However, what you might not know is that there are several practical uses for ash, especially if you are into gardening. See below for our top 10 uses for wood ash, but first let’s look at some tips and tricks when handling ash.

What is Wood Ash?Shoveling ash - Chico CA - White Glove Chimney & Duct

Wood ash is primarily composed of calcium, potassium, phosphorus, and magnesium, but also contains trace amounts of iron, manganese, sodium, boron, zinc, copper, and molybdenum. Put more simply, it is what’s left over after burning wood, such as oak, in your fireplace. In general, ash that is the result of burning hardwoods, such as oak, is better than softwoods like pine. Never use ash from BBQ grills, pressure treated planks, painted or stained wood, or commercial logs. Ash is a very alkaline substance that needs to be handled with care. When removing ash from a fireplace, be sure to always wear gloves and goggles to keep the particles out of your eyes. Also, ash can remain hot for days after the fire has gone out, so it is important to wear gloves to keep your hands protected. If the particles are very fine, wear a dust mask to keep them from entering your lungs. Always store ash in a metal bucket with a tight sealing lid.

Ash in the Garden

Wood ash has many uses around your garden. However, you may want to steer clear of a few uses if you live in an area where the soil is already highly acidic. In general, you should try to keep the pH level of your soil between 6 and 7.5. You can find out your soil’s acidity by purchasing a soil acidity tester or by calling your local Master Gardeners.
