Your descriuption is completely wrong for this product! It sounds like the description for a hose!

Yes, this looks like the wrong info for this product. The product is great, but it is for Hydrangea flowers, this is not a garden tool.

Will this turn pink hydrangeas blue?

I used it late winter early spring and every flower is now blue-purple. I just noticed in mid July pink flowers are coming again so I will add some more

Is this good for bigleaf hydrangeas?

I guess I don’t Know the difference. But I would expect it to be good for hydrangeas in general🤷🏼♀️ Sorry I can’t be of more help to a fellow gardner

Silly question, when it suggests 1 tablespoon per gallon of water or table per gallon of root ball?

It means to use 1 tablespoon per gallon of water to use watering around the root ball area.
