The Ideal Soil pH for Cedar

Cedar: Optimal pH Range and Its Importance

Cedar trees (Cedrus spp.) thrive in a soil pH range of 6.0 to 7.0, preferring slightly acidic to neutral conditions. This pH range is optimal for Cedar’s nutrient uptake and overall health. Within this range, Cedar can effectively absorb essential nutrients, particularly nitrogen, phosphorus, and potassium, which are crucial for its growth, needle development, and wood formation. Cedar’s adaptability to various soil conditions contributes to its widespread use in landscaping and forestry. While Cedar can tolerate a slightly wider pH range (5.5 to 7.5), maintaining the ideal range ensures the best growth and longevity. In highly acidic soils (below 5.5), Cedar may experience reduced nutrient availability, especially calcium and magnesium. In alkaline soils (above 7.5), the tree might suffer from iron and manganese deficiencies, leading to chlorosis. Proper pH management is essential for promoting robust growth, maintaining the characteristic fragrance of the wood, and ensuring the tree’s resistance to pests and diseases.

Cedar: Methods to Adjust Soil pH

To Lower pH for Cedar:

  • Elemental sulfur
  • Aluminum sulfate
  • Iron sulfate
  • Organic mulch (e.g., pine needles, oak leaves)

To Raise pH for Cedar:

  • Agricultural lime
  • Dolomitic lime
  • Wood ash (in small amounts)
  • Bone meal
