Default Barrier in ground to ward off tree root invasion

My very large plum tree is north of my tomato plot and the branches
overhang the northern most tomato plants (the trench for the tomatoes
runs north and south). Even if and when I trim the tree boughs (so
sunlight isn't intercepted), the roots invade the root space of the
northern most 1-2 tomato plants unless I insert barriers to keep the
plum tree roots out. Unless I block tree root access, the northern-most
tomato plant or two are pretty scrawny. Last year, the barrier was
fairly effective, it will be less so this year because the thin veneer
plywood material is decomposing in spite of the wood preservative I
applied when inserted last year.

I'm looking for a material I can use for a root barrier that will last a
few years, maybe last indefinitely. Can I pick up something at Home
Depot or Orchard Supply Hardware that I can maybe cut into pieces with a
jigsaw and use for a root barrier that will last a while?

The trench I dig for my tomatoes is generally about 2 feet deep, because
once I get to that depth (I virtually always do this some time in March)
the trench has standing water when I get to about 2 feet. The soil is
pretty heavily clay, so I work in loads of compost when I refill the
trench, which I make myself. The barriers I've been putting in are about
2 feet (maybe a bit more) from top to bottom.

I might remove the tree, but of course that's a BIG job. Suggestions
appreciated!

Dig another trench and pour concrete with rebar or the reinforcement
mesh.

Consider a _ Bamboo Rhizome Root Barrier_ *

"ProPlas® Bamboo Barrier Film has proven to be an effective material
to prevent the unwanted spread of bamboo."

At least 40 mil.

Perhaps even a pond liner would work.

What about a sheet of acrylic? I use one as a cover on a small pond,
and it's sturdy enough to hold up to being picked up and put back on
every day, and having raccoons sitting on it every night. Look for a
sheet that's thick enough that it won't bend and snap easily. Bonus -
it's lightweight and easy to handle.

We had a similar issue with neighbors' roots invading. We used a
scrap piece of metal siding cut with tin snips into a rectangle, and
buried on long edge just below ground level. Worked for the couple of
years it was in place before we moved, probably will continue to work
for years.

Wondering if the paint/rust that might develop off sheet steel would
be harmful to the tomatoes? probably no more so than any preservative
that would come your plywood.

There is always "food grade" paint.

I have a roll or "root barrier" material that is about 2 feet wide and maybe
1/32" thick plastic that would work well. So it is available somewhere. Maybe a
nursery? You could use plastic or fiberglass roofing material (corrugated
roofing?)

This looks very interesting. It's expensive, though. If bought at this
link, the minimum is 2' x 25' of 40mm. As it happens, I also have a
problem with bamboo from the neighbor's hard, but I've just lived with
the problem for many years. It would be a ton of work to install a
barrier at the property line to keep out the bamboo roots. I don't let
any of that bamboo get anywhere above ground, but there's no keeping the
roots from invading. Unless, I install a root barrier.

In fact I only need a maximum of 10' of the root barrier to take care of
the tomato vs plum tree problem. I figure I can probably score 10' of
this or similar (they say it's polyetheylene) locally (I'm in Berkeley),
or close to it,.

I actually have a sheet of aluminum, it being a sign I found. It would
undoubtedly work, but I'd have to cut it (I think it's bigger than 2'
wide), but it's not enough. I figure I need around 20 square feet. Well,
at least 12.

I was thinking some kind of plastic, but plastic sheeting sounds like it
might work. As long as it doesn't break or crack, that is.

Good time of year to call a place that installs ponds. That black
rubber pond-liner stuff is pretty much indestructible.

Scraps might be available. A 2 foot wide strip would be useless to a
pond install, but should suit you fine.

Dig a trench- tack a strip of this stuff to a 2x4- suspend into
trench- fill trench- remove 2x4- forgettaboutit.

Another option is to root prune the plum tree, on one side. Cut the
root back a few feet...

I have a pear tree with roots under a section of lawn turf. I sucks
the water from the turf and leaves the grass dry. I'm about to sever
a few roots :-/
