Why Soil pH Matters for Your English Yew’s Health

by

English Yews (Taxus baccata) are popular evergreen shrubs known for their lush foliage and versatility in landscape design. Maintaining their health requires attention to various environmental factors, one of the most important being soil pH.

Understanding Soil pH

Soil pH measures the acidity or alkalinity of the soil on a scale from 0 to 14. A pH of 7 is neutral, below 7 is acidic, and above 7 is alkaline. Different plants thrive in specific pH ranges, and English Yews are no exception.

Ideal Soil pH for English Yew

English Yews prefer slightly acidic to neutral soil, with an ideal pH range of 6.0 to 7.0. Maintaining soil within this range promotes optimal nutrient uptake and overall plant health.

Effects of Incorrect pH Levels

If the soil pH is too low (acidic), the yew may experience nutrient deficiencies, leading to poor growth and increased susceptibility to pests and diseases. Conversely, overly alkaline soil (high pH) can cause deficiencies in essential nutrients like iron and manganese, resulting in yellowing foliage and weak growth.

Signs Your Soil pH Is Off

  • Yellowing or pale foliage
  • Stunted growth
  • Poor overall vigor
  • Increased pest problems

Testing and Adjusting Soil pH

Regular soil testing helps monitor pH levels. Soil test kits are widely available and easy to use. Once you know your soil’s pH, you can take steps to adjust it if necessary.

How to Lower Soil pH (Make it More Acidic)

  • Incorporate elemental sulfur
  • Add iron sulfate
  • Use acidifying organic matter like pine needles or peat moss

How to Raise Soil pH (Make it More Alkaline)

  • Add lime (calcium carbonate)
  • Use wood ash cautiously
  • Apply crushed oyster shells

Adjusting soil pH is a gradual process. Regular testing and careful application of amendments ensure your English Yew remains healthy and vibrant.

Conclusion

Maintaining the correct soil pH is essential for the health of your English Yew. By monitoring and adjusting soil pH as needed, you can promote vigorous growth, vibrant foliage, and long-lasting beauty in your landscape.
