Potash on roses - how much to use?

I was convinced by a friendly old chap at a local Open Garden to try Potash on my roses, but now IÂm confused as to how much. Can people advise what they use?

This chap said to use 150g per bush every 3 months: sprinkle it over the ground and water it in well. But when I bought a bag this morning, it says to use just 10g per square metre  thereÂs a bit of a difference there! Another bloke at the nursery said something in the middle  about 50g per bush every month (which adds to the same overall as 150g every 3 months I suppose, but who knows if it is better in little doses or one big hit?)

Ok, IÂm now officially confused. This chap's roses looked BRILLIANT so he must be doing something right, but I don't want to burn the plants - and for all I know, I heard him wrong!

Thanks all ...
