Although soil pH can affect the color of hydrangea flowers, to my knowledge it won't affect a rose bushes bloom color. Roses prefer a slightly acidic soil pH, ideally between 5.8 and 6.2. A soil pH that is too high or too low interferes with or prevents the chemical reactions that make nutrients available to plants.Why has my Yellow Rose turned white?
