It sounds like a wonderful idea. Until now, my idea of garden design is to plant as many rose bushes as I can. I do pay attention to spacing them properly. Right now, I have roses in my front, back and one side yard. In the back they are along 100 feet of my back fence. I have started a second row along that same fence. The side fence is approximately 35 feet and I am already two rows of rose bushes there.
More roses are better, I say. They look beautiful in the spring and summer and fall when they are blooming. The smells of the different kinds of roses are wonderful, too.
