For a low-maintenance and compact flowering shrub, it is hard to beat a Knock Out® Rose. The White Knock Out® Rose brings all the elegance and beauty of a white rose without the muss and fuss of rose growing. Extremely disease resistant and petite in size, the White Knock® Out is sure to liven up your garden with its soft white petals and gold stamens. The nearly black leaves allow those bright white blooms to really stand out and make a statement! This Knock Out® rose blooms from May to October, giving your garden a consistent beauty and attracting swarms of butterflies and bees. 

The White Knock Out® Rose grows to be 3-4 feet tall and wide, making it a great fit for gardens of any size. Knock Out® Roses are bred specifically to be more disease resistant than the average rose, allowing them to be more low maintenance for the average gardener. This hardy rose has a slight citrusy scent and is a great addition to a cut-flower garden. 

White Knock Out® Rose Care

The White Knock Out® Rose tends to bloom and grow best when provided with full sun and regular deep watering, especially in hotter and drier periods. Knock Out® Roses can be planted in neutral, well-draining soil. To plant it, dig a hole that is twice the width and of equal depth as the root ball. If the soil is sandy or clay, amend with compost or soil conditioner to ensure adequate drainage. In the spring, feed the White Knock Out® Rose with a balanced fertilizer formulated for roses.

To maintain the size and shape of a Knock Out® Rose, cut it back to about 12 inches in late winter or early spring. Remove dead or damaged wood at any point in the year to reduce the risk of disease and improve air flow. When watering, avoid wetting the leaves to prevent foliar infections. Spent blooms and rose hips can be removed as well to improve the look of the bush and encourage additional blooming. 

White Knock Out® Rose Spacing

Plant the White Knock Out® Rose 4 to 6 feet away from other plants to allow for room to grow. When planting as a hedge or en masse, Knock Out® Roses can be planted slightly closer together. The White Knock Out® Rose can be kept in a container that is at least twice the size of the root ball with adequate drainage, though it is important to place the container in a protected spot during the winter to prevent root damage.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)

We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Guarantee and Warranty

Plant Shipping

Below are some factors we consider when determining when to ship the plants depending on the timing of the order.

Winter to Early Spring

We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.

Summer

If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.

Fall into Winter

We’ll ship plants out all the way up to the end of the fall planting season!

Winter

Get your order in early to reserve your plants for Spring planting!

Once your plant is shipped you’ll receive an automated email with tracking information.
