This easy, eco-friendly method extracts nutrients in a form plants can easily absorb. Follow this step-by-step guide to create your own nutrient-rich fertilizer at home.
Materials You’ll Need
To make banana peel soak fertilizer, gather the following items:
- Banana peels: 2–3 peels, fresh or slightly dried
- Water: 1 liter
- Container: A glass jar, plastic container, or any food-safe vessel with a lid
- Knife or scissors
- Strainer
- Measuring cup (optional)
Step-by-Step Guide to Making Banana Peel Soak Fertilizer
Step 1: Prepare the Banana Peels
Start by rinsing 2–3 fresh banana peels to remove any dirt or pesticide residue. Use a knife or scissors to cut the peels into smaller pieces, about 1–2 inches long. This increases their surface area, helping nutrients release into the water more efficiently.
Step 2: Place the Peels in a Container
Transfer the banana peel pieces into a container, such as a glass jar or plastic tub. Choose one large enough to hold the peels and water with some space for stirring or shaking.
Step 3: Add Water
Pour 1 liter of water into the container, ensuring the peels are fully submerged. You can use either filtered or tap water, depending on what’s available.
Step 4: Soak the Peels
Seal the container with a lid to prevent contamination and odors. Allow the banana peels to soak for 24–48 hours at room temperature. During this time, nutrients like potassium and phosphorus will leach out into the water. Shake or stir the container occasionally to promote even extraction.
Step 5: Strain the Mixture
Once the soaking period is complete, use a strainer to separate the liquid fertilizer from the banana peels. Transfer the liquid to a watering can or spray bottle for easy use.
Bonus Tip: Don’t throw away the leftover peels! Add them to your compost pile or bury them in your garden soil for additional slow-release nutrients.
How to Use Banana Peel Soak Fertilizer
For soil application: Pour the liquid fertilizer directly onto the soil around your plants. Use approximately 1 cup for small plants and 2–3 cups for larger ones, adjusting based on their size and needs.
For foliar spray: Transfer the liquid to a spray bottle and lightly mist it onto the leaves of your plants. This method works particularly well for houseplants and flowering plants.
Frequency: Apply the banana peel soak fertilizer once every 1–2 weeks for optimal results.
Why Use Banana Peel Fertilizer?

Its potassium content promotes strong stems and healthy growth, while phosphorus aids in flowering and root development. Additionally, its gentle formulation ensures it’s safe for most plants.
By following these simple steps, you can create an effective, homemade fertilizer that keeps your plants thriving—naturally and affordably. Give it a try and see the difference in your garden!
