How To Use Eggshells In Houseplants: A Natural Fertilizer Guide

Reading Time: 5 minutes

Houseplants have become an integral part of modern home decor, offering both aesthetic appeal and health benefits. But did you know that over 60% of houseplant enthusiasts are constantly seeking natural fertilizers to boost their plant’s growth? Enter the humble eggshell. How To Use Eggshells In Houseplants is not just an old gardener’s tale; it’s a sustainable and effective method backed by science. In this guide, we’ll delve deep into the benefits of eggshells and how they can be a game-changer for your indoor greenery.

The Science Behind Eggshells and Plants

Did you know that the average eggshell is about 95% calcium carbonate? It’s true! This makes eggshells a treasure trove of calcium, a nutrient that’s essential for plants. But why exactly do plants need calcium?

Well, calcium plays a pivotal role in cell wall structure, ensuring that plants stand tall and proud. Without adequate calcium, plants can exhibit distorted growth and even become more susceptible to diseases. But that’s not all. Eggshells also have a secret weapon: their pH-balancing properties. Many houseplants prefer slightly acidic to neutral pH levels. Over time, soil can become too acidic, and that’s where eggshells come in. By adding crushed eggshells to your potting mix, you can help balance the soil’s pH, ensuring your plants remain in their comfort zone.

Preparing Eggshells for Houseplants

Alright, so you’re sold on the idea of using eggshells for your houseplants. But how do you go from a breakfast omelet to a natural fertilizer? Let’s break it down.

First, you’ll want to clean those eggshells. No one, especially not your plants, wants remnants of your breakfast. Simply rinse them under cold water to remove any egg residue. Next, it’s drying time. Spread the shells on a baking sheet and let them air dry. If you’re in a hurry, you can pop them in the oven for about 10 minutes at a low temperature.

Once they’re dry, it’s time to grind. Using a mortar and pestle or a coffee grinder, pulverize the eggshells into a fine powder. This makes it easier for the plants to absorb the calcium.

Lastly, store your eggshell powder in an airtight container. It’ll keep for months, ensuring you always have a natural fertilizer on hand.
