I have just bought a 40l bag of compost.

On the bag it says "With added John Innes"; surely that is a meaningless
statement.

I suppose it is in one way. John Innes is really a formulation based on
loam (cut turf, stack in a pile and let rot), sand or grit, peat and a
nutrient formula based on growth stage. I have always found it a bit
heavy. I find peat 'light' so I suppose if I was buying peat and it said
it had added JI i would be expecting a heavier peat mix. If you are into
this then you should be mixing you own devilish concoction. oh by the
way Which has again given Bribery and Quackery there top mark for own
brand compost, do not buy anything else from there though, go to an
independant nursery.
