There is nothing wrong with crushing up few eggshells in a planting hole or composting your banana peels. Eventually it all becomes the same stuff for your garden... nutrients. You can, however, speed up the process of taking eggshells and banana peels to workable nutrients for you tomato plants and other vegetables. Dry them and grind them. Create more surface area.
The video will show you the whole process. There is no exact recipe or ratio so don't worry about that. You simply dry out your shells and peels at about 170 degrees and grind them down in a coffee grinder. Add 2 or 3 tablespoons to your planting hole for tomatoes and peppers and you are good to go.
Eggshells bring a great source of calcium to your tomato plants which is a great way to prevent blossom end rot. The browning of the bottoms of tomatoes. Banana peels are a great source of phosphorous and that is one of the three main nutrients needed for thriving vegetable plants. Shells and peels are also a good source of micro-nutrients.
By pulverizing them you create more surface are and with more surface area you have greater microbe and 'break down' activity. The homemade fertilizer will starting breaking down and feeding your plants. Enjoy! You can always ask your neighbors to save you their eggshells.
