The Hot Water Trick
Many seasoned gardeners soak crushed eggshells in hot water before using them—and here’s why:
-
Removes residue: Hot water helps strip away any remaining proteins or fats.
-
Kills germs: Boiling or steeping helps eliminate bacteria or mold.
-
Releases minerals: Heat encourages the calcium and other minerals to leach into the water, creating a gentle, natural liquid fertilizer.
Once cooled, use this “eggshell tea” to water your houseplants or garden beds. It’s an easy, sustainable way to boost growth without synthetic chemicals.
How to Use Eggshell Water
-
Steep crushed eggshells in a pot of just-boiled water
-
Let the mixture sit for 12–24 hours
-
Strain, then use the mineral-rich water to irrigate your plants
-
Store any leftovers in a sealed container for up to a week
A Few Cautions
-
Don’t use too many shells in one spot—they can raise the pH and make the soil too alkaline.
-
Always clean and dry them properly to prevent pests or disease.
-
Avoid sharp shell pieces in areas where pets dig or walk.
Final Thoughts
Eggshells may seem insignificant, but in the garden, they’re a low-cost powerhouse. Whether crushed into compost or steeped into calcium-rich water, they help plants thrive naturally. So next time you’re about to toss those shells, think again—your plants will thank you.
