Knock Out® White Rose

The Knock Out® White Rose is not your everyday rose bush. With self-cleaning, re-blooming, white blooms for longer periods of time, this rose bush will be sure to knock your socks off. Virtually maintenance free with no deadheading required, this rose bush maintains a beautiful round and bushy shape. Stunning white roses are prominent on this bush from spring all the way to late fall. That’s over 6 months of blooms with no maintenance required!

The Knock Out® White Rose prefers full to partial sun with regular watering. It is recommended to water weekly for a profusely blooming bush from spring all the way to late fall. Maintaining a nice bushy shape, the White Out Knock Out can reach a mature size of 3 to 4 feet high and wide. Not only does this rose bush bloom multiple times, but it is also resistant to many diseases such as black spot and powdery mildew.

The Knock Out® White Rose makes a great companion to ornamental plants, it can be used as a nice backdrop to intensify season long color. Whatever the need may be, the ever producing snow white blooms of the Knock Out® White Rose bush will be sure to gracefully add color to your landscape.

Be sure to select the right location for your Rose bush.

Planting Time: Any time of the year, taking care to avoid the most extreme temperatures in winter and summer.

Sun: Full to part sun

Soil: Adaptable, but not overly sandy. Well drained

Watering: Water in well when planting. Keep soil moist for the first month. Once established, allow soil to dry before watering.

Fertilizing: Slow release fertilizer twice per year in early spring and again in summer.

Pruning: Drift and Knockout Roses do not require pruning. However, pruning can help maintain vigor and strength as well as encourage better blooming. We recommend pruning back, leaving about 1 foot for Knockout Roses and pruning about 1/3 to 1/2 back on Drift Roses.

Our Knock Out® White Roses are forever blooming with pure white blooms. They are great in a natural area, to accent other plants, or used in a backdrop. Space your new rose bushes about 4-6 feet apart when planting in clusters or anywhere you want space between plants and 3-4 feet apart when planting a hedge. These hardy roses can be used just about anywhere.
