More Information

Description The White Knock Out® rose (Rosa) packs a punch with abundant, continuous blooms for over five months. A flurry of snow-white flowers pops above dark, near-black foliage. When flowering finishes at frost, decorative orange-red hips decorate the shrub. Let your rose do all the hard work as it self-cleans spent flowers. No maintenance is required! The disease-resistant series of Knock Out® roses have taken the world by storm. Black spot, powdery mildew, and numerous other typical rose ailments won't touch these roses. Details Botanical name: Rosa 'Radwhite'

Uses: Accent, Border, container gardening, cottage gardening, drought tolerant, foundation planting, ground cover, hedge, massing, ornamental, specimen
How To Grow Soil: Prefers moist, slightly acidic, well-draining soil. Roses benefit from the addition of compost, aged manure, or leafmold to the planting soil.
Light: Sun (> 6 hours sun)
Water: Try to keep the soil evenly moist, especially in their first growing season. Never allow the foliage to remain wet into the evening; water early in the day.
Spacing: 3 - 4 ft.
Fertilizing: To keep the flowers coming, feed your roses with a fertilizer blended especially for roses. This can be done after each bloom cycle.
Winterizing: Spread a layer of composted manure, compost, or shredded leaves over the base of the plant in late fall after the ground freezes. Covering these mounds and the lower parts of the bushes with evergreen boughs will add protection. Pull the mounding material away from the stem as new growth emerges in spring. Prune injured branches over when new buds emerge in spring.
Maintenance & pruning: Prune to remove deadwood, to control or direct growth, and to promote flowering. Wait until growth breaks in early spring before pruning. Every 2 or 3 years, remove about one-third of the old branches to stimulate new, fresh growth. There is no need to remove faded flowers because these roses are self-cleaning.

Outstanding!

I am very pleased with my purchase and my plants are already blooming. I will say I didn't understand the size of 'quart' when I purchased. So the plants were smaller than I expected. But they are all very healthy and thriving. Highly recommend!

Going to be a good thing

Shipment arrived faster than I thought, all well packaged. Followed instructions, planted and watered for 2 weeks. And they seem to be doing very well, even at their small size we are getting blooms. It’ll be fun to watch them grow to their full size.
