Very interesting discussion on fertilisers, its a very useful world where 
the likes of Jim Shields cuts to the chase as I had totally forgotten some 
of the terms being used in these posts. Pretty well all plants, whether 
trees in my past career or every genus of alpine or temperate plants require 
N. P. K.along with Trace minerals in minute quantities. Our soil here is 
acidic, very acidic as its derived from glaciated granite debris, generally 
around the pH 4.5 to 5.0 mark. In order to introduce humus as an aid to good 
growth we use composted bark derived from mainly Pine + Spruce with a little 
Birch + Oak but it tends to sequester, lock up, N. so adjustments are made 
to compensate. Obviously readily available fertilisers most probably vary in 
their presentation but in Scotland, Europe generally, the medium of choice 
are slow release granules with varying content of N.P.K. plus trace 
minerals. In addition these are sold with different rates of release, e.g .6 
month, 9 or 18 months. Where we live the use of Bone Meal has its problems, 
Dogs, Foxes. Martens just love to role in it or dig hoping to find THE BONE, 
not very welcome habits so I would suggest some thought, at least we no 
longer have Wolves or Bears to cope with.

Jim's advice recommending checking your soil pH is vital, so too is annual 
and even seasonal precipitation. Soil type can have material effects on 
rates of fertiliser leaching which needs to be taken account of. Getting any 
soil tested for pH should be straight forward as every garden centre here 
sells cheap kits to do just that.
Our additional problem in terms of soil fertiliser is the total lack of 
available free Lime here in almost all of the Highlands, fortunately very 
few species of Lilium require readily available Lime and this is provided on 
a localised basis, where needed and always assuming I haven't forgotten.  We 
also use, for seedlings and young bulbs, a balanced soluble fertiliser as 
salts in suspension when watering, however this stops under our conditions, 
partly because at close to 58 degrees North our growing season is 
comparatively short e.g with coastal Pacific USA + Canada and anything later 
than the end of August, as a rule, stops in order to harden off the bulbs, 
of whatever age, otherwise in frozen soil a lot of damage occurs including 
total death despite free draining sandy and gravelly soil.

Jim's analogy with rules of taxonomy and chemistry is well made, the world 
has moved on quite a bit including all measurements being metric.  I think I 
am correct in saying that the USA is now the only country in the world still 
using imperial measurements in terms of volume, weights, heights, diameters, 
distances, temperatures, etc. I have now quite forgotten both how to 
calculate comparisons e.g. Centigrade v. Fahrenheit, its been so long ago, 
not long after WW2 in fact, and like everyone else I don't even try anymore, 
my dithering old brain can't cope nor my memory either. That said, other 
than the US, I think the UK, is the only country left still mucking about in 
yards and miles, causes our European visitors and tourists no end of bother, 
quaint indeed. Our gallons for diesel and petrol are equal to five litres, 
while I think, the US gallon is equal ? roughly to four litres. Some of the 
chemicals refered to in these posts are simply not freely available to the 
gardening + horticultural communities in Europe, what's more the prospect of 
using some of those mentioned, knowing what they are and can do if 
mishandled, frighten the bejisus out of me. Wood ash is fine for the roses 
and fruit bushes, but for bulbs, hardly.

To conclude, one worrying aspect for me is that the new Lily Monograph 
probably won't do very well in the USA as everything is cited in metric, Ho 
Hum!

Happy Easter to one + all. May the frost leave our soil soon please, at c. 
15 cms {6 inches) its a real pain as the days get longer.  Iain
