Egg Shells and Coffee Grounds

[Baseman]

Hi my well knowledgeable fellow gardeners. For our veggie garden we use egg shells and coffee grounds in the soil to get way larger and tastier veggies. Would this also work for our plant of choice?

We dump egg shells and coffee grounds in the compost, it's a great additive. The shells are a calcium source, I think if ground up they might help, but I've never used em directly into my soil.
