I have read somewhere's, about what you put in your compost...that it usually ends up being
ALKALINE...meaning, even though you put a ton of stuff in, ie; leaves...the process of breaking down the "stuff" turns alkaline...
Here's a excerpt from University of Minnesota Extension Service;
"The pH of most yard waste composts is usually between 7.0 and 8.0. This slightly alkaline pH of compost should not pose any problems when diluted by mixing into the soil and, in fact, is beneficial to plants growing
on acid soils. Because of the alkaline pH, yard waste composts may not be suited for use on acid-loving plants
such as azaleas and blueberries."
I just recently read this, in a few places..
I don't really remember if I recall reading about coffee grounds...*it was mainly chopped up leaves I remember reading*
But I would whole heartedly aggree with Peppereater, about using as a mulch...
Great on those Azalea's and Blueberry bushes..
Anything acid loving...
I think if there were ever tooo much in the compost is when there's not enough "brown" in
the compost pile for the coffee grounds to work on.
Starbucks has a program called Grounds for Gardeners where you can get 5 pound bags of grounds.
I realllllllllllly wish I had a Starbucks around me, I'd be in 7th heaven....
