What plants are best suited to Alkaline Soil?

Soil pH is an indication of the acidity or alkalinity of the soil measured in pH units. The pH scale goes from 0 to 14.

  • Neutral pH is considered pH 7.0
  • Acid soil has a pH value below 7.0
  • Alkaline soil has a pH value above pH 7.0

Most plants are happy in a slightly acidic to neutral soil measuring 6.5-7.0.
