When I'm 'building' my compost pile, over a period of about a month or so, I will add several pounds of Starbucks coffee and filters/day . Very high in nitrogen and a little bit of carbon from the filters. My pile is officially 'cooking' but I will still pour coffee grinds on top to get those autumn leaves to decompose.
Coffee nitrogen is good but is acidic and can burn certain plants and trees if applied directly (learned the hard way on my fig tree).
My homemade compost is only one-third of the recipe however. It's probably a bit acidic from all the coffee grounds. I add a high end manufactured compost such as Dr. Earth, worm castings, rock dust (Azomite), fish bone meal, kelp meal, vermiculite and oyster shell flour. Mix that in a wheel-barrow and add to the beds. Wham! My lettuce/spinach bed is sprouting away right now. |
