Hydrangea lovers - I bought some Aluminum Sulfate to add to my Hydrangeas - has anyone done this before?
Question:How much per plant and how long does it take to get blue flowers?
Answers:
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!
