Nope - have at it.

It will be great lasting mulch. If you're putting it around exiting plants first pile it up like a compost pile and turn it weekly for 3-4 weeks to allow it to partially decompose aerobically. The potential problem is "sour mulch", which is the emission of volatile organic acids (e.g., formic acid) that occurs in the early stages of wood decomposition. It can and does kill plants. See link below for more on sour mulch.

If your wood chip mulch is kept to a reasonable depth, 3 to 4 inches at most, it will not generate enough heat for that pyrolisis to occur. I have seen what the article is about on rare occassions when wood chips are stored in such a way that they can generate quite a bit of heat and are not allowed to cool down before application.

thank you for all of the information!
