Yes, I do add it to compost also. And ditto on the spent tea bags...I'm a tea drinker and DH drinks coffee. And it really does increase the earthworms after you dig it into the soil for a while! Earthworms are soil-builders, which are really needed on my place! Other than caliche, rocks and limestone, the yard is mostly just a bit of soil I've brought in and put on top of everythig that was there before. Caliche will kill many kinds of plants if their roots get to it. One reason I like those great Texas Hill Country natives...many of them tolerate my original soil.
