Product Description

This Red Double Knock Out® Rose bush will be a knock out of the park with its explosion of color all summer long!

The double red knockout rose bush has set a new standard in disease resistance when it comes to a beautifully bright and low maintenance bloom. It is of the same rose family of the original rose of the knock out family from Star Roses and plants.

This rose plant produces rich, cherry red to hot pink blossoms that will continue to grow until the first hard frost of winter. The bloom cycle starts in early spring. Roses will bloom from spring until mid summer before the weather gets too hot. They are full double flowers on a shrub rose bush..

The red roses contrasts nicely to the dark green foliage of the flowering shrub. If grown as a flowering tree, the blooms will cascade over the green leaves year after year. This classic rose is slightly more winter hardy than other roses.

The rose bush features incredible resistance to black spots and powdery mildew leaf diseases, and is an excellent choice as a low hedge or accent plant in mixed beds. They can even be container grown as an indoor patio plant.

Knockout Rose Care

Grow the Red Knock Out rose tree in full sun to partial sun across the United States in USDA hardiness zones 5-10. It can get up to 3 feet tall and wide and is extremely fast growing. The best time to plant the knockout roses is in early spring or fall so it has a whole growing season to establish its root system.

Double knockout rose bushes prefer well drained soil. A slow release fertilizer at the top of the root ball will help tremendously with new blooms.

They are extremely cold hardy and easy to grow roses. They can be grown in most areas of the country and the red flowers will grace any landscape. Drought tolerant and self-cleaning, this aesthetic rose shrub suits every garden and every lifestyle.

Double Red knockout roses are easy to care for and provide beautiful rose blooms during the spring and summer blooming season.

Perfect Plants offer their very own specially formulated Rose Planting Mix to amend the soil you are planting your new rose bush or rose container in.

Shipping Info

Once your Double Red Knock Out® Rose order is placed, we will ship your plant(s) within seven business days year round unless during the checkout process you request otherwise in the space provided to do so.

Perfect Plants’ shipping specialists carefully package your plants using a proven packaging method that ensures your plants arrive healthy, colorfully alive and ready to flourish. We’ve coined the term ‘upside down box test’ and we do just that; we carefully package so that regardless of the direction your box is handled, it will not harm your precious plant that’s inside.

No shipping process is without a problem from time to time. On rare occasions some plants may experience some of the following during their transit: drooping, minor leaf-loss and/or minimal yellowing/discoloration, minor limb damage, etc. These instances are quite rare, but can happen when shipping plants in boxes.

Plants normally recover within a few weeks after planting. If a damaged box has injured your plant on the inside, please notify us within 5 days of receiving you package(s) by emailing us a photograph of the damage.

We always do our very best to ensure that your plants are packed and shipped in the safest, gentlest and most effective way possible.

Will my plants and trees look like the photographs?

Absolutely! Unlike other online nurseries, our photos are of actual plants and trees we’ve grown here, on our family operated nursery.

Growing our own plants and trees helps to ensure we ship you the best quality plants that are free of pests and diseases.

Your plants and trees may however not ship with flowers on them, like the photographs. This all depends on the time of year you buy your plant or tree. Crape Myrtle trees, for example, only bloom during the summer months, so if you purchase one during the spring or fall, they would ship without flowers. Once planted, your plants will grow and thrive giving you flowers for many years to come!

Pot Sizes

Pot sizes (commonly referred to in gallons) are shipped in the same size nursery trade pots which may vary in actual volume. Some plants may have been at the approximate pot size listed, but require excess dirt to be removed so that you will not be paying any additional shipping costs. This doesn’t happen very often though.

Shipping Fees

Our shipping charges are based on the value of your order. Please use the chart below to see what your shipping charge will be.

Care

The Double Red Knock Out® Rose does best in full sun or partial shade, too much shade can reduce flower development. Soil should be rich in organic matter. Amending soil by mixing your own soil with a supplemented, enriched soil can help in offering them an ideal growth environment.

Roses tolerate only mild drought, and should be watered regularly especially until established. Roses as a general rule prefer to be watered at their base, such as by a drip system. Frequently wet leaves can lead to a variety of fungal or pest problems.

Pruning is very important to promote densely growing, well producing Roses. Early spring is the optimum pruning time in most areas. Faded flowers can be snipped at any time to encourage repeat bloom (rather than seed) production.

Planting Instructions

Dig a hole approximately twice as wide as your new plant’s root ball and deep enough so that the top of the root ball is equal with the ground level.

Loosen the root ball using a small garden spade or by hand. Breaking smaller outer roots can encourage growth into the new soil, but take care to not damage large primary roots.

Place the plant in the hole and ensure that it is situated evenly upright. Use the excavated soil to fill in around the root ball, using your foot to pack it in firmly. Thoroughly soak with a hose as you fill in the dirt. Take great care to not leave any gaps or air spaces around the root ball as this could kill the plant.

A 2-4 inch layer of mulch is strongly recommended to help retain moisture and discourage weed growth. Apply mulch over the entire planting area but keep away from the stems or trunk by a few inches. Ensure that the plant and surrounding soil is completely soaked with water.

To ensure the proper nutrients are available for the life of your Double Red Knock Out® Rose, our proprietary Perfect Plants Special Blend Soil and a once yearly application of Nutricote Total 360 Fertilizer are great considerations for your new plants!

Didn’t know which roses to pick for my grandmother so I called and spoke with Natalie. She was so very helpful and knowledgeable. After telling her about where I think they should be planted at my grandmothers house, I picked the Knockout red. Can’t wait for them to ship! Customer service A+
