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'm going to do some no dig garden beds as well as some retaining walls
to make small terraces.

Really depends on look and traffic. I've used carport channelled
roofing, about 1' deep, but you need steps to enter and leave the garden.
