Hi,

Does anyone have any ideas of cost effective garden edges and retaining
walls?

Retaining walls? Try genuine railway sleepers. No other wood outlasts
them.

I've also used them as garden edging up to three deep/high. overlap nds
and pin with steel reo rod throught them. Hint, get a tripled geared
drill to the do job.


I've just been googling around for railway sleepers. I found them at
Nuway, works out approximately $50/sqm which is better than most other
products except treated pines, but I can't see treated pine being healthy
for a veggie garden.

I was hoping to find a cheaper solution but I'm beginning to think one
doesn't exist.

of course it does. use 2nd hand corrugated roofing! (you should be able to
get this for free, but failing that, it won't cost much). use an angle
grinder to cut it to the right height. i hope i am not being patronising in
saying the ripples should be vertical. also, it should keep snails out as
they can't get over a sharp ridge like you will have on the top.

railway sleepers look awfully nice but they are a bit pricey.

nb it is my assumption you're making veggie beds or something. if you want
it for terrace for a sloped area or something like that, you might want to
track down some stone. if you have some friends who live somewhere stony you
should again be able to get them for free.
