Great in all situations mentioned tho' piles tend to go moldy.   They
are basically acidic so I wouldn't use them fresh around lime lovers,
but all organic stuff goes neutral when it decomposes, in my
experience (except peat).

I must say I agree with Jim.  All the tested data I've found
indicates that the concentration of caffeine needed to kill slugs is
extraordinarily higher than would be found in coffee grounds - even
espresso.  I've read lots of posts saying they work, but when I've
tried them, I have seen no appreciable reduction in slug damage nor
activity...they're good for the soil, tho'.
