Double Knock Out Rose Shrub

Double the Petals on Double the Roses

Why Double Knock Out Roses?

Boasting one of the longest blooming periods available, from early summer to late fall, the Double Knock Out Rose gives you all the amazing characteristics of the original Knock Out Rose – just with more petals and even better disease resistance.

Even better? Not only is this cultivar more resistant to black spot, rust, and mildew, but it’s also more resistant to insects. That means the Double Knock Out is virtually maintenance-free, especially since it grows thickly without pruning. Plus, it thrives in containers or in the ground.

Each of the varieties in the brand are disease resistant, require minimal maintenance, and produce continuous blooms that last from spring to fall.

Planting & Care

1. Planting: Choose a well-drained site in full to partial sun (4 to 8 hours of sunlight per day). If you choose partial sun, make sure your plant receives at least 6 hours of direct sunlight each day (afternoon shade is better than morning shade).

Start by digging a hole twice as wide and twice as deep as the root ball. Backfill the soil until you have a hole the same size or slightly larger than the container the rose is in. Plant the rose at the same depth as it is in the container. Space Knock Out Roses 3 feet apart. Mulch the planting site to retain soil moisture and keep competing growth from coming up around the rose bush.

2. Watering: Keep Knock Out Roses moist at all times. Water around the roots rather than overhead (or showering). Generally, this means watering about once or twice weekly, or more often in dry conditions.

3. Fertilizing: Fertilize with an organic rose fertilizer once a month.

4. Pruning: Prune every spring, all the way back to 12 inches off the ground, after it is established. When you do prune, sterilize your sharp pruning shears with hot water or rubbing alcohol. This guarantees a cleaner, healthier cut. Always prune at an angle and not straight across.
