Product Description

As the original members of the Knock Out family, the Red KnockOut Rose bush adds not only a continuous burst of rich cherry red color but also a light sweet scent to your garden!

This cultivar’s bright red flowers bloom continuously and proliferously. Like the other Knock Out rose varieties, the red knockout rose tree has extraordinary resistance to common rust and powdery mildew, and resistance to black spot foliage diseases. Although resistant, they are not immune and need proper care to prevent these problems from occurring.

The bloom cycle for these flowering shrub roses starts in early spring and reblooms all summer long. Roses require deadheading spent flower blossoms to encourage continuous blooming.

This beautiful rose bush makes for a superb low hedge. It could also be planed as an accent shrub. The dark, semi-glossy foliage contrasts nicely with the bright blooms of the roses creating visual appeal in any landscape.

Rose Bush Care

This red rose bush can grow up to 3-5 feet tall and 3-4 feet wide. Dig a hole the size of the root ball and water thoroughly the first year of planting to establish a strong root system. After it is established, it is fairly drought tolerant. Grow roses in full sun although they can tolerate partly shaded areas.

Grow this knockout rose across the United States in USDA hardiness zones 5-10. Has very good winter hardiness for the northern states, although winter protection may be necessary for areas with extremely cold winters.

No special care is needed besides an annual application of slow release fertilizer or organic fertilizer at the top of the root ball. It can help during the growing season to encourage flowering. Fertilize your rose bush in early spring. Our Rose Soil Mix will work wonders for your new rosh bush when amending the soil.

Prune your rose bush in spring or fall to maintain desired size and shape. You can even prune this rose into a knock out rose tree. These flowering trees are versatile and can be grown in a variety of ways.

Shipping Info

Once your Red Knock Out® Rose Bush 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 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 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!

I purchased these for my parents and my parents were absolutely amazed at the size of the plants, how healthy the plants are and the blooms already on the plants.
My parents didn’t think they would be able to get the roses, because of Covid19 and their age, they couldn’t go out to shop.
Thanks to your website I was able to please my Parents for Mother’s Day and Father’s Day.
Thank you
Lucy
