I have been pondering this a lot as we are getting lots of different kinds of mulch
1. From leguminous trees that have lots of green matter still attached, this seems fine for the veges.
2. From hardwood trees like African mahogany which some people say is allopathic.
3. I read some where recent that wood ash should be mixed with vinegar and left for a few days to enhance its qualities
Any comments would be appreciated
