One more point. If the turf is in the drip line of your tree, and your goal
is to preserve tree health - do not dig out the turf. The roots of turf
grow deeper than the non-woody roots of trees. In digging out the turf you
are also digging out your absorbing roots of your tree which facilitate the
absorption of essential elements dissolved in water. Not a good treatment
for the tree.

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.

We would like to apply bark mulch in several areas around our home
where grass currently exists. Is there a need to get rid of the grass
before applying the mulch, either by lifting the sod or laying
cardboard and four inches of soil, as we do when preparing a new bed,
or can we just lay landscape fabric and 2-3 inches of mulch and that
will take care of the grass over time.
thanks
Teresa
