Mulch – How Does It Affect Soil?

Mulching the garden is a very common recommendation. Mulch will reduce the number of weeds and it will hold moisture in the soil but how does mulch affect the quality of soil?

There are lots of claims that mulch improves soil but have you ever seen numbers to validate them? I haven’t either. How exactly does mulch improve soil? It should add organic matter, but how much? It should increase the number of microbes, but is this really true? Unfortunately, almost nobody studies landscapes and gardens because no one will fund the work.

Luckily I was able to find one very good research paper that looked at this exact problem.

Fungi in Wood Chips

This post, Fungi in Wood Chips, was prompted by a picture and discussion on a Facebook group called Australian Native Plant Enthusiasts (ref #3). The discussion was about the harmful fungi that appeared in wood chip mulch used in children’s playgrounds. Off course they posed no real danger–but people were scared. There are a lot of misconceptions about fungi growing in the garden and this post will look at the truth about fungi in wood chips.
