Coal Ashes In The Garden
Categories:
Soils, Fertilizers and Irrigation
What is the effect of coal ashes on the red clay soil of Redlands or
wood and coal ashes combined?
Coal ashes are exceedingly desirable upon clay land because their
mechanical mixture with the fine particles of the clay renders the soil
more friable, permeable and better adapted to the growth of most plants.
Coal ashes, however, possess no fertilizing value - their action is
merely mechanical. The wood ashes which may be combined with them are
desirable as a source of potash which most plants require.
