Eggs are useful for you and Eggshells, for the garden, we already discussed that. If you’re not convinced yet, this eggshell tea therapy for plants will definitely convince you.

Eggshell Nutrition

The eggshells you often throw away are the rich source of calcium and contains 2.2 grams of calcium in the form of calcium carbonate. This is double of the amount of calcium an adult human being needs per day. According to the document published in Florida University extension website, eggshell also contains other important nutrients that plant needs. More specifically, .3% Phosphorus, .3% Magnesium and traces of sodium, potassium, zinc, manganese, iron, and copper.

Crushed Eggshells For Plants

One of the ways is to put whole eggshells directly on top of the soil, or you can lay crushed eggshells. The test report published by Charles C. Mitchell, on behalf of Department Of Agronomy & Soils, Auburn University here suggests that very finely crushed eggshells are more decomposable and effective source of calcium and other trace elements than the coarsely hand crushed shells.

Why Use Eggshell Water

A much better way to provide eggshell benefits to plants is to make eggshell water or tea. This is a quick organic approach to make nutrients available for plants after the application.

The Experiment

Jeff Gillman, the master gardener, former Associate Professor of Horticulture at the University of Minnesota and author of The Truth About Garden Remedies, writes about his experiment, in which he boiled an eggshell in a few cups of distilled water. After boiling, shell remained in that water for 24 hours. He then sent the eggshell water for testing in the lab. The results were surprising, the three elements that increased in low concentrations were Sodium, Phosphorous, and Magnesium. The two other elements that increased in higher concentrations were 4 mg of both Calcium and Pottasium.

You can say 4 mg is a small quantity, but it comes out of just one eggshell, boiling 10 eggshells can definitely increase the concentration of these five elements, which can impact your plant’s growth.

How it Works


This eggshell tea can work as a nice Calcium and Potassium amendment and also helps in raising the soil pH, slightly. Very useful, if you’ve acidic or neutral soil pH but you can also use it if you’ve got an alkaline soil as the plants’ ability to absorb calcium doesn’t depend on the pH level.
Calcium is very important in root development and cures the problem of short roots. It affects the fruit quality. Strengthens the cell wall structure (improvement in cell wall structure increases the plant’s strength). It also helps to fight against diseases and protects the plants from heat stress.
Potassium is the second most significant element that plants require, apart from Nitrogen. It’s known to increase drought tolerance, color, and flavor of fruits, photosynthesis, and stem strength. It helps in regulation of water and improves the plant’s ability to face the changes in temperature.

The Recipe

You’ll need 10-20 clean and dry eggshells, the quantity of eggshells depends on how strong solution you want to make. Boil crushed eggshells in a gallon of water and let them sit for 24 hours. This will give enough time to the plant nutrients available in shells to infuse in the water. After that strain the water and it’s ready to use!

How to Use

Use the eggshell tea in your garden or for your potted plants. Pour this healthy calcium-Potassium supplement directly on the soil. According to Gillman, 4 to 5 eggshells per garden plant is sufficient. For potted plants, reduce this quantity to 2 or 3. Apply this eggshell tea in either one or two weeks interval.
You can also use hard boiled eggshell water. Two cups of this water per plant is appropriate.

  1. Hi There, Into a 1ltr ice-cream container 4 chopped up small pieces plus 9dried crushed egg shells which I soaked into the hot water that almost filled the container for 4 days… It was starting to bubble a little bit then I strained it into a spray bottle.. This I sprayed my plants that were not growing so well… After about 2 weeks these plants were at least twice as big as the others of the same species.
    The left over egg shells and bananas I laid around the base of my roses. All I can say is, all looking good.. It’s sure worth a go. Normally I only use worm tea on all my garden and green is a true grass Green.. Thanks for giving me the inspiration to do my garden I’m 76 and loving it life. hazel

  2. I collect all the shells in a breathable container, like a tough paper bag. A few times a year I grind them to a powder in an old blender from the thrift store, dedicated for the purpose. I sprinkle the powdered shells on the garden, with dirt, compost etc. I barely have time for that, let alone boiling the darn things!
