Do any of you know much about how to control the color of Hydrangeas? I know you can add stuff to the soil to help control what color they will be but I'm not real sure just what and how much. Just wondered if anyone here might have grown some and had good luck with them.
Not all hydrangeas can be color-controlled, but there are some that will be blue in an acidic soil and pink in an alkaline soil. I have some in the turn-around with my blueberries and rhodendrons. Because the turn-around has an acid soil, the hydrangea should/will be blue once they flower. I had severe drought conditions last year when I planted them and so far they are recovering but not blooming.
