Changing the Color of Your Hydrangeas Hydrangeas turn blue as a reaction to aluminum in the soil. The soil pH should be slightly acidic (5.2 - 5.5). Do a soil test first, to determine your starting pH. Adding aluminum sulfate to the soil will help lower its pH, if necessary. A word of caution: not all plants can tolerate acidic soil and neighboring plants may be adversely affected.

Hydrangea Tree Leaves Turning Yellow Often leaves will yellow due to the transplanting process. The cooler fall temperatures could be sending the plant into dormancy as well. As John suggested, keep the soil damp or moist but not wet. Once the hydrangea has lost it's leaves there won't be as much of a need for supplemental water. If there is long term drought you'll want to provide some water, especially before a serious drop in temperature. During winter, and in the event there is dry soil and temps below 32F, the roots can become freeze dried.
