If you’ve ever tossed banana peels into the compost and thought, “There’s got to be more I can do with this,” you’re absolutely right. Banana peel tea is one of my favorite garden hacks—simple, sustainable, and surprisingly effective. It’s a gentle, natural fertilizer that gives your plants a nice little potassium kick without overdoing it. Plus, it’s a great way to reuse kitchen scraps without attracting every critter in the county (I’ve learned that lesson the hard way!).
Let’s walk through how to make it, when to use it, and which plants will thank you the most.
🍌 What Is Banana Peel Tea?
Banana peel tea is exactly what it sounds like—a water-based infusion made by soaking banana peels, allowing key nutrients like potassium, phosphorus, calcium, and magnesium to leach into the liquid. These nutrients help with everything from flowering and fruiting to root strength and overall resilience.
Think of it as a vitamin water for your plants.
📋 How to Make Banana Peel Tea
You don’t need any fancy tools or special steps. Just do this:

Instructions:
- Chop the banana peels into 1- to 2-inch pieces (optional, but speeds things up).
- Place the peels in your jar or bucket.
- Cover with water.
- Let sit for 2–4 days, loosely covered to prevent mosquitoes.
- Strain out the peels (toss them in the compost).
- Use the banana peel tea to water the base of your plants.
👉 Optional Add-In: A teaspoon of unsulfured molasses or a splash of fish emulsion (like this organic one) can enhance the microbial activity and nutrient profile.
✅ When and How to Use Banana Peel Tea
Best Use Cases:
- As a gentle midseason boost
- During flowering and fruiting stages
- For stressed or recently transplanted plants
Ideal Frequency:

🌿 Plants That Love Banana Peel Tea
| Plant Type | Benefit Received |
|---|---|
| Tomatoes & Peppers | Boosts fruit production |
| Roses | Encourages lush blooms |
| Squash & Cucumbers | Supports flower-to-fruit success |
| Houseplants | Gentle, all-purpose nourishment |
| Leafy Greens | Use sparingly—focus on other fertilizers |
👉 Avoid using it on acid-loving plants like blueberries unless you balance it with an acidic amendment.
🌼 Bonus Tip: Make a Soaking Bucket for Seedlings
For extra tender plants or new transplants, mix 1 part banana peel tea to 2 parts water and use it to soak the root ball before planting. It’s like a spa treatment for your starts!
🧃 Storage & Shelf Life
Banana peel tea is best used fresh, but it can be stored in the fridge for up to 5 days. If it starts to smell funky or moldy, toss it out and make a new batch. This isn’t something you want fermenting too long on the counter.
🌎 Compost the Leftovers
Once you strain your tea, don’t waste the peels—toss them into your compost pile or blend them into your next compost tea batch.

🐝 Add a Pollinator-Friendly Twist
Banana peel tea won’t attract pollinators directly, but healthier blooms mean more nectar and pollen. Pair this tea with pollinator-attracting herbs like borage or basil (yes, basil!) for a thriving garden ecosystem.
