While some sources suggest banana water benefits plants due to its potassium content, there's no scientific evidence supporting its effectiveness as a fertilizer, and it may even harm plants. Using banana peels, however, is a different matter.
The Controversy Surrounding Banana Water for Plants
Many online sources promote using banana water as a plant fertilizer, highlighting the potassium in bananas as beneficial to plant growth. For example, this TikTok video suggests pouring banana water around the base of watermelon plants. Other sources (this Reddit thread, for example) recommend using banana water for outdoor plants.
However, reputable sources like The Spruce and Reader's Digest clearly state that there's no scientific research confirming the benefits of banana water as fertilizer, and it might even be detrimental.
Banana Peels vs. Banana Water: A Crucial Distinction
The confusion likely stems from the difference between using banana peels and banana water. Several sources advocate for using banana peels as fertilizer, either by adding them directly to the soil (Sustainable Holly) or by soaking them in water and using the resulting solution (Quora). The potassium content in the peels is the purported benefit. However, the concentration and potential for unwanted bacterial growth in banana water are not well-understood and might outweigh any benefits.
Best Practices for Fertilizing Watermelon Plants
Focus on proven methods for fertilizing watermelon plants. Using commercially available balanced fertilizers according to package directions is recommended. Always check your soil’s nutrient levels to guide your fertilization strategy. Brown Mamas emphasizes the need for adequate care, especially for fruits like watermelons, including appropriate sunlight and water.
