Description

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.

How To Care

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.

Very happy with my first online plant purchase

I bought three roses that came in amazingly good shape. They were packed to protect the plant above the soil line of the pot. Very full, lots of buds. I wasn't expecting much, but since I couldn't find these roses anywhere near me, I went with it. Very happy with my purchase.

Yellow and white knockout roses

Roses were received quickly, well packaged and appeared healthy. Planted immediately and mulched well. Appear to be doing well. Hoping they will survive colder temps that began this week.

Gregory, roses at this time of the year (Fall) are starting to shed their leaves and go dormant. However, keep them watered and they will be beautiful come spring.

Grt plant

I have never ordered a plant online and was very skeptical. I am a master gardener and I'd like to go To the nursery and see things in person. Was unable to find a white knockout anywhere in the city so I took a leap of faith and ordered online. And very please with the outcome it came in good shape oh is in the ground and seems to be doing well. I would order again.
