The colour of hydrangeas is affected by the pH of the soil - soils with a low pH (up to about 5.5) are acidic soils and will produce blue or purple flowers. Soils with a high pH (above 5.5) are more alkaline and flowers tend to become pink as the pH increases.
Many modern Hydrangeas are bred to be more inclined to either blue or pink, but in my experience they usually eventually revert to the above 'rule'.

To protect next year's growth, cut hydrangea blooms in the fall only if you're dealing with spent flowers on certain varieties, like the smooth hydrangea (Hydrangea arborescens) or the panicle hydrangea (Hydrangea paniculata). Make cuts just above the first set of healthy buds on the stem, typically around 12-18 inches from the ground. Avoid cutting the older wood on varieties like bigleaf hydrangeas (Hydrangea macrophylla), as they bloom on old wood and cutting them back can reduce flowering the next season. Always use clean, sharp tools to make clean cuts and reduce the risk of disease.
