If it's available to you, straw or spent mushroom compost is good. Some
places might make a small charge for delivering.

Thanks. I'll keep an eye out.

Any advice appreciated
As you have sandy/stony soil, I do not understand why you need to
buy sharp sand to make up your growing medium. Why not get twice
as much decent compost or manure, and mix your current garden soil
with that? If you don't have enough composted material in your
soil, you'll be
forever watering if we have a dry summer.

Maybe I have the wrong impression of the conditions in your
garden.. but sandy/stony soil sounds the perfect growing medium
for lots of annuals - most don't need a rich soil. I'd just keep
adding plenty of organic matter to the existing soil.

Composted bark, other composted matter, John Innes 3. Any general
purpose compost.

Thanks for replying
It looks as though the latter consists of:

7 Loam
3 Peat
2 Sand


to which

0.6kg ground limestone
3.6kg hoof and horn meal
3.6kg superphosphate
1.8kg potassium sulphate

is added per cubic metre

Just because you want to grow annuals it doesn't mean that you have
to go with poor soil. If you use rich soil the annuals will still
grow well, and you won't have to add fertilisers for a year or two.

It also says, "nutrients are typically sufficient for 1-2 months of
growing, after which time additional proprietary feed should be
given". Doesn't sound very long does it? I imagine "topsoil" and
"loam" are pretty much the same thing?

It doesn't sound very long, but they are probably erring on the side of
caution. I would be most surprised if you didn't get a good display of
annuals without additional feeding. Remember too that hoof and horn meal is
effectively a "slow-release" fertiliser, as it takes time to break down in
the soil. Salts like Potassium sulphate are very soluble in water and will
get quickly washed out of sandy soil. Soils containing clay and humus hang
on to soluble material much better.

I would agree with you that topsoil and loam are pretty much the same thing.

Thanks. Now I know what the basic ingredients are I can hopefully just
add what I think I'm short of :-)

Are your plants not growing normally, What is the pH content of your
soil.?
If it is not growing normally, then put a Rusty nail
5inches away dig a hole 3inches place the nail and cover spring a
little water, this will raise the iron content from 0.04 to 0.07 and
the problem will be solved. Further questions I am an organic gardener

If you buy a Ph meterjust be carefull. check that it is reading OK, I
bought one a few weeks ago, I was supprised to find the field which
hadnt seen any lime for 3 years was giving me a ph reading of 7.5 to 8
and according to it Vinegar was extremly Alkaline, I complained to the
firm importing them and they sent me another , same results, I had to
reverse the wires to get an accurate reading
A lot of these things are mass produced in china ........I say no
more, the old Ph testing kit is a safer bet for small tests.
