We are redoing the end of the garden, and right at the end will be some
gravel of some sort, then a flower bed in front of the fence. We want some
edging stones (they generally seem to be 600mmx150x50) to seperate the
flower bed from the gravel, and was wondering the best way of laying these.
The flower bed will probably be a couple of inches above the gravel. Do they
really need to be set on a concrete base (the soil is quite a heavy clay
type) ? Any tips gladly received :-)
If you just lay them in a groove between the soil and gravel, they will
eventually fall towards the gravel but will be easily straightened when that
happens. If you want a proper job that will last for a long time bed them in
plenty of concrete.
Dig a channel for the edging stones, but a little deeper to accomodate the
concrete mix. (You can buy bags of dry ready-mixed concrete from any DIY
store). Pour it (dry) along the bottom of the channel, then place your
edgings into it, tapping each one down with a heavy implement of some sort.
Firm the concrete mix around the stones with your foot or whatever, then
cover the concrete with your gravel on one side, and soil on the other.
Moisture in the ground will set the concrete, or you can speed it along by
watering it yourself.
See the one at the link above I did the other week, since filled one
side with 20mm limestone and backfilled with soil the other, probably
a bit over engineered but spent a bit more time haunching them so I
don't have to even straighten them. :-)
Put slabs straight onto the soil as it's pretty firm/sandstone under
the topsoil then built up either side with a mix of ballast and
