I have heard of the rusty nails thing-----They provide Iron--Dah! NOT acid????

The blue in Hydrangeas comes from more acid in the soil. You have to add it--by some of those acid-type fertilizers. However--Aluminum Sulphate gives them the boost they need for having blue flowers. It may not happen in a year--but if you keep at it--they WILL all be blue!

AS ALWAYS.............patience is a virtue--when it comes to gardening....

I have been giving my bush some of the same. Will see next year!

It is neat to see that some of the blooms are blue--and some are pink---right next to each other. I guess it has to do with where the roots get their nutrients from. Soils DO vary!
