  • 2 tbsp soil from your garden
  • 1/2 cup vinegar
  • 1 tsp distilled water optional, only if needed
  • 1/2 cup baking soda


  • Start by collecting soil samples from different areas in your garden.
  • Put about 2 spoonfuls of soil into different containers.
  • Add 1/2 cup vinegar to the soil. If it fizzes, you have alkaline soil, with a pH between 7 and 8.
  • If it doesn't fizz, add a little bit of distilled water to the other container of soil – just enough to make it muddy.
  • To that, add 1/2 cup of baking soda. If it fizzes, you have acidic soil, with a pH between 5 and 6.
  • If the soil doesn't react to either vinegar or baking soda, you have neutral soil (which is the best soil to have!).
