Types of soil and their pH content
In the article ‘Bonsai soils’ there is a more descriptive analysis on the different types, but in short there are 6 basic soils:
Peat soils – are comprised of waterlogged partially-decomposed plant material including sphagnum moss, which is very high in organic matter and moisture with a pH starting approximately at 3.0
Sandy soils – contain the largest particles among the different soil types, that is dry, gritty and because there large are particles creating voids, water retention is not possible. However, sandy soil warms more quickly in the spring. Sandy soils have a pH starting at approximately 4.7
Clay soils – are the remnants of certain types of rocks eroded and weathered to form fine particles, that are high in nutrients, but they can be heavy, cold and wet in winter and very dry in summer. Clay soils have pH from 5.5…
