Is it OK to put oak sawdust on my garden this fall or spring and till it
in? I heard oak has tannic acid in it. Would that hurt it?
Thanks

You left out a whole lot of information.
WHERE is this garden located?
What sort of soil do you have?
How much sawdust do you contemplate tilling in?

Is your soil managed organically (biologically hyperactive) or chemically
(semi-comatose)?
