Using ash in the garden – our top 5

Before we start, Jon Butterworth at Arada stoves reminds us to store our ashes away from the elements in order to preserve their beneficial water-soluble minerals that they could quickly lose in the event of rain.

“Embers can stay hot for days, so make sure your wood ash is completely cool before using it in your garden or home,” he adds.

And a safety advice from us: If you empty your ashes into a container, make sure that it is heat-resistant and not made of plastic.

1. Put ashes in compost to help the plants

Perhaps the most significant, but surprising, benefit of recycling leftover ash is in your compost heap.

Yes, “adding layers of ash to your compost pile will help break down the organic compounds and speed up the composting process,” said co-founder and design director of WOOD STEEL, Alex Waugh. He goes on to say that ashes also help keep odor down and control the number of insects they attract, especially in warmer weather.

“When you use your ashes in your compost heap, always make sure that the wood you burn doesn’t contain any chemicals such as preservatives, paints, or varnishes. We recommend using only dry, seasoned firewood for our fireplaces and fireplaces, ”adds Alex.

2. Is ash good for the ground? Yes it is

Ash is a natural source of potassium and trace elements and can correct acidic soils because it has a liming effect.

“Wood ash is about 70% calcium carbonate, so it gives the same result as lime, but faster because the particle size is much smaller,” adds Alex.

In addition to the horticultural advantages, we can also repel pests with our wood ash.

“Wood ash can also be used to ward off pests such as snails and ants. Sprinkle a small amount or wrestle around susceptible plants and reapply as rain can wash away the ashes and render them ineffective, ”shares Alex. This is further emphasized by Jon, who also suggests stopping snails by “creating a circle of ashes around plants they love to feast on”.

4. Create a chicken dust bath using ashes

After the fun of a garden party draws to a close, there is one more tedious task to complete and that is cleaning the grill. Like us, Jon doesn’t particularly like cleaning up, but he has a tip that will make the process smoother.

“Mix up a thick paste of ash and water and apply it liberally to your grids and the inside of the grill. The ash and water mix with the grease left over from the cooking process, creating a kind of natural soap that will help you clean up in no time, ”explains Jon.
