You really do not want to place the mulch against the house any more than
you want to place the muclh against the trunk of trees. If you use mulch
near your house you want to make sure that it has composted. Composted
mulch will reduce your chances of getting artillery fungus on your house.
Agian even if the mulch is well composted you don't want to place it against
the trunk of your trees or do you want to pile it against your structure.
Have you ever seen where mulch was piled against a tree trunk and then
removed? Its bleached as well. Most of the time I recommend a mulch that
I deal with. It is composted tree trimming from the chipper, which has
composted for a year or more.
I have a section on mulch in two areas.

Has anyone had issues with mulch eroding their foundation? I have
poured walls and the put dark hardwood mulch against it (for the last
three years). I noticed that the foundation was getting lighter (like
it was bleached) and when I went to investigate the areas that had
mulch against it, would flake and fall off. Fortunately I have caught
in time, but I need to know what mulch is safe, if any, to use by my
house's foundation.

Any advice?
