Bury a Raw Egg in a Planter: Here’s the Effect on Your Garden
It sounds strange at first—burying a raw egg in a planter—but this old gardening trick has been used for generations. When done correctly, a raw egg can act as a slow-release natural fertilizer, giving plants a gentle nutrient boost over time. Here’s what really happens in your soil, how to do it safely, and when you should (or shouldn’t) try it.
Why a Raw Egg Can Help Plants
Eggs are rich in nutrients that plants need to grow, especially:
- Calcium (from the shell) – strengthens plant cell walls
- Nitrogen (from the egg white and yolk) – supports leafy growth
- Trace minerals – improve overall soil health
When buried, the egg slowly decomposes, releasing nutrients gradually instead of all at once like synthetic fertilizers.
What Happens After You Bury the Egg
- In the first weeks, the egg remains mostly intact
- Soil microbes break down the shell and contents
- Nutrients slowly seep into the surrounding soil
- Roots absorb calcium and nitrogen as they grow
The result can be stronger stems, greener leaves, and improved flowering, especially for calcium-hungry plants.
Best Plants for This Trick
This method works best for plants that benefit from extra calcium:
- Tomatoes
- Peppers
- Eggplants
- Roses
- Houseplants in large planters
Calcium helps prevent issues like blossom end rot in tomatoes and peppers.
How to Bury a Raw Egg Correctly
- Dig a hole at least 6–8 inches (15–20 cm) deep
- Place one raw egg, uncracked, into the hole
- Cover completely with soil
- Plant above or nearby—not directly on top of the egg
Depth is important to avoid odor and pests.
Important Cautions
- ❌ Do not crack the egg
- ❌ Do not bury too close to the surface
- ❌ Avoid small pots—use medium to large planters only
- ❌ Don’t overdo it (one egg per planter is enough)
If buried too shallow, eggs can smell as they decompose and may attract animals.
Egg vs. Crushed Eggshells
- Raw egg: slow-release nutrients over time
- Crushed shells: mostly calcium, slower benefit
Both are useful, but the raw egg offers a broader nutrient profile.
Is It Better Than Store-Bought Fertilizer?
Not necessarily better—but more natural and gentle. This trick is best used as a supplement, not a replacement, especially for long-growing plants.
The Takeaway
Burying a raw egg in a planter isn’t a myth—it’s a simple, natural way to enrich soil and support healthy plant growth when done properly. Like many old-school gardening tricks, it works best with patience and moderation.
