Ugghhh, too much work and potentially harmful to a septic tank.

The Popular Mechanics Home Handyman book series that my folks got me back in the 60s
has a solution that works very well, requires practically no work, is dirt-cheap and
is septic tank friendly.

Get a piece of cheese cloth perhaps 18" square, three wood dowels or something
similar about a yard long, a pound of calcium chloride (concrete antifreeze) and a
pound of copper sulfate (garden supplies).  Copper is death on roots even in small
quantities.  If your area has high humidity, use more copper sulfate and less calcium

Mix the two chemicals, put the mix on the cheese cloth, pick up the corners and make
a hobo-pack-style bundle.  Tie some string around the top.  Use some string to bind
the tops of the three sticks together and spread out the other ends to make a small
tripod.  Tie the bag of chemicals to the sticks so that it hangs down in the center.
Position this assembly over a floor drain or other opening that drains to the sewer.

Calcium chloride is highly hygroscopic.  It will attract enough water from the air to
liquefy itself and the copper sulfate, forming a saturated solution.  The solution
will drip from the bag, a drop every few hours, and enter the drain where the copper
will nuke the tree roots.

How well this works is illustrated by my cabin here.  There's a huge hickory tree,
perhaps 75 ft tall, growing directly over my field line.  Been there for 40+ years.
Never even a hint of root problems or septic system problems.  I started doing this
treatment shortly after we built the place back in the early 70s.  It's so humid here
that I use about a 1:3 mix of CaCl to CuSO4.
