I have just swept my chimney and have a rather large bag of soot.

Soot from burning coal or wood?

Coal soot is likely to have quite high concentrations of heavy metals so
I'd be wary of using it on the veg patch.

Other than that others may have better knowledge, it's mostly carbon so
not exactly a plant nutrient but may help condition the soil.


The idea of soot being good for the garden was an invention by chimney
sweeps to solve their disposal problem.

I'm not so sure. When I was little, there was always a heap of soot
down at the allotments where my father's plots were. I know my father
used it knowledgeably, as did other plot holders. I can't remember
whether it was to help blanch celery, or to deal with fungal diseases,
or something else. It was certainly valued. I wish he were still alive
to ask.
