Adjusting Soil pH for Privet Hedge in Acidic Soil

Target pH 6.0–7.0

Privet (Ligustrum) prefers neutral to slightly acidic soil. If your soil is below 6.0:

Amendments to Raise pH

  • Gypsum (calcium sulfate): Apply per package directions. Improves clay structure without drastic pH shift.
  • Wood ashes: Light application (5–10 lbs/100 sq ft) raises pH and adds potassium.
  • Sawdust (aged): Incorporates slowly, buffers acidity.

Application

Spread evenly around hedge drip line. Water in. Retest in 6 months. Avoid lime unless soil test confirms need—privet tolerates slight acidity.
