Something in the soil determines flower colors.
Reply:Unless the place where you bought the roses screwed up, it could be : if they are hybrid roses, and you trimmed them too hard, you may have cut back to the "original" rose. When hybrids are developed, another color is grafted to an original rose, and when combined, a different color. If you trim, you are cutting off the graft. But, most likely, there was a mistake at purchase because I never heard of a yellow rose coming from a pink one..............check back to where you bought them.
Reply:Roses do not cross pollinate in a garden setting and it is impossible for the roots to combine into the same color. Genetics simply do not work that way. It is most likely that the graft has been damaged and the plant has reverted to a wild variety. If you live in a cold climate, be sure to mulch around the plants for the winter months. Be more careful with spring pruning.
Reply:maybe the tags they had on when you bought them were wrong. Or the tags showed one color and you thought that was supposed to be the color but it was only to show the rose and the real color was on the label (pink). That is the only solution I find to it. Sorry !!!
Reply:Most likely what happen was the roots joined together and caused a dominate color to come to lite.
Reply:cross pollination will cause the flowers to change color.
