Wonderful rose plant
Soon after I received the White Out Rose bush I planted it in my house's small border area. The planting location affords full sun and I made sure to water the bush often. I was amazed with the speed in which the bush adapted to it's new home and quickly began to flourish It's been a few months now and the bush is more than twice it's original size. Beautiful white roses are constantly blooming. I couldn't be more happy with this wonderful rose plant!
I purchased 9 of these plants. All 9 are growing well and full of blooms They started slow and I was a bit worried about them but they are all getting quite large now
Expecting them to come back
Roses were damaged in transport mulch around roots flew loose in bags wrapped around pots. While I love the white knockouts and I think they will come back I was expecting more for the investment.
Very pretty blooms
This is a very lovely rose shrub but it didn't arrive in the best condition. The leaves were dry and crispy although it did have many flowers on it. I'm hoping new foliage will grow quickly and the plant will survive
I am knocked out
These roses are beautiful and healthy adorn the front of my rowhome in planters that I painted charcoal surrounded by emerald green creeping jenny drapes
Planting & Care
A unique compact rose with dark green leaves and loads of white flowers, the White Out Rose (Rosa ‘RADwhite’) is a great addition to any landscape large or small. A small rose only reaching 3-4 feet tall/wide it is a moderate grower of 12-18 inches per year. Growing from USDA zones 5-10, they can tolerate temperatures down to -10 degrees and are heat/drought tolerant as well. They thrive and bloom best in full sun, and once established in their home they can bloom up to 9 months out of the year (depending on your location).
Seasonal information: white out roses are upright shrubs that form a tidy mound 3 to 4 feet high and bloom from June to the first hard frost. In spring, trim any broken or dead branches. You can shape the white out rose at this time. In zones with cold, wet winters, give your white out rose winter protection by planting on the leeward side of buildings or walls. Or you can wrap snow fencing loosely around the rose and cover with straw.
Selecting a location: Choose a well-drained site in full to partial sun. If you choose partial sun, make sure your white out roses receive at least six hours of direct sun a day (afternoon shade is better than morning shade). If you have clay or sandy soil, work well-rotted manure or compost into the planting site.
1) You should start by digging a hole twice as wide and twice as deep as the root ball.
2) Mix the manure or compost with the soil you have removed.
3) Back fill the soil until you have a hole the same size or slightly larger than the container the rose is in.
4) Plant the rose at the same depth as it is in the container.
5) Space white out roses plants three feet apart.
6) Mulch the planting site to retain soil moisture and keep competing growth from coming up around the rose bush.
Watering: Keep white out roses moist at all times. Water around the roots rather than overhead (or showering).
Fertilization: Fertilize with an organic rose fertilizer once a month. Use organic fertilizer rather than synthetic fertilizers as synthetics can promote weak growth and your rose will have more foliage and less flowers.
Pests and Disease: White out roses are resistant to rust, black spot and powdery mildew.
Pruning: Avoid pruning the white out roses at all in the first 2 to 3 years. Sterilize your sharp pruning shears with hot water or rubbing alcohol. This guarantees a cleaner, healthier cut. Always prune at an angle and not straight across. Activate the white out roses into growth and blooming by pruning it back a little in the spring after the last hard freeze. Keep the white out roses under control or if you want it smaller than it’s 3-feet wide by 4-inches tall size by pruning it back in the late summer or early fall. Remove dead or old canes at any time. Also cut very thin canes that might be coming up from the ground. Prune your mature plants by using the 1/3 rule each year in the spring. Remove 1/3 of the oldest canes and any stems that are damaged, diseased or dead.
