How pH Affects Plant Growth in Gardens

  1. Soil pH controls how easily plants can absorb essential nutrients.
  2. Most garden plants thrive in slightly acidic to neutral soil, between pH 6 and 7.
  3. Acidic soils can lock up nutrients like phosphorus, stunting growth.
  4. Alkaline soils may limit access to iron and manganese, causing yellowing leaves.
  5. Blueberries, azaleas, and rhododendrons love acidic soils below pH 6.
  6. Vegetables like beans and lettuce prefer near-neutral conditions for best yields.
  7. Adding lime raises soil pH, making it less acidic for struggling plants.
  8. Sulfur or organic matter can lower soil pH, helping acid-loving plants thrive.
  9. Regular soil testing helps gardeners adjust pH before problems appear.
  10. Balanced pH creates healthier roots, stronger plants, and bigger harvests.
