Eggshells and coffee grounds
Hello there, I generate a lot of both of these and so would like to combine them to use them as a stand-alone fertilizer (I give my other kitchen waste to a local pig owner). However, I haven't seen an exact "recipe".
Can anyone tell me how much powdered eggshell I should mix into my grounds to generate a PH neutral fertilizer?
Anything else I should beware of, in terms of balance?
Thanks so much
