This eggshell tea recipe for plants is proven in the lab test, and it works! Learn everything about it in this informative article.
Eggs are useful for you and Eggshells–for the garden, you may know it already. But if you’re not convinced yet, this eggshell tea therapy for plants will convince you for sure.
The eggshells you often throw away are a rich source of calcium and contain 2.2 grams of calcium in the form of calcium carbonate. This is double the amount of calcium an adult human being needs per day.
According to the document published on the Florida University extension website, eggshell also contains other vital nutrients that plant needs. More specifically, 0.3% Phosphorus, 0.3% 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 the Department Of Agronomy & Soils, Auburn University here suggests that very finely crushed eggshells are a 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.
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, the 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 Potassium.
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 got acidic or neutral soil, but you can also use it if you’ve got alkaline soil as the plants’ ability to absorb calcium doesn’t depend on the pH level.
Calcium is essential 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 the regulation of water and improves the plant’s ability to face temperature changes.
You’ll need 10-20 clean and dry eggshells. The quantity of eggshells depends on how strong the 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 around the base of the plant.
- 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 of interval.
- You can also use hard-boiled eggshell water. Two cups of this water per plant is appropriate.
