How do I neutralize the acidity of used coffee grounds for use as fertilizer?
I've recently tried mixing the used coffee grounds in baking soda, and I'm seeing a very visible chemical reaction. I haven't tried putting it in the ground yet though.

Sorry I've been asleep at the wheel for this community.
Anyway, there is a lot of good info here in the advice you already got.
Coffee grounds aren't acidic, and their pHs are typically 6-7 which is fine. pH usually doesn't start becoming an issue until it approaches 5.
Further, grounds have a great C:N ratio, which means they will decompose relatively fast in the soil, and won't tie up N like other amendments do.
Thanks
