How much of it do you need? You should be able to get it at a farm supply place.

I believe you need Aluminum Sulphate for acid loving plants which is readily available from nurseies etc,made by 'SoGreen'..
Not sure what 'ammonium' is but it sounds nasty.

lots of people say don't buy Aluminum Sulfate, Aluminum Sulfate is not a fertilizer, it will lower soil's ph only, buy ammonium sulfate instead, that's why I'm looking for ammonium sulfate.

Ammonium sulphate is a fast acting source of Nitrogen......probably best used sparingly in most cases. It is not touted as a changer of pH, but chemically speaking one could anticipate some little change.

Aluminum sulfate is used to lower pH, but is not a very nice plant additive....it can damage the root systems of many plants.....especially rhododendrons. It would seem to be a "cosmetic" additive to manipulate the colours of some Hydrangeas. "Give the people what they want", being the credo!! The plants seem to be secondary.

Ammonium Sulphate should be readily available at any place that sells fertilizers. If you can't find it at Rona or the like try a farm supply place.

thank you,

I can't find it anywhere, HD, RONA, Walmart, even biggest nursery in Ontario.

Where can I find the farm supply list near Toronto?

How big an area do you need to cover? If it's just a couple of plants why not get some Garden Sulphur and work that in around the plants?

I had Sulphur already, I think it will change the soil PH, not a fertilizer.

Yes, it will change the soil pH. It will also allow the plants to take up more nutrients from the soil so although technically not a fertilizer it will help.
