Hi Donna,

Why do you need pond liner? The water will need an escape point or you could
end up with a stagnant swamp that wont grow anything worth having.

I suggest you purchase some scaffolding boards - look on ebay or google -
they come in lengths up to 13 feet long x 9" wide x 1 and a 1/2 inch thick
for around £10 a board.
Cut to size, nail or screw together to form a
rectangle which fits the space you wish to use, place where you want the
raised bed and fill with good compost - I'd suggest a blend of 1 large bag
of multi compost, 1 bag of sharp sand and 1 bag of well rotted horse manure
if you can get it.

That should grow almost anything you wish.

Hope this helps.............good luck

Alan

Good afternoon all...

I have been looking around online for advise on raised beds but have not
really found the answers I have been looking for. I was wondering if
people could give me some advise on what materials to use and not use etc.

At the moment a couple of ideas I am looking into are either a premoulded
plastic raised bed on top of a pond liner which is sitting on top of
paving slabs with a gap between for water to flow out of... Or to make it
out of wood on top of the pond liner.

Any pointers or advise would be appreciated

Thanks in advance
Donna
