Botanix Soil acidifier

Botanix Soil acidifier



  • Intensifies the color of acidic soil-loving plants such as blue hydrangeas, azaleas and rhododendrons
  • Improves nutrient absorption
  • Excellent for small fruits like blueberries, strawberries and raspberries.
  • Lowers soil pH

This product is ideal for acid-loving plants such as cornflowers, azaleas, rhododendrons and blue hydrangeas. It allows better absorption of nutrients.

The pH (hydrogen potential) must be between 6 and 7.

  • When the pH level is lower than 6.5, as in sandy soils, the acidity must be increased by adding sulfur.
  • When the pH level is above 7.5, as in clay soils, the acidity must be reduced by adding lime.

Acid-loving plants absorb nutrients better in soil with a lower pH level, hence the use of a soil acidifier.

  • Incorporate the acidifier into the soil using a weeder.
  • Water after application.
