Can banana peel be used as fertilizer if it is soaked in water? Garden art experts tell you the truth: less fruits than imagined

People who often slide short films may have recently seen a trick for garden art: soak banana peels in water, and then put this "self-made banana water" on indoor plants. The number says that soaking banana peels in water can release nutrients (such as drills and vitamin C). Compared to fertilizers soaking in water, it is beneficial to your plant growth. But does this really work?

"Life Leader" Masa. Stewart's website MarthaStewart.com pointed out that there is no discussion yet. Bananas are rich in debris, and humans can directly eat bananas for absorption because this is our way of digestion; but plants need to be decomposed by other organisms to a small extent before they can dissolve and allow the roots to absorb. Cut the banana peels into pieces, soak them in water for two to three days and then filter out the liquid, which may release less nutrients than online rumor.

Luke, a soil fertility expert at North Carolina State University Gatiboni said that if you mix banana peels with water for a few days, you can only release a small amount of nutrients. Because it takes time for the decomposition of microorganisms, you need to wait until these materials are "corrosive" so that nutrients will be released. Microorganisms in the soil are the key to this process, which break down organic carbon links and release nutrients. The nutritional value of banana peel water is questionable, and it is rare to study whether it is beneficial to plants. Brooke Edmunds, an Oregon State University garden artist, said there is no research that defines what the ingredients of banana peel water are. "Will the dessert be poured into the water from the peel? How ripe is the banana skin (cyan, yellow, brown, completely brown)? What else will be poured into the water except the dessert?" These are all very unknowns.

In general, the seemingly convenient banana peel water may be far worse than the old method: banana peel compost, which has been proven to promote plant growth. Composting banana peels has a more direct benefit for plants than making banana water, allowing microorganisms and detritivores (such as earthworms) to do their work and break down organic matter in banana peels. Gatiponi said at least some of the organic compounds during the composting process will be broken down by the microorganisms to release nutrients that can be used directly by the plants.

If you still like the idea of ​​"liquid fertilizer", you can try to make your own composting soup, that is, soak the finished compost soil in water to extract the compost nutrients and microorganisms, which can be used in a few days; the most convenient and effective method is to spend money to buy liquid and solid commercial fertilizers on the market directly.
