Eggshells can be a great addition to worm composting because they are rich in calcium, which is an essential nutrient for worms. The calcium in the eggshells can help to balance the pH of the compost and make it more alkaline, which is ideal for the worms, especially if they are overfed. Additionally, the calcium in the eggshells can help to strengthen the worms’ exoskeletons, which can make them more resistant to disease and parasites.
Another benefit of adding eggshells to worm composting is that they can help to aerate the compost. Eggshells are very porous, and when they are crushed and added to the compost, they create tiny pockets of air which can help to improve the oxygenation of the compost. This is important for the worms, as they need oxygen to survive.
Eggshells can also help to improve the structure of the compost. When they are crushed and added to the compost, they create a gritty texture that can help to break up clumps of organic material and make the compost more friable. This can make it easier for the worms to move through the compost and break down the organic material.
Make sure to crush the eggshells before adding them to the compost, as whole eggshells can take a long time to break down and may not be very palatable for the worms. Additionally, eggshells should be added in small amounts and mixed well with other organic materials.
Overall, adding eggshells to worm composting can provide many benefits, including providing essential calcium for worms, balance the pH, improving the structure and aeration of the compost!
