sulpher tonic

I got some sulphur recently to dust cut plant tissue against fungal attack and I see it says it can made into a solution with water to increase soil acidity. I wonder if I might give the blue hydrangeas a go, unfortunately there is no indication on the container as to what ratio of sulphur to water to use, anyone any suggestions?

    Verdun is right, best to test the pH level first. It's very difficult to lower the pH in a soil that is naturally very alkaline. To keep it low, that is. Anything you do might have a short-term impact but the effect will pass, particularly if you use anything water-based, because it will leach out very quickly.

    So, I assume, Verdun, that you put vinegar on your chips before putting them in the plants.?;)
