Moreover, what is the pH of wood ashes?

4.5 to 6.0

Likewise, why is wood ash alkaline? The main benefit of wood ash in the soil is to raise the soil pH, or make it less acid. Soil pH is a measure of acidity on a 14 point scale, with 7 being neutral. Below 7 is acid, and above is alkaline. Most our northeast soils tend to be acidic, often 5.5 to 7.

Also question is, which plants like wood ashes?

Are human ashes good for plants?
