old used coffee and tea is good to put in your compost bin or in your
garden...I used to use it mixed with dirt and my earth worms in a large
garbage pail with lid did the trick and with siol on top worked well and the
worms turned it into real good soil and used it mixed with other dirt for
growing veg and tomato plants and pepper plants and added abit of sand too..
It works real good to recycle and starbucks also offers free used coffee
grounds for your garden and they have a brochure about using coffee grounds
for your garden and the benifits...

Works well for rhododendrons and azalea also:
Van Veen Nursery in Portland, Oregon, has been using coffee grinds from
Starbucks Coffee House for about 18 months. They have been very
satisfied with the results. 1) it helps to aerate their clay soil. 2)
slugs don't like to go through. (so you can see we have both mixed in
and put on top.) It does help to make the soil more acidic. But it does
not replace fertilizer.
They suspect that by making the soil more acidic you are actually
helping the uptake of magnesium. This in turn helps iron uptake and that
helps to make the plant green. So really you are starting a process not
fertilizing. Combine the coffee with horse mature and organic mulch and
watch the amount of fertilizer you use decrease dramatically. As for how
we apply it, when the plant is dry and just before it rains we sprinkle
it on and around. The rain takes it from there. Otherwise we incorporate
into the new beds. No exact rate just cover the top and work it in.

I toss my grounds in an old dishwashing powder tub. When the tub is full, I
use it to fill the ruts in the empty field across the road. Is it ok to use
with seedlings in starting planters?
Coffee grounds are quite acidic. Don't get excited when I say that a higher
than normal acidity level in soil may help ward off some diseases FOR A
SHORT TIME, because in the long run, most of the seeds you grow probably
won't like the pH. Or, maybe in the short run. Just don't do it.
If you use the grounds as a contribution to your composting bin they'll help
break down the other elements more quickly (worms love them) and you'll
balance out the ph much better. They'll still be effective for repelling
slugs and they are very beneficial to the soil. We've been doing this in our
garden for quite a few years now and the soil and plants are thriving. You
can use the grounds straight to build rings around plants that are getting
hit by slugs but they work better over the long run as a composting element
and as an amendment with mulch.

"Roasted coffee is fairly acidic, but it appears that
almost all of the acid is water soluble and is extracted
during brewing. Used grounds have essentially neutral pH,
although the coffee beverage produced is rather acidic."
Personally, I've used coffee grounds as both compost
and direct soil amendment. It works well either way.
