About Your Petite Knock Out® Rose Bushes

When rosarian William Radler was a teenager, he resolved to breed a hardy rose that was beautiful, bloomed all season, was disease resistant, and maintained an attractive shrub-like habit. He remains committed to breeding the "high-maintenance" issues out of his roses. He succeeded with his first introduction, Knock Out™, the award-winning shrub rose that mail-order catalogs call "perhaps the best-ever landscape rose for four-season interest." Mr. Radler germinated the first Knock Out seed in his basement during the winter of 1988–89, and that spring he planted the small shrub outside in his garden. The following 11 years were spent overseeing bud grafting, testing, and production of more stock. The rose was offered to the All America Rose Selections committee and declared a winner in 1997. Knock Out became available to the public with 250,000 plants in production. And a star was born. In 1992 a well known company known as Star Roses & Plants near Philadelphia signed a contract with Radler to begin testing on his new rose, a process which took eight years. With testing complete, the company filed for a patent and named the new, easy-care rose Knockout. Sales began in the year 2000. The Petite Knock Out Rose Bush is a brand new addition to the Knockout collection!

Planting Information

Before you buy a Petite Knock Out Rose, make sure to read about the care instructions that are required and recommended to keep this plant healthy and thriving.
How do I mulch Petite Knock Out® Rose Shrubs?

How do I mulch Petite Knock Out® Rose Shrubs?

We highly recommend that you mulch your Petite Knock Out Rose shrub with either a ground hardwood mulch or a ground cypress mulch depending on your local availability. Any type of mulch will do but cypress or hardwood mulch will be of a higher quality and provide better nutrition overall as they breakdown. Mulching helps to keep weeds away which will compete with your new investment for water and nutrients. A 2 to 3 inch layer of mulch is sufficient but remember to take care not to cover any part of the stem of the plant with mulch. It's better to leave a one inch gap of space between the mulch and the stem or trunk of the plant.

How do I fertilize Petite Knock Out® Rose Bushes?

How do I fertilize Petite Knock Out® Rose Bushes?

Shrub roses such as Petite Knock Out Roses grow best if they are fertilized once or twice in the summer. You should fertilize your roses monthly from springtime to fall. Knock Out Roses like nutrient rich soil and ample fertilization. Try using some Epson salt as well. This will help boost the levels of magnesium in the soil which promotes increased flower production. When selecting a fertilizer for your Knock Outs, use a rose fertilizer blended specifically for roses such as Espoma Rose Tone for example. Either chemical fertilizers or organic matter can be used successfully.

How do I water Petite Knock Out® Roses?

How do I water Petite Knock Out® Roses?

After back filling and lightly compacting the 50/50 mix of existing soil and compost give the Petite Knock Out Rose a good deep watering. This is not to be rushed. Most of the water you put on the plant at first will run away from the plant until the soil is soaked. A general rule of thumb is to count to 5 for every one gallon of pot size. For example a one gallon pot would be watered until you count to 5 a three gallon pot would be 15 and so on. Check the plant daily for the first week or so and then every other day there after. Water using the counting method for the first few weeks. You’ll want to water the bushes regularly after planting until they’ve been well established. We like to tell folks that when watering Roses its best not to water the foliage of the plant. Water at the base of the plant near the soil line only. Although Knock Out roses are generally resistant to black spot there are other foliage diseases that can effect roses in general that are favored by wet foliage conditions. Gator bag Jr. can be used to help aid in this process and also provide plants with a good soaking due to the slow release of the water into the root-zone of the plant. Soaker Hoses can also be used to water when planting a long hedge.

How do I prune Petite Knock Out® Roses?

How do I prune Petite Knock Out® Roses?

It is best to prune your roses during the late winter or early spring. You can remove dead leaves and prune to shape but deadheading is not necessary as it is a self cleaning rose shrub.
