Planting and Care Guide

Planting Tips

Plant in well-drained soil. Dig a hole twice as wide as the root ball. Space 3–4 feet apart. Water thoroughly after planting and mulch 2–3 inches deep, keeping mulch away from the canes.

Care Tips

Water deeply and regularly the first season. No deadheading required for continuous bloom. Prune back by one-third in early spring. Fertilize with a balanced rose fertilizer in spring and midsummer. Outstanding disease resistance makes this a very low-maintenance rose. Monitor for black spot and rose sawfly. The white flowers with a soft yellow center are clean and elegant, produced continuously from spring to frost. A reliable, carefree alternative to the red Knock Out for lighter-colored landscape schemes.
