Used coffee grounds are generally better straight on the plants, without composting. I've started several rose bushes off in nothing but pure grounds in place of soil. (Though I did add a dash of plant food.)
If you make toddy, you'll know where how I got that much!
Recipe for Toddy
Ingredients
5Lb Coarse Ground Coffee
5Gal of Water (approx)
Tools
5 Gallon Bucket (with lid)
1 Clean Pillowcase (wash it first if its brand new)
Put the 5lbs of coffee in the pillowcase, and tie it off.
Put the pillowcase in the bucket, and fill to near full with water.
Put a lid on the bucket, and put bucket in fridge.
Soak piilowcase in water for 2 days.
Remove pillowcase and use the grounds for whatever.
Toddy is good for about a week if kept refrigerated.
(Great for basically any cold coffee based drink, extremely heavy caffiene... using decaf coffee ground results in toddy with about the same caffiene as regular coffee brewed in a pot, using regular coffee makes toddy with the caffiene content of Jolt cola. I use it for making coffee based ice creams, and as the basis for my own enery drinks.)
Yes, I got tired of buying energy drinks. I now make my own. I make about 5 gallons at a time. (The recipe just makes toddy, not the full recipe for my drinks.)
