All summer long they bloomed and bloomed, never needed deadheading, were resistant to disease, and the deer didn’t like them. My beds are amended with lots of leaf mulch, Espoma Plant Tone and Rose Tone, mushroom compost( at least a yr old), and fine bark chips where needed to break up the clay soil. The roots of this plant are very fiberous. They need loose well amended soil to thrive. They will grow to their mature height in one season. I rarely have a problem with aphids or other rose diseases. I have chosen not to use any pesticides or insectisides as the butterflies love my envy zinnias that grow near by.
The fist year these roses are planted they will most likely get top heavy. When that happens, I cut them back to about a foot above ground so they will bush out better. As you can see from the picture below. These got top heavy indeed.
When cool weather set in and the perennials had been long removed except for that Whirling Butterflies Gaura to its right, I cut back the rose bushes back drastically. I guess that was around the first of Octoberish. Just yesterday, I snapped the pictures below and we’re already seeing new growth. We’ve had a mild winter and much needed rain in my Piedmont NC zone 7 garden. Take a look at the new shoots. Sometimes in a mild winter, I’ll get new blooms in March. It has even snowed on this rose with no worries. That’s my vegetable garden enclosed in the windows. It’s asleep right now.
The Knock Outs above are double reds and I also have Rainbow which I’m not too crazy about. Rainbow, in my garden, acts like a big ball on a stick. Imagine that if you will and then you’ll see how it flops too much. It is still pretty and covered in light pink blooms with orangish centers. You can find more information on the Knock Outs and their many varieties at the Jackson and Perkins website here.
