Don’t throw out those eggshells. Wash and add to your worm composter or use them with your houseplants or in the garden as a fertilizer supplement.
Egg shells will add small amounts of calcium, potassium, a bit of sodium, but not enough to harm the plants, phosphorous and magnesium. They don’t provide all the nutrients a plant needs but could be used as a supplement to your regular fertilizing regime.
Jeff Gillman, Professor and author of several books including The Truth about Garden Remedies suggests using shells from 4 to 5 eggs per plant. Mix them in the garden soil or potting mix prior to planting.
The water used to boil eggs could also be used as a liquid fertilizer for plants. Just let it cool and apply about 2 cups per plant.
Though only providing small amounts of nutrients, both methods keep the egg shells out of the garbage.
