What are the benefits of wood ashes on the lawn?

Be aware that the ashes of hardwoods are generally richer than those of softwoods. Indeed, they contain a lot of calcium, which makes it an excellent limestone amendment capable of replacing lime to fight against soil acidity. In addition, because of their very high potash content, wood ashes constitute a concentrated potash fertilizer very favorable to the production of flowers, fruits or vegetables. Similarly, they contain a lot of silica, magnesium, the main constituent of plant chlorophyll, but little phosphorus.

However, given the high levels of calcium and potash, ash should be added in moderate amounts. Indeed, an excess could cause a chemical imbalance in the soil and poor plant nutrition. Excess potash, for example, results in poor assimilation of magnesium and other essential elements. Excess lime causes a blockage of essential trace elements. In addition, 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 ground destroys the structure of the earth by asphyxiating it. They are good for the garden, but in limited quantities: 70 g to 100 g per m2 and per year. Spread them in the winter once and everything will be fine on the most beautiful of lawns.

Where to put wood ashes in the garden?

First, allow the wood ashes to cool for several days until they are thoroughly cold. To store them, we advise you to put them in a large closed metal container. Also, always use gloves, as wood ashes are caustic. Whatever your use, note that you have to scrape the soil a little 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 ashes so as not to interfere with the proper aeration of your compost. As we suggested above, too much wood ash in the compost could slow bacterial activity and thus slow down the decomposition of your compost. Nothing very encouraging for your future lawn…

As you know, wood ashes on the lawn also serve to enrich the soil. They favor on the one hand a better drainage, and on the other hand encourage the microbial life like that of the earthworms. The important thing is not to have a heavy hand! Finally, you can use wood ash to control pests. Be sure to spread them correctly, in dry weather, on the ground around your vegetables for example. They should effectively scare away slugs and snails. On the other hand, if your ground is wet by the rain, go your way, the ashes will no longer have any interest.

They will act in particular on the moss, which they will dry out effectively and durably. Please note that there are a few precautions to take.

Finally, a little reminder of the basics of weeding for those who are embarking on the exercise for the first time:

  • Avoid weeding in the middle of the day, especially during hot weather
