I have access to the local Starbucks' daily grounds. Can there be too much of a good thing? I toss it in the beds and in the compost. I just wonder in the winter when things aren't growing if I should continue.
Coffee Grounds
Good question. I know that coffee grounds add some nitrogen, so that might suggest that too much during the winter might encourage winter weeds. You could compost it and save it for late winter.
If you have freezer space it lasts a long time there. I can only get grounds when I go to San Antonio, so I collect them any time I can get them and put them in the freezer. the worms are really supposed to like them, and worms in the compost pile is a good thing. If they don't get eaten til spring that probably wouldn't matter.
I dunno about adding them directly during the winter. But I have tons of leaves in December and never have enough greens to heat them up in the compost. The grounds really help a lot.
So are coffee grounds considered the "green matter" of compost?
They can be "a" green, sure. I have tons of brown leaves and never have enough nitrogen to get the pile hot enough. The coffee grounds help. Dry molasses helps too, but it's not a green.
