Eggshells and Coffee Grounds Fertilizer

Eggshells and used coffee grounds make the best, AND FREE, fertilizer for plants and herbs. Some of you might have heard about using coffee grounds…but eggshells? Yes. But why? Well, the used coffee grounds is a source of nitrogen, and the eggshells is a source of calcium – which together make the perfect fertilizer. Here’s how to make it:

After you brew a pot or cup of coffee, let the coffee grounds cool and dry, and place the coffee grounds in a container and cover it. If you’re like me, and you have Keurig that makes one cup at time, you simply keep each of the KCups in a container and open them when you’re ready to use.

Cut a slit through the top of the KCup and peel it back. Scoop out the coffee grounds with a spoon into a container, and cover them.

Then, when you use eggs, rinse the shells and put them in a microwave safe bowl. Microwave them on high for 2 minutes. Let them cool, then place them in a blender or a bullet blender, and blend them into almost a powder for 30 seconds. If you don’t have a blender, you can put the shells in a plastic bag. Take the air out of the bag and seal it. Then crush the shells by rolling a rolling pin or a can over the bag.

Add the crushed or powder shells to the coffee grounds and mix. And that’s it. You have fertilizer. Cover them until you’re ready to use. They will keep for at least a week, but I’m not sure after that because I have a lot of herb plants and I use all my fertilizer weekly.

Once or twice a week you can spoon 1-2 tablespoons of the fertilizer over the dirt of your plants or herbs, and water the plants as normal. You’ll see the results pretty soon after you start this. Happy plants makes me a happy girl!
