution because of its vigor, disease-resistance, cold hardiness, and prolific bloom. Today there are 7 varieties in the Knock Out® Family of Roses – The Knock Out® Rose, The Double Knock Out® Rose, The Pink Knock Out® Rose, The Pink Double Knock Out® Rose, The Rainbow Knock Out® Rose, The Blushing Knock Out® Rose and The Sunny Knock Out® Rose.

All are cold tolerant to zone 5, heat tolerant throughout the U.S., reliably resistant to disease and produce a bevy of blooms every 5 to 6 weeks from spring until the first hard frost. I readily recommend these roses to my busy friends who need dependable no-fuss color in their landscape.

The natural inclination of The Knock Out® Family of Roses is to grow to about 3-4' wide x 3-4' tall, but they are easily maintained at a smaller size through pruning. They are ideal for growing in mixed borders, in containers or as a hedge.

Here are a few tips on planting and caring for Knock Out® Roses.

Just like other roses, The Knock Out® Family of Roses perform best when planted in full sun. The soil should be well drained and fertile.

Plant the roses 4 feet apart to allow for room to grow and good air circulation.

Space Knock Out Roses about 4 feet apart.

Give your roses consistent moisture. They need about 1 to 2 inches of water each week. Water deeply.

Give Knock Out Roses 1 to 2 inches of water per week.

To keep the flowers coming feed your roses with a fertilizer blended especially for roses. This should be done after each bloom cycle.

Feed your Knock Out Roses after each bloom cycle.

There is no need to remove faded flowers because these roses are self cleaning.

Prune in late winter or early spring, while the plant is still dormant. Remove any dead or damaged wood, do a little shaping if necessary, and take out some of the interior stems to improve air circulation.

Prune Knock Out Roses in late winter.

Every 2 or 3 years remove about one third of the old branches to stimulate new, fresh growth.

If you are trying to keep the roses at a certain height, you can cut them back hard with hedge shears. I've even seen Knock Out® Roses spring back beautifully after being cut down to 6-inches.

Knock Out Roses

I have just planted 2 of the Knock Out Roses. They are beautiful!! 2 people have called me at my place of business to ask what I have in front of my house. So far they have been very hardy and I understand I dont have to dead head them. This is an experiment for me as I have no knowledge of gardening. So wish me luck.
