petals changing colour.
I'm not the worlds best gardener. I plant.. things grow. I have several bush roses in my garden, and a couple of climbers that are doing well.
However, a work colleague of mine asked for my advice and described an oddity with her roses. She has plants that she planted 5 yrs ago, which produced blooms that are Coral in colour. This year her blooms have produced red petals and she is wondering why. I was thinking maybe her bushes have reached a maturity and hence the change. Any help and suggestions would be quite welcome;
