How can I soften my water?
 
Hi All,
I seem to have a number of plants that prefer pure water (as opposed to our
very hard tap water).
I only have a very small garden and nowhere to easily catch rainwater.
Is there anything I can do to treat the tapwater so as to remove the salts
that my plants don't like.

The sensitive plants are a Nepanthes & several Orchids.
Thanks
Matt

Use the rainwater from your house roof, you can get an adapter which fits
onto your downspout and directs the rainwater into a water butt....the ones
I've seen don't allow the butt to overflow and re-directs surplus water into
your drains.

He mentioned collecting rainwater, so I assume his rainwater is softer than
his tapwater

I wasn't sure if he realised just how acid rainwater can be in some
places.


I think you will find that rainwater is always soft, as hardness comes from
the (calcium) rocks it may filter through. However acidity is another thing
and you are correct to suggest that acidity (or lack of it) depends on the
atmosphere that the rain has passed through. Tap water can be any
combination of these depending where your water comes from, what the
atmosphere was doing at the time the rain fell from the sky and how it was
treated by the water company.
Hardness can be temporary or permanent. I used to keep tropical fish and
found acidity easy to determine with a ph kit, hardness on the other hand
is a complicated beggar to test for.
Your water company will tell you if you ask.

Hi All,
I'm not sure how acid my rain / tapwater is, but I do know my tapwater is
very hard.
I don't have anywhere I can collect rainwater as there's no space to put a
water butt near my house (unfortunately).
just wondered what my optios are with the stuff coming out of the tap!
Cheers,
Matt

Catch the mel****er when you next defrost the freezer. Or defrost the
freezer whenever you want to water the plants.

keith ;-\) 17-07-2005 07:45 PM

You could buy a water softener, or leave the tap water to stand in
buckets/watering cans for a few days which reduces some of the shit in the
water we recieve.

could care either way, how can dissolved calcium and magnesium be of any

Posting etiquette aside, anyone know how to soften tapwater? ;O)
Defrosting freezer - mine doesn't frost up ever.
Letting tapwater stand - doesn't actually soften it.
Brittas filter - apparently does sod all as far as plants are concerned.
Iron water - never heard of it - what is it, and where can it be purchased.
I wonder if it's the same as car battery water. I had a pitcher plant that I
watered with this a few years ago. Maybe I should look into that again. I
thought it was rather expensive for water, and I wasn't entirely sure if it
was suitable...

Distilled water and from the chemist. Washing soda is used to soften water
but whether that is suitable for your purpose, I don't know.
"Washing soda is sodium carbonate.
Adding sodium carbonate to hard water
will precipitate insoluble calcium carbonate or magnesium carbonate.
This is a way of removing permanent hardness from water."

Phil L it really does matter about the water,continues tap water to a

time.For short periods is o.k ,but long term not.

AFAIK, small amounts of dissolved calcium and magnesium aren't
themselves harmful to the majority of plants (or any?). It's the high
pH that often (but not always) accompanies them that renders
insoluble, other important elements (mainly iron and manganese) in the
soil or compost and hence unavailable to certain plants that need more
than other types (ericaceous plants are the obvious example). So the
plant suffers and the foliage usually turns yellow (chlorosis).

Hardness of water is described as either temporary or permanent. Both
types reduce the ability of soap to lather because of the presence of
calcium and magnesium ions in solution. Temporary hardness is caused
by the bicarbonates of calcium and magnesium, and is called temporary
because boiling the water drives off carbon dioxide and allows calcium
or magnesium carbonate to precipitate (e.g. as lime scale), so
allowing the soap to lather more easily. But the pH of the water will
actually rise. Permanent hardness is caused by the sulphates or
chlorides of calcium or magnesium. Boiling will not precipitate them,
but the pH of such water isn't necessarily high anyway.

If in doubt, check the pH of your tap water, that's the key point
here. Use a colour indicator kit obtainable at most garden centres.

Defrosting freezer - mine doesn't frost up ever.
Letting tapwater stand - doesn't actually soften it.
Brittas filter - apparently does sod all as far as plants are concerned.


Actually it replaces calcium ions with sodium, but plants that are
sensitive to excessive dissolved salts will still not like it much. The
salts build up near the surface of the soil as water evaporates forming
a crust.

Iron water - never heard of it - what is it, and where can it be purchased.


Ionised water? Any garage.


De-ionised water - although rainwater is much very cheaper and easily
available with a little effort for watering plants. Not good enough for
car batteries though which can potentially be damaged by even traces of
common salt from sweat (or tapwater).

I wonder if it's the same as car battery water. I had a pitcher plant that I
watered with this a few years ago. Maybe I should look into that again. I
thought it was rather expensive for water, and I wasn't entirely sure if it
was suitable...


Natural rainwater is perfectly OK. You don't want it too pure either. NB
De-ionised water isn't too good to drink since it may be deionised but
it can still contain organic residues from the exchange column.

Indeed it is. But it will make the water even more alkaline (i.e. it
will raise its pH). This is bad news for plants that can't tolerate a
high pH in their soil, such as ericaceous plants. The water may be
'soft' in terms of soap lather, but it's no good for so-called 'lime
hating plants' (a misnomer if ever there was one).
