How to Plant Double Knock Out Rose® Red

Choose the Right Spot

Double Knock Out Rose® Red thrives in full sun, ideally receiving 6-8 hours of direct sunlight daily. This sunlight is essential for optimal blooming. However, they can tolerate some afternoon shade in hotter climates. While adaptable to most soil types, Double Knock Out Rose® Red prefers well-drained soil. If your native soil is heavy clay, amending it with compost or other organic matter before planting will improve drainage.

Measure the Space

Double Knock Out Rose® Red bushes mature to a height and width of 3-4 feet. This compact size makes them ideal for planting in garden beds, borders, or even containers. When planting multiples in a row, space them 4 feet apart to allow for proper air circulation and room for growth.

Dig the Hole

Dig a hole that’s twice the width of the root ball of your Double Knock Out Rose® Red and just as deep. Loosening the soil at the bottom of the hole encourages healthy root development.

Plant It

Gently remove your Double Knock Out Rose® Red from its container and loosen any circling roots. Position the plant in the hole so the crown (where the roots meet the stem) sits at ground level. Backfill the hole with soil, tamping it down gently to eliminate air pockets and secure the plant.

Water Thoroughly

Give your newly planted Double Knock Out Rose® Red a deep watering to settle the soil around the roots. Aim to soak the soil thoroughly, allowing any excess water to drain away.

Mulch and Care

Apply a 2-3 inch layer of mulch, like shredded bark or wood chips, around the base of the plant to retain moisture, regulate soil temperature, and suppress weeds. Keep mulch a few inches away from the stem to prevent rot. Established Double Knock Out Rose® Red are surprisingly drought tolerant. Water deeply during dry periods, allowing the soil to dry slightly between waterings.

Watering

Established Double Knock Out Rose®s are surprisingly drought tolerant. Water deeply during dry periods, allowing the soil to dry slightly between waterings.

Sunlight

These roses thrive in full sun (6-8 hours daily) for optimal blooming. They can tolerate some afternoon shade in hot climates.

Fertilizing

Feed your rose in early spring with a balanced rose fertilizer to encourage healthy growth and abundant blooms.

Mulching

Replenish mulch around the base of the plant each spring with a 2-3 inch layer to retain moisture, suppress weeds, and regulate soil temperature.

Pruning

Prune lightly in late winter or early spring to remove dead or diseased canes, and to shape the bush as desired.

Disease and Pest Management

Double Knock Out Rose®s are disease resistant, but keep an eye out for common pests like aphids or mites. Treat organically if possible, using insecticidal soap or neem oil.

Winter Care

In colder climates, apply a layer of mulch around the base of the plant in late fall to protect the roots from freezing temperatures.

When It Arrives

Give your newly delivered Double Knock Out Rose® a thorough soaking before planting. Let the water drain freely to avoid waterlogged roots.

During The First Year

Water your rosebush deeply once a week, allowing the soil to dry slightly between waterings. More frequent watering may be needed during hot, dry spells.

After The First Year

Established Double Knock Out Rose®s are drought tolerant. Water deeply during extended dry periods, but allow the soil to dry completely between waterings.

Extra Tips

Water early in the morning to allow the plant to absorb moisture before the heat of the day. Focus watering on the soil around the base of the plant, avoiding the leaves and flowers to prevent fungal diseases. Observe your rose - wilting leaves are a sign it needs water.

When It Arrives

No need to fertilize your new Double Knock Out Rose® when it arrives. The existing potting mix should provide sufficient nutrients to get it established.

During The First Year

Wait until spring of the first year before fertilizing. Apply a balanced, slow-release fertilizer formulated for roses according to the product’s instructions.

After The First Year

Continue to fertilize once a year in early spring with a balanced, slow-release rose fertilizer. This will provide sustained nourishment throughout the blooming season.

Extra Tips

Avoid over-fertilizing, as this can lead to weak growth and less flower production. If you see pale foliage, you can give your rose a light feeding with a water-soluble rose fertilizer during the summer months, but be sure to follow the product’s recommended dilution rate.

What Tools You’ll Need

Sharp bypass pruners or loppers will do the trick. Make sure they’re clean and well-maintained for smooth cuts.

Pruning Steps

In late winter or early spring, before new growth emerges, prune to encourage bushier growth and abundant blooms. Remove dead, diseased, or weak canes. Shorten healthy canes by one-third to half their length, making angled cuts just above an outward-facing bud.

After Pruning Care

Apply a sealant (optional) to larger pruning cuts to help prevent disease. Water your rosebush thoroughly after pruning to encourage new growth.

Extra Tips

For a more compact bush, prune more heavily. For a taller, more open bush, prune less severely. You can also deadhead spent blooms throughout the season to encourage continuous flowering. Remember, Double Knock Out Rose®s are forgiving when it comes to pruning, so don’t be afraid to shape them as desired.
