How to nourish your plants with eggshells

It’s no secret that plants need nutrients to grow. But did you know that you can help give them a boost with something you probably have lying around your kitchen? Eggshells are an excellent source of calcium, and they can really help improve the health of your plants.

Here’s how to get started using eggshells as plant food.

1. Collect Your Eggshells

The first step is simple. Start saving your eggshells. You can wash them off and let them air dry, or you can put them straight into the oven on a low heat to sterilize them. Just make sure they’re nice and clean before you move on to the next step.

2. Prepare the Eggshells

Once your eggshells are dry, it’s time to prepare them for use. You’ll want to powders the shells by either putting them in a blender or food processor, or by smashing them with a rolling pin.

3. Sprinkle the Eggshells

Once they’re in powder form, sprinkle them around the base of your plants. You can also add eggshell powder to your compost pile to give all of your plants a calcium boost.
