What Plants Like Boiled Egg Water?

Plants, like any living organism, need water to survive. However, not all water is created equal, and some types of water may be more beneficial than others for your plants. Boiled egg water is an option that many gardeners swear by, claiming it provides essential nutrients and promotes healthy plant growth.

In this article, we will explore the benefits of boiled egg water for plants and discuss which types of plants are most likely to benefit from this method. We will also provide tips on how to properly prepare and use boiled egg water in your gardening routine.

How Does Boiled Egg Water Benefit Plants?

Nutrient-rich Composition of Boiled Egg Water

Eggshells are primarily composed of calcium carbonate, making them a rich source of calcium for your plants. When you boil eggs, the shells release calcium along with other essential nutrients such as sodium, potassium, nitrogen, and phosphorus.

These nutrients play a vital role in plant growth and development. For example:

  • Sodium: Helps plants regulate their water balance
  • Potassium: Promotes strong root development and overall plant health
  • Nitrogen: Essential for producing chlorophyll (the molecule responsible for photosynthesis)
  • Phosphorus: Promotes flower and fruit production

Effect on Soil pH Levels

The pH level of soil can affect a plant’s ability to absorb nutrients. Generally speaking, most plants thrive in soil that has a slightly acidic pH range between 6.0 – 7.0.

Boiled egg water can have two different effects on soil pH levels depending on the method of preparation:

With Vinegar or Lemon Juice

Some gardeners recommend adding vinegar or lemon juice to the boiling water before adding the eggs. This results in an acidic solution that can lower soil pH levels over time when used regularly.

Acidic soils tend to be more ideal for plants such as blueberries, azaleas, and rhododendrons, which require acidic soil to thrive.

Without Vinegar or Lemon Juice

If you don’t add vinegar or lemon juice during the boiling process, boiled egg water can be slightly alkaline. This can raise soil pH levels over time when used regularly.

Alkaline soils tend to be more ideal for garden vegetables and flowers such as spinach, garlic, and peonies.

Best Practices for Using Boiled Egg Water for Your Plants

Preparing Boiled Egg Water for Plant Use

To prepare boiled egg water for your plants, follow these steps:

  1. Bring a pot of water to a boil.
  2. Add eggs (with or without shells) to the boiling water.
  3. Boil the eggs for 10-12 minutes.
  4. Remove the eggs from the pot and allow them to cool.
  5. Pour the cooled boiled egg water into a container.

Which Plants Benefit from Using Boiled Egg Water?

Boiled egg water can benefit a variety of plants including:

Perennial Flowers

Perennial flowers such as asters and daisies can benefit from additional calcium in the soil provided by boiled eggshells. Calcium promotes strong cell growth and helps maintain plant structure.

Fruit-bearing Trees and Vegetables

Fruit-bearing trees such as apple and pear trees need plenty of potassium during fruit development stages. Vegetables that grow underground (such as potatoes) also require potassium to develop healthy root systems.

Container Gardens

Plants grown in containers generally require more frequent watering – often leading to nutrient depletion in the soil. Adding boiled egg water can help replenish essential nutrients and promote healthy growth.


Houseplants typically grow in less fertile soil than plants grown outdoors. Providing an extra boost of nutrients with boiled egg water can help improve their overall health.

How Often Should You Use Boiled Egg Water?

The frequency of using boiled egg water on your plants depends on various factors such as plant type, climate, and soil type. Generally speaking, it is safe to use boiled egg water once every two weeks during the growing season. However, you should always monitor your plants’ health and adjust accordingly.

Risks Involved with Overusing Boiled Egg Water on Plants

While boiled egg water can provide several benefits to plants, there are potential risks associated with overuse. Too much calcium in the soil can prevent plants from absorbing other essential nutrients such as magnesium and potassium.

It is essential to use boiled egg water sparingly and only when needed.

Other Considerations When Using Boiled Egg Water for Your Plants

Odor of Boiled Egg Water

Boiling eggs can create an unpleasant odor that lingers even after the eggs are removed from the boiling water. While this won’t necessarily harm your plants, some people find the smell unpleasant.

To avoid this issue, consider boiling eggs outside or in a well-ventilated area away from your living space.

Can You Use Already-Peeled Eggs?

Boiling already-peeled eggs won’t provide the same nutrient-rich solution as including shells during boiling. If you have leftover hard-boiled eggs and want to use them for a fertilizer solution instead of eating them directly as food, include some extra calcium-rich ingredients such as bone meal or crushed eggshells.

Potential Harms Caused by Using Uncleaned Eggs

Using uncleaned eggs for boiled egg water is not recommended due to the risk of salmonella bacteria. To ensure proper safety measure before boiling eggs used for fertilization like thoroughly washing them properly before putting them into boiling water.


Boiled egg water can be a beneficial addition to any gardener’s routine if used correctly. It provides valuable nutrients while also improving soil pH levels. However, it is essential to use boiled egg water sparingly and only with the right plants.

By following our recommendations on preparing and using boiled egg water for your plants, you can help ensure healthy plant growth and a bountiful harvest.


  1. Q: Can I use boiled egg water to water my plants? A: Yes, you can! Boiled egg water is an excellent source of nutrients for your plants.
  2. Q: Which plants like boiled egg water the most? A: Tomatoes, peppers, and roses are some of the plants that love boiled egg water.
  3. Q: What makes boiled egg water so good for plants? A: Boiled egg water contains essential nutrients such as calcium and potassium, which are beneficial for plant growth.
