Banana Peel Liquid Fertilizer [Disadvantages]

Banana Peel Liquid Fertilizer [Disadvantages]

Short Answer: While banana peel liquid fertilizer is a popular organic option among gardeners, it’s important to be aware of its disadvantages. Firstly, it can attract unwanted pests, such as fruit flies and ants, which may harm other plants in the vicinity. Additionally, this fertilizer lacks certain essential nutrients like nitrogen, phosphorus, and potassium, which are critical for the balanced growth of plants. Overuse of banana peel fertilizer can also lead to an imbalance in soil pH, potentially making the soil too acidic for some plants. Lastly, the preparation process is time-consuming and requires careful attention to avoid fermentation or mold growth, which can be detrimental to plant health.

Perhaps you’ve just had a banana for breakfast, or maybe you’ve made some banana bread and now you’re left with the peels. Although the skin of bananas is edible, you might not be interested in trying the banana peel bacon recipe that went viral in 21.

Did you know that you can use the outer covering of banana peels as fertilizer for your houseplants? It is believed that soaking the peels in water or burying pieces of them in the soil can provide the necessary nutrients for your plants to grow. However, these methods are not the best option. In this text, you will learn why and what to do instead.

Banana Peels for Plants

Banana peels contain essential nutrients such as potassium and phosphorous that are generally present in fertilizers. However, as over 80% of the peel is water, the amount of nutrients they contain in comparison to regular fertilizers is very low. So, whether fresh or dried, soaking banana peels won’t make a significant difference in adding nutrients to the water.

Burying a banana peel in your potting soil also adds nutrients. However, the peels will break down so slowly that they likely won’t provide adequate nutrients when your plants need them. Another downside to banana peels as fertilizer is that rotting organic matter can attract pests such as fruit flies, fungus gnats, and cockroaches.

While you’re better off using a store-bought fertilizer for your houseplants, you can still put banana peels to use in your garden. Toss the peels into your compost bin like other fruit or food scraps. They’ll decompose without attracting pests to your houseplants and help make rich compost you can add to your garden.

Use a commercially packaged fertilizer to add more nutrients to keep your houseplants happy. Look for a houseplant fertilizer with balanced nutrients (equal nitrogen, phosphorous, and potassium). These will add more nutrients and work quicker than using banana peel as fertilizer, even if you soak it or dry it first. Plus, you’ll know exactly what you’re adding to your soil when you follow the label directions.
