Plant them 2 - 3 feet apart in a zig-zagging planting pattern. Mulch between plants and keep them weeded as they fill in.

Plant them in the ground or use them in colorful containers. Use one or use several in a long drift or mass planting for a huge boost of curb appeal.

Knock Outs® is a forgiving plant that works well with many styles.

#ProPlantTips for Care:

Give these Knock Out® Roses a full sun location in soil that drains well. Water enough to maintain consistent soil moisture at first, but once established, Knock Out® Roses are quite self-reliant except during extreme conditions. Feed a good organic fertilizer in early spring, and again in mid-summer. Mulch your plants to 3 to 4 inches deep and spread out 3 feet. This will keep roots cool and maintain surface moisture. This will also help in controlling weeds and provides a nice, uniform look to the garden bed.

You may not need to prune every year, but can easily keep them clipped back by removing the top third of the length of the branches in late winter. Head them back and make your pruning cut right above a swelling bud. Find more info about pruning Roses, winterizing Roses, and un-wintering Roses in spring.

You can also remove the thickest, oldest stems all the way down to the ground. This will rejuvenate your Rainbow! These top performers are a go-to selection for hard-working families. You'll love the smaller size. Like all Knock Outs®, these are bred for toughness and disease resistance. They won't give you any trouble in the landscape.

  • Best in Full Sun
  • Moderate Moisture Needs
  • Enriched Well-Drained Soil
  • Disease Resistant to Black Spot
  • Cold Hardy & Heat Tolerant

Rose Bush FAQs

Where Is The Best Place To Plant Rose Bushes?

Roses need a protected location and prefer full sun and favor the drying power of the morning sun and flower best in at least 6 hours of direct sunlight a day. Choose a location in good, enriched soil that drains well and has good air circulation.

What Is The Best Month to Plant Roses?

You can plant Roses any time if you are able to provide enough consistent moisture and attention. While there is not a specific month that is best, generally because it changes with temperatures, climate and growing zone. However, the easiest times of the year to get Rose bushes established in your landscape are in spring after the last frost date, and in fall about 4-6 weeks before the first frost.

Do Roses Come Back Every Year?

Rose bushes are deciduous woody perennial shrubs and will return bigger and better each year.
