Hydrangeas planted in containers on a shady deck were blue last summer, but are pink this year. Although we added aluminum sulfate to the plants earlier this spring, we added it too late for the first blooms to be blue.
Over the years I planted hydrangeas in the ground without any success. The plants always eventually died after struggling during the long hot, dry summers and heavy clay soils in north Texas. Then I discovered hydrangeas kept in large containers on the shady deck and porch not only survived, but bloomed!
