Egg shells are a great source of calcium for tomatoes and peppers. I put a handful in the hole with the plants when setting them out. It helps to prevent blossom rot.
Using a rolling pin is an easy way to crush the egg shells. Put them in a Ziploc bag and roll until they are fine; another good use for Ziploc bags you have washed to reuse again.
I have been using a blender to crush the shells. Your way is much better, and with less mess.
Thank you
