If it was on the surface, yes. But there is a lot of salt underneath
Cheshire, that has not leached in millions of years. I could very
easily believe that many such deposits are mixtures of sand and salt,
and that there are places where salty sand is an accessible mineral
(and not near a current seashore).

Some sand comes straight out of the sea.

In Barnstaple there is (or was for a long time) a sand dredger that went
out into the estuary at lowish tide, somehow gobbled up a sandbank, then
waited for the rising tide to float it off and back up the estuary to
unload.

Dunno what they do with the sand, but I assume they had to wash it,
whatever. (There always seems to be plenty of sand left...)

Obvious, when using sand for seriously sensitive plants (e.g. orchids
or carnivorous ones), it should be well washed. Most plants don't
mind a trace, and quite a lot can handle actively salty soil if they
are soaked when they are watered.


Many of the British wild orchids don't mind quite a lot of salt. Links I
know on the west coast of the Isle of Lewis (regularly doused in heavy
sea spray) are thick with Orchis mascula; Spiranthes romanzofficiana
Subsp. stricta; Dactylorhiza incarnata s/s coccinia; D purpurella; D
Kerryensis; D maculata s/s ericetorum; D fuchsii s/s hebridensis and
others I haven't identified.

One was rather like D ericatorum in form, but the flowers were a
transparent dull orange, and the leaves were low and more-or-less
horizontal like a stripey butterwort. I took a photo of it, but the
light was dreadful, and the next day I couldn't find it again.

That salt in Cheshire has been there for a very long time, isn't very
close to the surface, and is, IIRC, sandwiched between two impervious
layers of rock.

So much sand lies at the surface that no-one is going to mine the stuff,
anyway.

I can't think of anywhere where salt is mined mixed with sand - though
I'm not saying it doesn't happen. The salt in Cheshire is more-or-less
rock, and riddled with tunnels and galleries. I've always meant to visit
the salt museum when I've been in Northwich: I shall one day - my
brother and his family live near there. (And there's lots of surface
sand there too - his village is Sandiway.)

I'll have to go salt prospecting next time I go to Wortham Ling. (About
ten miles away) According to my uncle, who had (probably) the oldest
house in Suffolk on the Ling, that was shore in Roman times, navigable
to there by longboats in the Viking era, though now the nearby River
Waveney isn't tidal to anywhere near there.

Hello Nick

NM When laid down, sea sand would contain salt, but almost all

NM salty sand in the UK, but it will not be sold unwashed by
NM respectable builders' merchants, as the salt interferes with
NM cement and other uses and salty sand does not meet the
NM relevant standards.

But that does assume you bought it from a builders' merchants.

Anyway, wondering way off topic now. OP's sand would've been washed
adequately by being left outside for three years.

I have some builders' sand hanging around in my yard, and I was going to use

My dad however has advised me not to, he says that this sand contains lots
of chemicals which won't do plants any good, because it is building sand.

The sand has been outside in the rain for at least 3 years - does anyone
know if my dad's correct about this, and if so, whether the rain would have
washed the sand clean by now?

Even if it is full of chemicals, if I just use it for an inch-thick layer of
drainage material at the bottom of each pot, would it be OK?

Thanks in anticipation!

It is much better to use horticultural grit as it will not contain huge amounts
of lime. I don't think builders sand contains chemicals but you should be aware
of the ph (acidity) level of the sand. Some plants tolerate high lime level
whereas others will not.

Most builders' sand is silica, and should have no pH value at all as it
is to all intents and purposes, insoluble.

I suppose there is a possibility of some sand from local non-commercial
sources containing limestone, and/or oxides of iron.

Some beach sands can't be relied on either: for instance, there is a
beach on Skye which is made up almost entirely of coral fragments.

Generally though, you can be pretty sure that sharp sand can be added to
any (rooting) medium without it altering the pH.

For quite some time I used to fetch buckets of medium grit from just
above the tidemarks area of the beach, strew it down my sloping path and
leave a hosepipe running at the top end. Then later I mixed it with
compost and peat and dug it into some borders. Also used it for potting.
No harm to plants was noticed.
However, I once got some sacks full of the old straw bedding used for
deep litter on shed floors for fattening cows, and used that as compost.
After its use it had been stacked five years. The particular border it
was dug into promptly decided to do very poorly for a year or three.
I reached the conclusion that it was the funny feed and hormones and
chemics fed to the static cows which "done the damage".

sea and river sources, so if former it would surely have traces of
salt in it?

But I must admit, I've never licked it so can't say.

The tens of thousands of years that's been there, any salt would have
been leached out, whatever the source.


If it was on the surface, yes. But there is a lot of salt underneath
Cheshire, that has not leached in millions of years.


Probably only in places where the geological structure is such as to protect
it from mobile ground water.

I could very
easily believe that many such deposits are mixtures of sand and salt,
and that there are places where salty sand is an accessible mineral
(and not near a current seashore).

For quite some time I used to fetch buckets of medium grit from just
above the tidemarks area of the beach, strew it down my sloping path and
leave a hosepipe running at the top end. Then later I mixed it with
compost and peat and dug it into some borders. Also used it for potting.
No harm to plants was noticed.
However, I once got some sacks full of the old straw bedding used for
deep litter on shed floors for fattening cows, and used that as compost.
After its use it had been stacked five years. The particular border it
was dug into promptly decided to do very poorly for a year or three.
I reached the conclusion that it was the funny feed and hormones and
chemics fed to the static cows which "done the damage".

Hello Nick

NM As Cormaic pointed out, builders' sand has not had salt in
NM it for many decades - at least not if bought from an even
NM half-respectable person.

They don't wash it at the quarry, and that's where I get mine from.
I'm a bit hazy about the geology side - I guess sand comes from both
sea and river sources, so if former it would surely have traces of
salt in it?

But I must admit, I've never licked it so can't say.

For what it's worth, - I live near northside Morecambe bay and near my
house and three-quarters of a miles from the beach was a massive
sand-hill and the sand was used for building most of my town for
hundreds, - probably thousands of years. It is now gone, being worked
out.
I would assume that during all those many years the rains would have
filtered the salt down to the water table.
Are their any experts on the thread to give an opinion?.


Most of the drinking water in the west of the Netherlands is pumped
from under the coastal sand dunes. It is fresh, not salt water.

Most interesting and informative. Thank you.

If it was just stacked and not composted, it would rob the soil of
nitrogen while it decayed. There's the possibility too, that if it was
some time ago, the feed had contained an antibiotic, and this was
killing the soil bacteria.

Thank you Mr. Rusty.
Yes!, Good thinking!. I go for the antibiotic approach now you mention
it. The borders have recovered now, but six apple bushes I had grafted
on dwarf rootstock gradually failed with canker etc. Mind you, I am up
the N'West on the tip of the Furness peninsular and when I see those
lovely apples from warmer climes I think I am on a bum steer here,
climate-wise, though my pears, plums and blackberries flourish.
On another tack , some time ago I was offered a small stack of
well-rotted hay from a silo. I rang the Min of Ag & Fish and they said
it was just inert matter and could be used but the result would not be
encouraging, so I abandoned the idea. A farmer friend I was visiting
was making up a silo load and he was putting very dilute treacle into
it. I don't know whether it was for to add a bit of taste or to assist
the composting.
