3. How to Prepare and Apply Eggshell Fertilizer
Here’s how you can prepare eggshells to maximize their benefits:
- Clean the Eggshells: Rinse eggshells thoroughly to remove any egg residue, which could attract pests if left on the shells.
- Dry the Eggshells: Place the cleaned shells in a warm area or bake them in the oven at a low temperature for about 10 minutes to dry completely. This makes them easier to crush and reduces any lingering odor.
- Crush or Grind: Once dried, crush the eggshells using a rolling pin, or for a finer texture, grind them in a blender or coffee grinder. The finer the powder, the quicker the calcium will be absorbed by the soil.
- Application: Scatter the crushed eggshells around the base of your plants, particularly those prone to calcium deficiency. Alternatively, mix the eggshell powder directly into your compost or potting soil.
4. Eggshells as a Liquid Calcium Fertilizer
For a quicker calcium boost, you can create an eggshell tea:
- Add about 10-12 eggshells to a large pot of water.
- Boil the mixture for 10-15 minutes, then allow it to cool and steep overnight.
- Strain the liquid and pour it around your plants’ base or use it to water your garden once a week for an immediate calcium boost.
5. Which Plants Benefit Most from Eggshell Fertilizer?
Plants like tomatoes, peppers, eggplants, and other calcium-loving vegetables will thrive with a regular addition of eggshell fertilizer. Leafy greens, fruiting plants, and flowering shrubs can also benefit from the calcium in eggshells, as it supports stronger growth and healthier foliage.
6. Additional Tips for Eggshell Fertilizer Success
- Regular Application: Incorporate eggshells into the soil throughout the growing season for a steady release of calcium.
- Combine with Other Fertilizers: Eggshells are best used alongside other organic fertilizers that provide nitrogen and phosphorus, as they primarily supply calcium.
- Composting: Add eggshells to your compost bin to break down with other organic material. They enrich compost with calcium, supporting plant health when compost is later applied to your garden.
Final Thoughts
Eggshells, as a natural and sustainable option for enriching soil, provide an excellent boost for gardens of all types. By adding this common kitchen waste to your gardening routine, you’re supporting healthier plants, reducing waste, and fostering a more eco-friendly approach to garden care. Embrace the hidden value of eggshells and enjoy the benefits they bring to your green space!
