How to use wood ash in your garden

Did you know that ash from wood-burning stoves and fireplaces is good for your garden? Wood ash is rich in potassium and other minerals that growing plants need. It’s also highly alkaline, which makes it an ideal substitute for lime when your soil is too acidic.

Before using ash in your garden, make sure it isn’t derived from painted or varnished wood, charcoal or fake logs.

You should also do a soil test. If your soil already has a pH of seven or higher, it’s best to avoid using ash so that the ground doesn’t become too alkaline for plants to thrive in.

Sprinkle cooled ash over your lawn to promote grass growth, or place a few handfuls around hardwood trees to provide vital nutrients. Ash is also excellent for adding to vegetable beds, especially around tomato plants, which require extra potassium. Avoid putting it near acid-loving plants like blueberries, rhododendrons, marigolds and potatoes.
