Mulch to use around trees

[BXMMCC]

Check to see if the Blue spruce is acid-loving. Lots of evergreens are. In that case, pine needles might be best.

In some areas, hardwood mulch can lead to black mold. Once it gets started, it's almost impossible to contain. The state had to move out of and is tearing down the old MVA building not far from me - black mold!

We use stone chips over weed barrier cloth in some spots and pine needles in others around out place.
Yep, the pine needles do a fine job of killing the weeds!

I kinda like the idea of newspaper and pine needles Plus a tall stake by each tree so they remain visible. Pine needles will be acidic so they fit right in with spruce. If you want blue spruce needles put some iron fillings around the tree.

Note: Some hardwood mulch like walnut may not be a good idea.
