Using charcoal

Does anyone have information on using charcoal as a soil conditioner?The charcoal has come from bonfires ,used to clear mostly hazel and hawthorn shrubs .I have extremely heavy neutral ph soil and am mostly growing vegetables on it.

  • hello reg,

    i have been saving charcoal from my wood stove to use mixed in compost for my house plants.

    1.put the charcoal in a strong bucket and soak it in a either worm/comfrey or nettle "tea" for a week or 2.

    2.pour off any tea that remains, then leave charcoal to dry out.

    3.once dry, pound the charcoal (in the bucket) into a powder and add to compost.

    the charcoal will slowly release nutrients into the compost.



    it is also possible to use a product called biochar which comes in big bags.

    here's a link you might find interesting.

    I remember reading that it's pretty useful stuff when mixed with soil and is/was widely used around the world, especially in ancient times.  Google "charcoal soil conditioner" and "Terra Preta" for some interesting reading.

    A trowel in the hand is worth a thousand lost under a bush.
  • Are there any plants that particularly benefit from using Charcoal?
