Imagine a garden bursting with color all season long, with hardly any effort on your part. The Double Knock Out Rose® Red can turn that dream into reality. This disease-resistant shrub continuously produces vibrant red, double blooms from spring right up until the first frost. You won’t have to fuss with constant spraying or worry about common rose ailments – this low-maintenance beauty thrives with minimal care, leaving you more time to enjoy its stunning fragrance and cheerful presence in your outdoor space.
The velvety petals unfurl with a soft, luxurious texture, like cool satin against your fingertips. As spring unfolds, the blooms emerge in all their pristine glory, boasting a perfect, double form. Throughout the summer, the roses maintain their vibrancy, the red color showcasing a hint of warmth under the sun’s kiss. And the best part? This isn’t a fleeting display.
The Double Knock Out Rose® Red is a tireless bloomer, continuously producing these stunning flowers throughout the season. Even as fall approaches, the blooms hold their own, the red color deepening slightly, like a jewel reflecting the autumnal light. So imagine yourself surrounded by these blooms, their rich color and soft texture a constant source of beauty and delight in your garden.
The Double Knock Out Rose® Red isn’t just about the blooms. This vibrant shrub boasts attractive foliage that complements the flowers beautifully and adds textural interest throughout the seasons. Picture a blanket of deep, olive green leaves emerging in spring, their surface smooth and cool to the touch. As the sun warms things up, the foliage takes on a richer, more lustrous sheen, adding depth to your garden borders.
Unlike many flowering shrubs, the Double Knock Out Rose® Red doesn’t sacrifice foliage health for flower power. The leaves maintain their rich color and stay free of blemishes well into fall. As the season progresses, the foliage might take on subtle hints of burgundy or bronze, adding a touch of warmth to your garden’s color palette. Even after the blooms fade, the lush green foliage continues to provide visual interest until the first frost arrives.
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.
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 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.
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.
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.
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.
It’s a gateway to a more beautiful, serene outdoor space. With its disease resistance and low-maintenance requirements, the Double Knock Out Rose® Red lets you enjoy these benefits without the hassle. No more battling pests or spending hours on complicated care routines.
This easy-to-grow shrub thrives with minimal effort, rewarding you with a season-long display of color that will be the envy of the neighborhood. Invest in a touch of paradise for your own backyard - buy your Double Knock Out Rose® Red today and watch your garden transform into a vibrant escape.
Established Double Knock Out Rose®s are surprisingly drought tolerant. Water deeply during dry periods, allowing the soil to dry slightly between waterings.
These roses thrive in full sun (6-8 hours daily) for optimal blooming. They can tolerate some afternoon shade in hot climates.
Feed your rose in early spring with a balanced rose fertilizer to encourage healthy growth and abundant blooms.
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.
Prune lightly in late winter or early spring to remove dead or diseased canes, and to shape the bush as desired.
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.
In colder climates, apply a layer of mulch around the base of the plant in late fall to protect the roots from freezing temperatures.
Give your newly delivered Double Knock Out Rose® a thorough soaking before planting. Let the water drain freely to avoid waterlogged roots.
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.
Established Double Knock Out Rose®s are drought tolerant. Water deeply during extended dry periods, but allow the soil to dry completely between waterings.
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.
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.
Wait until spring of the first year before fertilizing. Apply a balanced, slow-release fertilizer formulated for roses according to the product’s instructions.
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.
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.
Sharp bypass pruners or loppers will do the trick. Make sure they’re clean and well-maintained for smooth cuts.
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.
Apply a sealant (optional) to larger pruning cuts to help prevent disease. Water your rosebush thoroughly after pruning to encourage new growth.
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.
