Why Do People Use Wood Ash as a Soil Amendment?
People use wood ash as a soil amendment for various reasons. Those who have fireplaces in their homes are more likely to use wood ash because it is easily accessible and convenient. If you are already burning wood in your fireplace, you will have plenty of wood ash left in the fireplace. You could scoop it out, add it to a container, and sprinkle it over your soil. It is truly that simple!
When someone uses wood ash in the soil, they use it for more than just convenience purposes. It is also because the wood ash contains alkaline properties. The added alkaline in the soil can prevent the soil from being too acidic. You do not want soil that is too acidic because it could disrupt the growth of various fruits, vegetables, and flowers that you have planted in the ground.
The Advantages of Using Wood Ash in Soil
There are quite a few advantages associated with the use of wood ash as a soil amendment. Some of the advantages include:
- Recycling the ash. Instead of tossing ashes from your wood stove or fireplace in the trash, you will put it to good use by placing it on top of the soil and using it to get your plants to grow even more.
- Provide your plants with potassium and calcium. Because the wood ash typically contains both potassium and calcium, adding it to the soil will provide your plants with these essential nutrients.
- Encourage healthy growth of various plants. While wood ash is not the best amendment for all plants, it is an excellent addition to the soil for specific plants. Some of these plants include various types of lettuce, asparagus, garlic, and chives.
- Easy to access. If you are burning wood, you have instant, easy access to wood ash. You do not have to worry about spending more money on a soil amendment.
- Reduce the acidity levels of the soil. Some plants do better with less acidic soil. In that case, it helps to use wood ash for its alkaline properties to get the soil down to a neutral level.
With advantages like these, it makes sense why some people choose to use wood ash as a soil amendment. It is a great alternative to other soil amendment options.
The Disadvantages of Using Wood Ash in Soil
Although many advantages exist, it is important to know about some of the disadvantages associated with the use of wood ash in soil. Some of the disadvantages include:
- Does not work well with certain plants. When growing plants that thrive in acidic soil, such as strawberries, blueberries, and potatoes, it is better to skip out on using wood ash on your soil.
- It may contain some heavy metals. While wood ash is great to use in the garden, there are times when it may contain heavy metals that are not good to have around your plants. It can even include some lead, which is not something you would want to consume when growing vegetables and fruits.
Despite the minor disadvantages, wood ash is still a good amendment for some occasions. It all depends on what you are growing in your garden. When used in soil with the right plants, wood ash can make drastic improvements to your crop production.
Which Wood Types Are Best to Use?
Not all wood burns the same. For that reason, you should know which types of wood are best to use when you have plans to put the ash in your soil.
It is crucial to avoid chemically treated lumber.
The treatment may contain toxins that are bad for the soil and bad for the plants you are growing. However, if you have traditional firewood that you cut down on your own, it is safe to use the ash from that wood in your soil. If you buy firewood from a store or an individual who chops trees down in their spare time, ask questions about chemical treatments and additives. Asking these questions will help you find out more about the wood you are using.
Is Wood Ash a Good Soil Amendment?
Wood ash is good to use as a soil amendment in different situations. It contains alkaline properties that can drastically improve the quality of the soil. It is excellent for plants that do not thrive well enough when planted in soil that is too acidic. When the soil quality is better, plants have a much greater chance of growing and thriving for months and years.
