Egg Shells and Coffee Grounds in garden
Are egg shells and coffee grounds really good to mix in your soil? I have been reading that putting crushed egg shells and coffee grounds in your holes when planting vegetables in the garden is really good, is this true? Also, I made a compost tea last summer and still have a 5 gallon bucket of it. It has been sitting covered outside since last summer, would it still be good to use this year or should I make a new one? Thanks for your help. Sharon

Egg shells add calcium and coffee grounds add nitrogen, coffee also acts like a stimulant to plants like it does for people. You can add them to the compost pile or work them directly into the garden.
Compost tea does have a shelf life. This article should help:
