1. Fertilizer: If you want to add extra calcium to your composting, eggshells are the perfect choice for you. They have the ability to decompose very quickly due to their high surface area to volume ratio. There is no need to sterilize or grind them up. Simply throw them on the pile or in the compost bin.
Optionally, you can add your crushed eggshells directly in the bottom of the planting holes during spring.
In winter, you can spread around the eggshells over the land lot where you will plant the following spring. When the ground is warmed up, you can dig the shells in the soil. However, you can also clean and keep them until the upcoming planting season.
Adding extra calcium is especially beneficial for tomatoes and peppers because they are prone to calcium- deficiency.

3. Seed-starter Pots: Due to their quick decomposition ability, eggshells can serve as perfect seed-starter pots. Do the following procedure: when you break the egg to remove the content, make sure you make just a small hole at the pointier end of the shell.

Stop baking when they are completely dry, but not brown on the inside. Next, crumble the eggshells and put them in a feeder or on the ground during spring or summer season.
