How much is too much coffee grounds in compost

Hmmm...the Cap't will have a good answer, I bet. But I'd think as long as the 'greens & browns' are kept in balance you'll be fine. I put our daily ration in the pile...however much it takes to make 8 cups of coffee.

Most brewed coffee grounds are at a near perfect pH near 6.5 and and almost perfect to use as a soil amendment and balanced protein/nitrogen fertilizer by itself, without being composted first!

I use lots of used coffee grounds around my trees and hedges, and as a pest control around many of my fall/winter crops.

If I collect a lot of extra coffee grounds, I sprinkle it in my compost mounds, making sure to cover it with dry carbon matter, to conserve nitrogen, and induce internal heating and decompostion.

Happy Gardening!

I agree with Captain Compost. Use coffee grounds directly as a fertilizer at 10-20 pounds (dry) per 1,000 square feet. Composting them first is sort of a waste of available protein.
