Burning your scrap wood in the winter months can provide a source of heat and an opportunity to gather friends and family around the fire. It’s a great way to clear brush build up and keep your home warm on cold evenings, but why stop getting good use out of your wood there?

Wood ash has been around for hundreds of years as a useful and natural ingredient to use as a resource around the house and outdoors. With the power to boost nutrient levels in soil, repel insects, and more, wood ash is a hardy staple of any savvy homesteader and was even appreciated by our forefathers. In fact, a handy bit of wisdom you can use to impress your friends is that the method of using wood ash as a fertilizer was the first U.S. patent.

1. Wood Ash for Nourishing Plant Life

If you’ve been researching ways to infiltrate your soil with some helpful nutrients, you’ve probably come across a bevy of commercial lime treatments. Wood ash is a natural and easy way to treat your soil and boost its acid levels—and you and your plants can enjoy the nutritious benefits without a trip to your local garden center.

Wood ash is superior to lime in other ways as well. The amount of nutrients returned to the earth from wood ash are much greater and diverse. Wood ash is a wonderful source of lime, potassium, calcium, and a plethora of other essential nutrients for plant growth.

If you’re thinking your garden could use a beneficial boost, the first step in treating your soil is with a pH test. If you find that your levels are low in acid, then a wood ash sprinkling around your yard could do your plant life some good.

Wood ash from hard wood is the best to use when it comes to treating your soil and adding nutrients. This is mainly due to the fact that hard woods contain more nutritional substance.


The amount of wood ash that you will need to apply will be anywhere between one and a half to twice as much as the recommended lime treatment. To add to the soil, sprinkle lightly and gently rake into the soil making sure not to damage any root systems.

You can use this treatment in flower beds, on lawns, for shrubs and even for aquatic plants. For your water plants, add one tablespoon per 1,000 gallons of water. Tomatoes love the extra calcium boost too. Wood ash can help protect plants against frost, but use in the springtime can be tricky because young plants often can’t take the drastic change in pH.

Use your wood ash in the fall for best results. If your soil is not poor in acid, then it is probably safer to forego any wood ash treatment. Certain plants thrive in low acid conditions. These include blueberries, rhododendrons, mums, marigold, oak, potato varieties, azaleas, and more.

2. Compost

A sprinkling of wood ash adds nutrients to compost and also helps to balance and stabilize the conditions of the compost for optimal microorganism growth. A little goes a long way, so be sure to use a light sprinkle of wood ash every once and awhile instead of a large dose of this powerful compound.

3. Insect Repellant

If you have an alkaline soil, you may be able to use wood ash liberally enough to even control your pests with it. Wood ash draws water from the bodies of invertebrates such as ants, snails, slugs, and other insects. For this purpose, apply dry wood ash to problem areas or around plants that you wish to protect.
