Let’s find out together how to easily use wood ash on the lawn. Don’t thank us, it’s a pleasure!

What are the benefits of wood ashes on the lawn?

Keep in mind that the ashes of hardwoods are generally richer than those of softwoods. In fact, they contain a lot of calcium, which makes them an excellent limestone amendment capable of replacing lime to combat the acidity of the soil. Furthermore, due to their very high potassium content, wood ashes constitute a concentrated potassium fertilizer which is very favorable for the production of flowers, fruits or vegetables. Likewise, they contain a lot of silica, magnesium, the main constituent of vegetable chlorophyll, but little phosphorus.

However, given the high levels of calcium and potash, ash should be added in moderate amounts. An excess, in fact, could cause a chemical imbalance in the soil and poor nutrition of plants. An excess of potassium, for example, results in a poor assimilation of magnesium and other essential elements. The excess of lime causes a blockage of essential trace elements. Furthermore, it could lead to the destruction of soil humus and the release of nitrogen in gaseous form.

In short, wood ash on the surface of the soil destroys the structure of the earth by asphyxiating it. They are good for the garden, but in limited quantities: 70 to 100 g per m2 and per year. Diffuse them in the winter once and all will be well on the most beautiful lawn.

Where to put wood ash in the garden?

First, let the wood ashes cool for several days until they are completely cold. To keep them, we advise you to place them in a large closed metal container. Also, always use gloves, as wood ashes are caustic. Whatever your use, keep in mind that you have to scrape the soil a bit after spreading them. Also, never use them on young plants.

You can use it to make compost. For this, it is advisable to add a thin layer of wood ash so as not to interfere with the correct aeration of the compost. As we have suggested above, too much wood ash in compost could slow down bacterial activity and thus slow down the decomposition of the compost. Nothing very encouraging for your future lawn…

As you know, wood ash on the lawn also serves to enrich the soil. On the one hand they promote better drainage, on the other they promote microbial life such as that of earthworms. The important thing is not to have a heavy hand! Finally, you can use wood ash to control pests. Make sure you spread them correctly, in dry weather, such as on the ground around vegetables. They should effectively scare away slugs and slugs. If, on the other hand, your ground is wet from the rain, go your own way, the ash will no longer be of any interest.
