Wood ash is the powdery residue remaining after the combustion of wood, such as burning wood in a fireplace, bonfire, or an industrial power plant.
- It is largely composed of calcium compounds along with other non-combustible trace elements present in the wood.
- It has been used for many purposes throughout history
- Plants that thrive with a dressing of wood ash include garlic, chives, leeks, lettuces, asparagus and stone-fruit trees.
- Do not spread ashes around acid-loving plants like blueberries, strawberries, azaleas, rhododendrons, camellias, holly, potatoes or parsley
- Ash from wood fires, such as bonfires or wood burning stoves, can be a useful additive to the compost heap or can be applied directly to fallow ground and dug in. It can be a natural source of potassium and trace elements.
- Too much wood ash can change the pH of the soil drastically, which can kill the plants living in it
