Rosa 'Radtko'

Double Red Knock Out Rose brings a generous show of full red flowers to sunny beds with less fuss than many traditional hybrid tea roses. Rounded shrubs are especially effective planted in a row, where their repeating color defines paths and borders.

Why Gardeners Love Double Red Knock Out Rose

- Full red flowers: Double blooms have a rich, layered look

- Repeat flowering: Successive flushes brighten the warm months

- Hedge potential: Several shrubs make a colorful informal boundary

- Deep green foliage: Leaves provide a backdrop for the red flowers

- Easy-care character: Good disease resistance reduces—but does not eliminate—routine upkeep.

Where to Plant Double Red Knock Out Rose

Give this rose at least six hours of sun and a location with moving air. Plant in well-drained soil and leave enough room for its mature width.

Growing and Care Tips

Water at the base, mulch to conserve moisture, and prune in late winter or early spring. Remove damaged canes promptly and keep fallen diseased leaves out of the bed.
