Eggshell water is a fantastic approach to compensate the soil’s deficiency in calcium. Eggshells that have been cooked by boiling release calcium into the water in a soluble form.
Plants can be watered with eggshell water since it contains calcium and amino acids for the plants. Plants utilize calcium to support the structural integrity of their cell walls as well as to strengthen their stems and leaves. Rapid and vigorous plant development is the outcome of providing enough calcium.
In this article, we’ll go over the advantages of applying eggshell water to your plants, how to manufacture your own, and the best application techniques.

What does Egg Shell Water Contain?
Calcium, which is derived from calcium carbonate and makes up the egg’s hard shell, is the primary mineral in an eggshell.
In reality, calcium carbonate is a crystalline type of calcium that is structured in a way that makes the egg layer sturdy enough to safeguard the delicate embryo inside.
Eggshells, snail shells, seashells, and pearls are all made primarily of calcium carbonate, which is a common substance found in rocks as the minerals calcite and aragonite.
In pure water, calcium carbonate has a very low solubility (15 mg/L at 25°C), but when rainwater is saturated with carbon dioxide, more soluble calcium bicarbonate forms, increasing the solubility of calcium carbonate. It is unusual for calcium carbonate to become more soluble as water temperature drops. [Source]
In order to receive the most soluble form of calcium, I do suggest that you grab a container of rainwater before preparing eggshell water for your plant (calcium Bicarbonate).
This is the only method, in my opinion, to make sure that the calcium from the egg is getting into the water.
An great substance for increasing soil pH is calcium carbonate.
In soils with a pH between 5.5 and 6.5, the majority of plants thrive. Some plants, however, prefer a more alkaline soil.
Soils that require an alkalinity boost can be broadcast over and amended with calcium carbonate.

The Egg Shell – Facts!
Additionally, the shell includes a thin outer layer known as the bloom or cuticle, which aids in blocking out dust and pathogens.
Even though eggshells are only 0.3 millimeters thick, they create a highly robust protective coating for the developing embryo inside.
Calcium carbonate makes up the majority of eggshells (CaCO3). 95 percent of the total shell structure is made up of this.
The calcium carbonate’s ability to crystallize is influenced by the remaining portion, which is a combination of protein molecules called osteopontin. The shell structure would be too fragile without the protein.
Because of its semipermeable membrane, its pores allow for the passage of moisture and air.
These two translucent protein membranes are situated in the space between the eggshell and egg white.
When preparing the nutrition water for the plants, these protein membranes disintegrate.
How is Boiled Egg Water Beneficial to Plants? Explained
The egg water contains calcium and proteins, which are advantageous nutrients.
Let’s start by looking at calcium:
Calcium Nutrient:
Calcium must be in a soluble form in order for plants to be able to use it. This means that it must be completely dissolved in water in order for roots to absorb it and carry it to the areas of the plant where it is required.
A secondary nutrient that is essential to crop development is calcium. All plants require a significant amount of it for the synthesis of cell walls and membranes.
When compared to the key macronutrient micronutrients Nitrogen (N), Phosphorus (P), and Potassium (K), as well as the variety of other micronutrients that plants require for optimal growth and development, I say secondary because it is a micronutrient.
Plants utilize calcium to support the structural integrity of their cell walls as well as to strengthen their stems and leaves. Similar to how it strengthens bone structure in humans, it serves this purpose in animals.
Other than for cell growth, calcium is necessary for plants to respond to stress by conveying signals of stress via calcium ions Ca+ throughout the plant.
Additionally, a lot of calcium speeds up cell division and growth, which promotes the quick development of stems, leaves, and flowers.
The portion of the plant that has to respond then processes these signals.
An excellent illustration of this is when you observe leaves curling inward on a hot day to stop moisture loss or when the stomata close and open to control the water in the plant when the environment changes.
Plants contain calcium:
- bolsters cell walls
- helps keep pH levels stable
- energizes enzymes
- enables better water penetration
- increases disease resistance
Protein:
While some protein types serve as storage for glucose and other nutrients, others work as enzymes that start metabolic events inside of cells.
From the amino acids in nitrogen fertilizer, plants make proteins.
The amino acids cause the channels via which calcium can be absorbed to open up in the root cells.
The flimsy membrane that tightly encircles the interior of the eggshell is where the protein in eggshells is found.
These proteins disintegrate when placed in hot water and get into the water.
The amino acids required for the plant’s metabolic processes can be provided by adding this water to the soil.
How Do You Know Your Plant is Calcium Deficient?
Tomato blossom end rot is a typical example of calcium insufficiency.
Initial signs of calcium insufficiency include localized tissue necrosis that stunts plant growth and causes young leaves to curl or have necrotic leaf margins, and terminal buds and root tips to eventually die. New growth and tissues that are expanding quickly on the plant are typically the first to be harmed. [Source]
If potassium, magnesium, or sodium levels are excessively high or if calcium levels in the fertilizer solution are less than 40–60 ppm, a calcium deficit may result.
Due to their increased solubility and competition for available space, these bigger salts will readily dissolve in water before the calcium does due to their high concentrations of sodium, potassium, and magnesium.
Therefore, the water that the root draws up from the earth would contain less calcium.
How to Make Egg Shell Water for Plants
This is done to extract the protein and calcium from the eggshell. After cooking, you might want to collect a few eggshells for a stronger remedy. (the more the better)
- Gently wash eight to twelve eggshells under running water.
- Put the cleaned shells in a pot to cook.
- Turn the heat to medium (350 oF)
- Every 10 to 15 minutes, stir
- Boil for 30 to 45 minutes.
- Save the water for your plants and strain out the residue that collects on top of it.
When eggshells are boiled, the water they produce is more nutrient-rich than if they were broken up and given to the soil.
This is due to the calcium and amino acids from the eggshells leaching into the water due to the heat from boiling.
How to Apply Boiled Egg water to Plants
All plants can benefit from boiling egg water because it contains essential nutrients for plant growth.
Nevertheless, the application technique would change depending on the kind of plant it was being treated to.
Depending on the type of plant, eggshell water can be administered using any of the three techniques.
| Plant Class | Watering Technique |
|---|---|
| Succulents | Misting |
| House Plants | Top watering, bottom watering, and misting |
| plants in gardens | Top irrigation and spraying of the soil. |
Using rice Water with Succulents
Succulents can be watered with boiled egg water while also receiving essential nutrients.
Succulents need more dry, aerated soil, so the water needs to be squeezed so that it may be sprayed on the soil.
When watering succulents as usual, you can spritz them with an egg water solution. At any given time, succulents only need a modest amount of water and nutrients.
Eggshell water is a reliable way to mist succulents to give them the calcium they require without overwatering them and generating problems related to overwatered soil.
How to Mist Succulents with eggshell Water
- Any spray bottle from a household can be used, provided it has been well cleaned.
- The water in the eggshell should be thin enough so that it can be sprayed out of the spray bottle.
- Fill the spray bottle with water.
- The plant should be misted or sprayed on both the top and bottom of the leaves.
- Spray some of the rice water on the topsoil as well.
To help the plant absorb moisture and nutrients, misting should be done in the early morning or late at night. Additionally, this keeps the liquid from being too rapidly dried off by the sun’s heat.
Bottom Watering with Boiled Egg Water
Another technique to provide plants access to the calcium and proteins in the egg is to water them from the bottom using eggshell water.
By watering from the bottom, the soil will be able to absorb the water completely without becoming overwatered.
By doing this, the entire mass of the plant roots will have access to the proteins and calcium that the eggshell water supplies.
How to bottom water with boiled egg water
- Use a little, flat container that is two inches bigger than the planter.
- Put the plant inside the pot.
- Water should be added until the plant pot’s side is 1 to 1 inches high with water.
- 15 to 20 minutes should be given for the plant to soak in the water.
- Stick your finger into the soil after some time has elapsed to check for wetness.
- You can take out the plant as soon as you notice that the soil is moist but not soggy.
- Place the plant so that any extra water can drain away.

Plants that like boiled egg water
Plants that prefer boiled egg water prefer a more alkaline soil with a pH between 7.5 and 8.0.
This is primarily because the pH of the soil is slightly raised by the calcium carbonate. You should exercise caution not to add too much, though.
- Angus the Blue
- Daylilies (Hemerocallis spp.)
- Delphinium
- Spring lilies
- Azalea
- Lavender (Lavandula spp.)
- Clematis
- Photinia
The reasonably priced Trazon Soil 3-in-1 Meter can be used to measure the soil’s pH and moisture content. It checks the pH as well as the amount of moisture and light. Clicking here will take you there!
What are the Precautions When using Egg Water
- If you give your plants too much egg water, the pH of the soil could rise above 8.0.Higher soil alkalinity levels can inhibit plants from absorbing iron, which can cause young leaves to chlorose due to a decrease in the amount of chlorophyll.
- To avoid killing the bacteria in the soil and harming the plant, you should always make sure the water is at room temperature or ambient when using egg water in the soil.
- The soil can benefit from the addition of boiled egg water, but caution must be used when watering because it is simple to overwater the area, which can cause root rot and yellowing of the plant’s leaves.
To make sure the plant receives the proper quantity of water for optimum growth, I advise using the bottom watering approach.
Using Eggshells Directly in the Soil
You can still use the remaining portion of the shell after the calcium and proteins have been extracted by boiling the shells.
This is due to the fact that some calcium won’t leach into the water. Shells will fully vanish if that occurs.
You may now grind the leftover shells in a blender after allowing them to cool and dry.
The resulting ground-up shells can now be used to supplement the soil’s calcium content.
The eggshell powder will serve as a calcium source for the plants that releases calcium slowly.
By doing this, you ensure that you are utilizing every feature that the shell has to offer.
The Takeaway
A cheap and environmentally acceptable method of giving plants calcium and amino acids is by using eggshell water.
It is easily made by boiling leftover eggshells and filtering the solids out.
Plants need calcium to reinforce their cell walls, which in turn makes their stems and leaves more rigid. Additionally, it aids plants in relaying stress signals to locations requiring a reaction or action.
Either misting bottom watering or top watering techniques can be used to apply eggshell water to plants.
Knowing how useful eggshells may be for your plants, you can now store them.
FAQ
What are crushed eggshells good for in the garden?
Fertilizer. Above: Ground eggshells add calcium to the soil when they are tilled into it. The most important nutrients for good growth are nitrogen, phosphorus, and potassium, but calcium is also necessary to create strong “bones,” or the cell walls of a plant.
Is eggshell water good for all plants?
Eggshells are a great plant fertilizer. To develop wholesome and robust, plants need calcium from the soil. Eggshells also include other nutrients that the soil of your plants needs, including more than 90% calcium carbonate. So give this a try if you wish to cure your plants.
What plants benefit from eggshell water?
Shell fertilizer is particularly beneficial for plants like tomatoes, peppers, and eggplants. The additional calcium will assist in avoiding blossom-end rot. In addition to being calcium-rich, broccoli, cauliflower, Swiss chard, spinach, and amaranth may use more calcium from eggshells.
