Wood ash has a very high potassium carbonate content, which makes it an excellent choice as a fertilizer. In addition to potassium, wood ashes are a rich source of phosphorus, calcium and magnesium. Additionally, it contains small amounts of:
All of these elements are essential for new plant growth, so it’s no wonder that wood ash has been a very popular organic matter and natural fertilizer for so many centuries.
#2 – Balance Your Soil pH
Wood ash is very valuable for neutralizing acidic soil. Conduct a soil test to determine the soil acidity levels.
If the soil test revealed that the pH measurement of your soil is below 6, it is too acidic for many plants. It will need to undergo soil amendment with potassium, phosphorus and nitrogen. All of these elements are naturally occurring in wood ashes.
#3 – Lime Substitute
You can also substitute wood ashes for lime, which is often used to amend soil lacking in calcium carbonate. The addition of wood ashes can lower and raise soil acidity aka soil pH.
Be careful when using wood ashes on acid-loving plants like azalea flowers, rhododendrons, blueberries, ixoras, and in the growing of gardenia.
The benefit of using wood ash instead of lime is that it breaks down quickly and is more bioavailable to your plants. Generally speaking, you should use 25 pounds of natural wood ash per 1,000 square feet of garden soil.
Be sure to test your soil frequently to avoid overdoing it.

All birds like to roll around in the soil to clean their feathers and discourage mites and lice. A combination of wood ash and sand makes an excellent chicken dust bath.
Additionally, as the chickens preen themselves they will take in some of the nutrients in the wood ashes, and this will result in more nutritious eggs and stronger egg shells.
#2 – Make Old-Fashioned Lye Soap
Using wood ashes the old-fashioned way to make lye soap. Good homemade lye soap consists of a combination of animal fat and lye. Lye is made by boiling hardwood ash in soft water. This produces potassium hydroxide (lye water).
When potassium hydroxide is combined with animal fat, a soft soap results. Salt can be added to this mixture to make a more firm soap.
Before trying this, be sure to study the process thoroughly. Making soap can be a bit complex, and it can also be dangerous. Don’t undertake this unless you know what you’re doing.

Select & Handle Wood Ash Carefully
Be sure to only use ash from natural, untreated wood. Avoid CCA-treated wood dust to fall over your garden plants or compost. The very best type of wood to use when sourcing wood ash for use in your garden is hardwood.
The reason for this is that maple, oak and other hardwoods contain far more nutrients than softwoods.
In fact, it is important to note that wood ash is so nutrient rich that it is not advisable to use it on young seedlings because the salts it contains can be damaging to young garden plants.
Additionally, you should not combine wood ash with fertilizers containing nitrogen. This wood ash and nitrogen combination creates dangerous ammonia gases.
When sourcing ash for use in your home and garden, be sure to follow proper safety procedures.
Allow ashes to cool completely before handling them. Store them in a metal container with a tightly fitting lid to prevent spontaneous combustion.
