Now what?

I've always heard rumors that certain plants (blueberries?) are "caffeine freaks" and thrive when coffee grounds are added around them. So last month I started saving all our used coffee grounds and tea leaves in a separate compost bowl.

The bowl is now full and I'm ready to do something with it.

But what? How do coffee and tea grounds work for plants?

I've read a variety of things online, but they seem to contradict. Some say the grounds need to be composted. Others say they should be just added around the plant base without composting. Yet others say to mix the grounds with sawdust (for acid-loving plants) and mulch.

So, since the collective wisdom of my readers far exceeds the wisdom of the internet (wink), what is your experience with using coffee and tea grounds on plants?
