Put dehydrated, dried peels into a blender or a food processor and grind until they become a powdered consistency. Water one plant with 2 cups of water mixed with 2 tablespoons of the powder. Store the dry banana peel powder in an airtight jar and place it in the freezer.
You can water your plants with banana peel water fertilizer once a week. Many plants require watering once a week, so you can use compost tea during each hydration session. However, if your plants need a drink more often in the summer, stick to only using banana water once a week.
Homemade liquid fertiliser and non-toxic pest repellent
Start by cutting your banana peels into small pieces and putting them in a bucket or container and covering them with water. Leave them for two to three days. Stir occasionally. Strain and use the liquid to water your plants.
Is banana water safe for all plants? Mostly, yes. Banana water for plants is safe to use, and it won't inhibit your plant's growth one bit. However, conventionally grown bananas are often sprayed with synthetic pesticides, so you might not want to use banana water on food crops if you keep an organic garden.
This means potassium-rich banana peels are excellent for plants like tomatoes, peppers or flowers. Banana peels also contain calcium, which prevents blossom end rot in tomatoes. The manganese in banana peels aids photosynthesis, while the sodium in banana peels helps water flow between cells.
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 even cockroaches.
Is banana peel fertilizer good for all plants? Using banana peel as fertilizer will boost some plants more than it does others, particularly those that blossom and fruit. However, since it isn't high in nitrogen, it's not going to be enough to help all plants grow to their best potential.
You can run your banana peels under running water or soak them and then blend them in a food processor to make a slurry of nutrients for your plants. Side dress this slurry by burying it in a shallow slot in the soil near the plant.
How Does This Work? Banana peels contain lots of nutrients, including potassium, phosphorus, magnesium and calcium—all of which are needed for good plant growth. Soaking the banana peels allows the nutrients to leech into the water, and once it hits the soil, the roots grab all those sweet, sweet minerals.
Cut up the bananas, add some brown sugar, and then store in an airtight container at room temperature for two weeks. Use regular water to dilute the fermented banana water before applying it in your garden.
Banana peel fertilizer is perfect for plants with low-nitrogen requirements such as tomatoes, peppers, cucumbers, and even radishes. But don't worry, even nitrogen-loving plants will benefit from the use of banana peel fertilizer.
Dilute your fermented banana water with a 50/50 ratio of regular water and then put it to use. Water the soil with it once a week. Put the water in a spray bottle to use as a foliar spray, which will be absorbed through the leaves, which is faster and gives an immediate boost to your plants.
Drainage is the natural or assisted elimination of excess water that could reduce the development of banana plants. Indeed, since too much water deprives roots of oxygen, even temporary asphyxiation can cause irreversible damage.
Potassium power! Optional: Grind three eggshells into powder. Combine with four tablespoons of banana peel powder and one tablespoon Epsom salt. Put the mixture into a spray bottle, and fill to the top with water.
Probably not. Bananas and banana peels are high in potassium, but they aren't particularly loaded in nitrogen and all the other nutrients that plants need to grow. If the peels aren't high in a variety of nutrients, they won't provide those nutrients to plants.
Eggshell Benefits
As it happens, eggshells can provide all the calcium carbonate the soil needs, which helps to lower the soil's pH level and make it more alkaline as opposed to acidic. This is incredibly beneficial for plant growth because many plants prefer to grow in soil that has low acidity.
Banana peels: The peels of bananas take up to 2 years to biodegrade.
The NPK value for banana skins is 0.6-0.4-11.5. But this is the value for dried banana skins since all of the above values are calculated on a dry weight basis. The NPK of fresh banana peels is 1/5 of that, making an NPK of 0.1-0.1-2.3.
“Did you know that bananas are filled with calcium, phosphorus and potassium? They're great for your indoor plants all you need to do is pop a banana peel in a glass of water let it sit for 24 hours and then pour on your plant,” she says.
Fiber-rich banana peels can help regulate the digestive system, easing both constipation and diarrhea. This can be a particularly important benefit of banana peels for people with Crohn's disease or irritable bowel syndrome. Vitamin A can help keep your eyes strong and healthy.
