All they will be blue?
Last year, I planted a pink, a red and a blue hydrangea on the front flower bed. They all demaged by late frost and they were very small (cheap mail-order), so no flower last summer. As I've learned more about hydrangea, no matter what the manufacturer said, the color of the hydragea is mainly affected by the soil. I live in New England, the soil is acidic, are all those hydrangea will be blue if I don't add lime to the soil? I forgot label the hydrageas, so it's no way to know which is which if they all come out to be blue? I want to have a cold color theme in the same bed for summer, and I want to move the pink and red hydrangea to other locations. Will the pink and the red be a slightly different color as the blue one even they are in the same bed?
