Peace lilies are known for their white flowers—but getting them to bloom feels like a guessing game. Here is a homemade remedy for you.
What if the secret to a bigger, blooming peace lily was already in your kitchen? Banana peels are packed with nutrients that can support healthier growth and encourage more blooms. You can use them as a liquid fertilizer, powder, or soil amendment to see the difference for yourself.
Banana Peel As Fertilizer For A Bigger Peace Lily Flower
1. What’s Actually in a Banana Peel
People are putting banana peels in their peace lily pots, but why? Banana peels are naturally rich in potassium, a nutrient that plays a key role in flower formation. Adequate potassium helps peace lilies direct more energy toward producing strong stems and larger blooms.
2. Promotes Root Growth
We all know that banana peels are rich in potassium, but they also contain phosphorus, a root-building nutrient. A peace lily with a well-developed root system can draw water and minerals from soil, creating the metabolic surplus the plant needs to fund flowering.
Without adequate phosphorus, roots remain shallow and sparse, the plant lives in a kind of hand-to-mouth nutritional state, and flowering is the first luxury to be cut.
3. Boost Soil Microbial
As banana peels decompose, they feed beneficial microorganisms in the soil. These microbes help break down organic matter into nutrients that your peace lily can use more easily. The first month of peel feeding builds the bacterial population.
The second month sees the fungal network expand. By the third month, the soil itself has changed—it holds water better, drains more cleanly, and the pH sits more consistently in the sweet spot.
How to Use Banana Peels on Your Peace Lily
There are several methods that many gardeners have tried. Here’s what actually works, starting with the easiest.
Method 1: Banana Peel Tea (An Easy Method to Try)
This is the gentlest and most controlled method. It works well if you’re nervous about over-fertilizing or if your peace lily is in a decorative pot without good drainage.
What you do: Collect two or three banana peels and roughly chop them, soak them in a jar or container with about one liter of water, leave the jar somewhere out of direct sunlight for 48 to 72 hours, strain out the solids, and use the amber-colored liquid to water your peace lily once every two to three weeks.
The resulting liquid is mild enough that you’re unlikely to shock the plant, but rich enough in soluble potassium and phosphorus to make a noticeable difference over a few weeks.
Caution: Always water the plant with plain water first, then follow with the peel tea. Never apply any fertilizer—even an organic one—to bone-dry soil. It can stress the roots.
Method 2: Burying Peels Directly in the Soil
This is the slow-release version, and it suits peace lilies in larger pots with room to work with.
Cut the peels into small pieces—roughly an inch or two—and bury them about two inches below the soil surface, along the outer edge of the pot (away from the main root mass).
As the peels break down over two to four weeks, nutrients leach into the surrounding soil. Do not pile peels on top of the soil. They’ll attract fungus gnats and may introduce mold before they can decompose properly.
Method 3: Dried and Powdered Peel
If you have a surplus of peels and some patience, drying and grinding them into a powder gives you a versatile, long-lasting fertiliser you can store and use gradually.
Spread the peels flat on a baking tray and dry them in a low oven (around 60–70°C) for two to three hours, until they’re completely brittle. Grind the dried peels into a coarse powder using a blender or food processor. Sprinkle about a teaspoon of the powder on the soil surface once a month and water it in.
This releases nutrients slowly with each subsequent watering and is particularly useful through the growing season (spring and summer).
Try banana peel fertilizer for yourself and see how your peace lily flowers bloom. Pair this feeding with your daily plant care routine, like proper watering, light, temperature, and repotting. Do let us know in the comments if this kitchen remedy worked for your plant.
