About Double Knock Out Rose
Double Knock Out Rose offers the same continuous spring-through-frost bloom and strong blackspot resistance as the original Knock Out Rose, but with fuller, double-petaled cherry-red flowers instead of the single 5-petal blooms of the original, giving a showier, more traditional rose appearance while keeping the low-maintenance, self-cleaning traits that made the series famous. It grows to the same compact 3-4 feet tall and wide, fitting easily into foundation beds, mixed borders, or mass plantings along a Lawrenceville driveway or walkway. Like the original, it demands full sun, at least 6 hours daily, for its heaviest bloom and best disease resistance, and tolerates Georgia's clay soil well as long as drainage is adequate. Its extended bloom season, flushing roughly every 5-6 weeks from spring until the first hard frost, provides more months of color than almost any other flowering shrub sold in our region, with none of the fungicide spraying traditional roses typically require in humid Southern summers.

Planting Instructions & Regional Tips
Plant Double Knock Out Rose in full sun in well-drained soil, mounding slightly in heavy Georgia clay to avoid root rot. Space 3-4 feet apart for hedging or mass color. Water deeply weekly during the first season, tapering off as roots establish. Prune by about one-third in late winter to rejuvenate growth and maximize the season's bloom production. Once established in a Gwinnett County landscape, it needs only occasional deep watering during dry stretches rather than a regular irrigation schedule.

Double Knock Out Rose FAQs
What is the difference between Knock Out Rose and Double Knock Out Rose?
Double Knock Out Rose produces fuller, double-petaled flowers with more petals per bloom, while the original Knock Out Rose has simpler single 5-petal flowers. Both share the same continuous bloom season, compact 3-4 foot size, and strong blackspot resistance.
Do deer eat Double Knock Out Rose?
Yes, Double Knock Out Rose is not considered deer resistant and can be browsed by deer, especially newly planted specimens. In Gwinnett County areas with heavy deer pressure, fencing or repellent application is worth considering until the plant is well established.
