What happens to wood ash when it gets wet?

While wood ashes are considered nontoxic, they contain alkaline material in the form of potassium carbonate and potassium hydroxide, often referred to as pearl potash and potash, respectively. These compounds are very soluble in water and react with water to release hydroxide ions which can produce a pH as high as 12.

Does ash ruin soil?

Applying small amounts of wood ash to most soils will not adversely affect your garden crops, and the ash does help replenish some nutrients. But because wood ash increases soil pH, adding large amounts can do more harm than good.
