What makes a long life trellis? Metal? Wood? Beams?
I live in a pretty dry climate, 5A zone.
We're putting in the garden, and I want to make a wall of trellis for
whatever we want to plant on it. I just wanted to do this once, so was
looking for long lasting suggestions.
Someone up the road from me advertised for some well drilling pipe, and
sucker rods for fences. Is that any good? I'm a retired welder, so if the
cost is okay .......?
Are creosoted railroad ties any good? We want the wall to block vision, but
also to put some grapes, berries, cukes, and other good trellis growers, and
rotate them around.
For extremely long life, metal.
I have two towers made from copper pipe (in my ornamental gardens) and
several moveable trellises** in the vegetable garden framed with thin-wall
galvanized conduit and one made from natural gas pipe (heavy). The
garden trellises have webbing made from "tomato cage" fence wire, which
has had to be replaced once. If I'd used concrete reinforcing wire it would
likely not have needed replacing yet.
These have all lasted for many years, while some decorative PVC and
treated-wood tellises rapidly declined.
**These have extended "legs" which are slipped into larger diameter tubing
which has been sunk into the ground.
A lot will depend on what you want it to hold, and how you want it
to look. For small diameter stuff, probably non-corroding metal
-- copper, aluminum, galvanized steel. For heavier stuff (wisteria),
thick pieced of rot resistant wood are good -- cedar, cyprus -- but
For plant cages to hold annual vegetables, I use reinforcing mesh.
It works very well, but isn't very pretty. After about a year it
is dark rust colored. I kind of like it, though I suspect my
neighbors aren't as pleased. The oldest I have are about 5 years.
I can't see any reason that they won't last another 10.
Creosote is a carcinogen, so lots of people avoid it. If you don't
care, it is also an irritant. I've never had a problem, but some
people get rashes.
Personally, I haven't seen a source for used ties for over 15 years.

If the food the trellis grows is the most important aspect, then metal
or PVC supporting a lattice of of wires, or wire fencing would probably
give you the most longevity. If you wanted something more decorative,
then I would suggest a wooden frame.
