It can, yes.

Water source strongly influences soil pH and mineral content, so plants can be affected by acidity or alkalinity of the water source. Some plants are adapted to higher levels of salt and dissolved minerals, and even require this, while others need a more acidic pH and die if the water contains salts or alkaline minerals.

Areas with greater rainfall tend to have mineral- and nutrient-poor soil with a lower pH. Plants adapted to require more alkaline soil and/or additional calcium will require supplementation in these areas.

Examples:

  • Blueberries require acidic conditions. They’re well-adapted to wooded areas in Eastern NA where there’s lots of rainfall (which leaches salts and minerals out of the soil, leaving it slightly acidic).
  • Trying to grow potatoes in the same area will typically require you to add lime to the soil to raise the pH and provide calcium.
  • Certain marsh grasses and mangroves can handle having their roots regularly drenched with brackish water, and thrive in these conditions.
  • Hydrangeas will actually produce varying shades of either blue or pink flowers, depending on whether the pH is more acidic or alkaline (blue=acid, pink=alkaline).
