Yes, wood ash can be used as an organic fertiliser, primarily as a source of potassium and trace minerals. It also raises soil pH, so it's beneficial for acidic soils but should be used sparingly in alkaline soils. Only use ash from untreated wood. Apply it lightly as a top-dressing or mix into compost. Avoid using large quantities directly, as its alkalinity can be too strong for some plants. Do not use ash from charcoal or treated timber.
