Resistant to black spot and downy mildew, this shrub rose is perfect for landscapes as a hedge or an accent.
Double Knock Out Red Rose Care
Plant this shrub rose in well-drained soil and provide fertilizer in the early spring for best results. Mulch in the fall to protect the roots during winter. Prune in the early spring to maintain shape.
Double Knock Out Red Rose Spacing
For a dense hedge, plant these shrub roses between 3 and 4 feet on-center. For a mass planting or informal hedge, space plants at least 5 feet center-to-center.
