Hydrangea lovers - I bought some Aluminum Sulfate to add to my Hydrangeas - has anyone done this before?

How much per plant and how long does it take to get blue flowers?

It depends on your beginning soil pH.. if you know that, it's easier to offer an opinion.





I'd start out at a minimal rate.. look at the directions on the package for guidelines. If the package calls for 2 lbs, use 1 and see what happens.. you can always ad more, but you can't take it back out.





good luck!
