Bit confused on the mulching business as it has multiple meanings. The
mulch I've seen around some smaller trees was obviously put there to keep
the rif-raff out of the area. Not to promote growth of the tree. If
"mulch" could do both, great.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding
us that we are not the boss.
