Found this on the internet:

# Coffee grounds
Sprinkle used coffee grounds around the base of your plants. Use a
fork to stir them into the top layer of soil to add minerals and
fluff. Cooled, brewed coffee (no cream, please!) also works. If you
like your coffee strong, you might want to dilute it first.
# Herbal and black teas
Loose tea or tea bag innards also enhance soil.

Well, they won't do any harm. Tea-leaves are rich in nitrogen.but I
don't know about coffee -- not so, I'd guess. Like all these things,
they work better if composted first.
