There are many popular gardening trends that take off through the internet, ranging from fun and interesting ways to improve your garden to some more bizarre trends. If you’ve heard about the recent trend of using banana water for plants, you might wonder which category this trend falls into. What is banana water, and why are people giving it to their plants? Does it actually benefit your plants at all, or are there better alternatives? We’ll answer all your questions in this simple guide to using banana water for plants.

What is banana water?

Banana water is exactly what it sounds like — banana peels and water. The process is simple and requires little prep. Take your banana peels and cut them into smaller pieces. Soak them in water for a few days, then use the water to feed your plants. The idea behind this trend is that the nutrients in banana peels will come out of the banana peels and into the water.

When you use the water for your plants, it’s supposed to serve as a fast-acting fertilizer, delivering vital potassium and vitamins to your plants. Gardeners who enjoy this trend claim it’s a simple and organic way to fertilize plants, while others say it is ineffective and potentially harmful. So what’s the truth?

Does banana water benefit plants?

Banana water is not particularly beneficial for plants. While it’s true that bananas and banana peels contain many important nutrients that can benefit plants, most of these nutrients will remain in the peel. A tiny amount of the nutrients will end up in the water, but the amount is small enough that it won’t impact your plant’s overall health.

If you’d like to see this for yourself, here’s a fun experiment you can run at home. All you need is banana peels, water, and three home soil test kits. You can find soil test kits in many gardening stores and online, and while they can’t measure the exact amount of nutrients in the soil, they can measure the range your soil falls into. Measure the soil levels before adding the banana water, directly after adding the banana water, and finally, a day or two after adding the banana water. You should see no change between the three tests.

Does banana water have drawbacks?

Banana water for plants may not be beneficial, but does that mean it’s harmful? Well, not necessarily, but it can be in some cases. On its own, using banana water for plants is just a slightly more complicated method for watering your garden. If you take care not to overwater your plants, then there’s no real harm to it.

However, there is one potential drawback to banana water. Anytime food decomposes, it can become a breeding ground for pests, bacteria, and mold. Placing the banana peels in water doesn’t prevent this from happening, and certain bacteria and mold is actually more common in water. If you don’t take the proper steps to prevent this from happening, you could be introducing harmful bacteria, fungi, and pests into your garden. Boiling the water to sterilize it and keeping your banana water in a sealed container can help prevent this, but that means you’ll be putting in a lot more effort for no reward.

Banana water alternatives

So, if banana water for plants isn’t effective, what are some better alternatives? Perhaps the most obvious one is to purchase fertilizer to feed your plants. Store-bought fertilizer undergoes tests to ensure it has the proper amount and ratio of nutrients, so you can be sure your plants are getting everything they need. There are even organic options available, so you can keep your garden organic if you prefer.

If you aren’t interested in store-bought fertilizer and are determined to use your banana peels, then a better alternative is starting a simple home compost bin. Compost does take longer to make than banana water, but it preserves a lot more of the nutrients, and you can use more than just banana peels! You don’t need a massive container or tons of space, either. A simple empty garbage can with a lid is all you need, plus a bit of soil, food scraps, and some paper or cardboard to get started.

Not every gardening trend is a winner, but it’s important to keep experimenting and trying new things. While banana water for plants isn’t the best idea, the next gardening trend just might revolutionize the way we grow plants. Stay curious about the world and test things out for yourself if you aren’t sure about them. Who knows, maybe you’ll be the one to come up with the next hot gardening trend that way.

Here are the best flowers to plant this coming fall season
End the growing season right with these flowers

What do you do when the summer flowers in your yard get tired and begin to die back? Hit the landscape refresh button with festive autumn color. Depending on your growing zone, late summer or early fall is the time to switch out summer annuals for fall flowers. There are many autumn flowers to choose from, and even some foliage plants that can serve as excellent accents. Whether you're looking for a few small plants to hold your garden over until spring or want to dedicate your entire garden to the season, these fall flowers are a great place to start.
Annual fall flowers

These cool-season annuals will add brilliant color to any garden. Whether you're looking for a few flowers to grow in pots on your front porch or a wide variety to fill your garden with fall beauty, we've got you covered.
Chrysanthemums
Mums display mounds of color in autumn shades of white, peach, yellow, orange, bronze, and red. Even the flower types offer variety, such as button, daisy, spider, quill, pompon, reflex, and incurved flower styles, just to name a few. Around this time of year, you’ll find them everywhere, from the garden center to the grocery store in pots ranging from 2 inches to 2 feet. Mums work virtually everywhere, from tabletop decor to instant container garden color to massed landscape plantings.
Pansies
Pansies deliver long-lasting, cool-season color in nearly every shade imaginable. Heavy, consistent flowering and outstanding versatility make pansies the most useful flower for fall. Use them for annual color beds, mixed container plantings, and even hanging baskets. Traditional varieties grow in mounded forms, while some newer types trail. In mild climates, pansies bloom straight through winter. In colder areas, they'll return to rebloom in spring.
Violas
These small-flowered relatives of pansies offer greater resilience to adverse growing conditions with perhaps even heavier flowers than their cousins. Violas come in seemingly endless color options, including many multicolor blooms. They offer outstanding cold tolerance and perform well in soggy, wet weather. The small flowers work best in locations where they'll be seen from a close distance, such as annual beds in high-traffic areas or in container gardens.
Dianthus
Dianthus offers masses of brilliant color and delightful aroma. This low-growing annual comes in a range of colors in white, pink, red, and purple tones to complement any garden. Use them in containers or mass plantings,; however, be sure to grow them where you can thoroughly take in the fragrance.
Snapdragons
Snapdragons are perfect for the shoulder seasons, preferring the cool days of fall and spring to the sweltering summers. With both dwarf and standard varieties to choose from, snaps are useful for borders, adding height to mixed garden and container plantings, and they hold up quite well as fresh-cut flowers. In mild regions, snapdragons return to flower again in spring.
Ornamental peppers
These veggies are meant to be seen, not eaten, and they're just right for autumn. The small, colorful peppers ripen to shades of yellow, orange, red, and purple. With several varieties available, the fruits come in different shapes and sizes, from the globe-shaped "Black Pearl" to the "Chilly Chili," which looks like tongues of fire.

Did you know snake plants weren’t always considered a member of the Dracaena species? They were actually classified as Sansevieria plants until 2017.
