Double Knock Out Rose
Rose x 'Radtko' PP#16202
Very much like the original but with stunning double flowers in rich magenta red, slightly more compact than the single Knock Out
Plant Type(s): Flowering Shrub, Rose
Spring/Summer Care: Trimming lightly in late summer can increase autumn blooms, but is not necessary.
Autumn/Winter Care: Shear back by 2/3 after all foliage has dropped.
Fertilizer Needs: Apply a slow-release fertilizer in spring and again in summer. There are also a number of fertilizers tailored for Roses, most of which will work perfectly fine.
