Yes just putting eggshells in the garden is not a quick return. So try this. It is a practice in Natural Farming!

Here is the video that inspired me. https://www.youtube.com/watch?v=sU5TXvjsTv8
I don't necessarily agree with the video's assertion that a calcium deficiency is always the cause of blossom end rot. I've heard from several master gardeners that it's often caused by a plant's inability to uptake the calcium that is already present in the soil. Take that for what you will, I just thought it was worth mentioning.
Yes, the reason for a deficiency is not always due to a lack of the mineral. If only it was so simple. Calcium issues are typically indoor problems or in plant beds that would naturally reduce the amount of available calcium over time. Often seen where people put in bag soils and those soils become depleted of calcium over time without amendments/inputs.
Have a great day, hope that helps at all or just preaching to the choir for the most part!
