Science Buddies: "Ask an Expert"

I'm Starting a science fair project on how Acidity of soil affects the color of Hydrangeas. I need to find background information. Does anyone recommend any trustworthy sites I can use to look stuff up? Thanks!

Hi there,

A quick Google search for "soil acidity effects on hydrangeas" turned up several interesting sites. I would start by reading through them, and keeping an eye out for citations (references to publications) in the process.

Good luck!
