To safely dispose of ashes from your stove, it’s important to handle them carefully to avoid fire hazards. Always make sure you allow the ashes to cool completely. Never rush this step, as hot embers can remain hidden within the ashes and pose a fire risk. Store the ashes in a metal container, away from any combustible materials.
Because of the potential toxicity of coal ash, the safest option to dispose of it is at a landfill and avoid using it in your garden, compost, or for other household uses. On the other hand, ashes from burning untreated wood can have many beneficial uses. Here are some ideas:
Compost
Wood ash can be added to your compost pile in small amounts. It’s a good source of potassium and other minerals that can enrich the soil. However, make sure not to add too much, as it can raise the pH and make the compost too alkaline.
Garden Fertiliser
Wood ashes contain nutrients like potassium, calcium, and magnesium, making them beneficial for plants. Spread it lightly over your garden beds or mix it into the soil. Be careful around plants that prefer acidic soil (like blueberries, rhododendrons or other ericaceous plants), as wood ash can raise soil pH. On the other hand, roses will love your wood ashes. A little goes a long way, mix a small amount of ashes into the top few inches of soil around the rose bush, avoiding direct contact – try not to let it touch the stems or leaves of the roses, as it can be a bit caustic.
De-icing driveways, pavements and patio slabs
During winter, as a more economical alternative to using salt, you can use wood ash to help melt ice on your driveway or walkways. It also provides traction when sprinkled on slippery surfaces.
Pest Control
Wood ash can help deter pests in the garden, like slugs and snails. Sprinkle it around plants you want to protect.
Cleaning
Wood ash can be used as a mild abrasive for cleaning. It can be mixed with water to clean glass and metal surfaces or scrub tough stains on cookware. Using very fine ashes, you can create a paste which will work wonders cleaning your stove glass window from any residue and burnt stains.
Use in Natural Dyeing
Some people use wood ash in fabric dyeing for creating unique shades, often in combination with other natural materials.
Just be sure the ashes have cooled completely before handling them. Also, avoid using ashes from treated wood, as it can contain harmful chemicals. For disposing of coal ash, it’s best to follow your local guidelines.
