Woodash and Charcoal for the garden

Winter time is when woodfires are burning in homes for warmth in all but tropical areas around the country.

Or perhaps you’ve been barbecuing or smoking some produce for the dinner table, and have some woodash?


So what do you do with the leftover woodash and bits of charcoal?

Would you be thinking that the woodash and charcoal from the fire can or cannot be used in the garden? 

Let’s find out .

I'm talking with Margaret Mossakowska of 


It turns out the woodash and charcoal are great amendments for your soil in the garden.

Charcoal are the black bits left over when the fire has died down. Essentially, it's the wood that hasn't been fully combusted.

Woodash is alkaline, so it’s great for those plants, such as from the onion family but not for Azaleas, Camellias, Rhododendrons and other acid loving plants.

Charcoal, on the other hand, is great for increasing the water holding capacity of your soil, and potting mix, plus it’s a home for microbes and fungi.

  • You can put your crushed charcoal in the worm farm, but not too much, otherwise the worms will be dessicated. 

Margaret suggests making a liquid slurry of the woodash before adding only a small amount.
