How to Make Banana Peel Water for Your Tomato Plants?

The shared secret to big, red, and juicy Tomatoes is using the best organic fertilizer. And, interestingly the Banana peels that go straight into your garbage bin can do wonders for your Tomato plants. 

You can make Banana peel water for Tomato plants either through dehydrated Banana peel powder or fresh peel. Cut a Banana peel into 1-2 inches pieces, dry it, grind it into a fine powder, and mix it with water before applying. 

Soaking Banana peels allows water to marinate nutrients, and when applied to soil, the plants receive all sweet minerals for healthy growth. 

So, let’s learn how to make DIY Banana peel water for your Tomato plants effortlessly. 

Is Banana Peel Water Good for Tomato Plants?

Banana peels boast 40% of rich potassium to offer the essential macronutrients for Tomato plants.

Potassium regulates and improves water uptake, which helps boost plants’ immunity against environmental stress, diseases, and pests and promotes root development.

As Banana peel water adds potassium to your Tomato plant, adding it weekly to the Tomato plants can solve problems like brown scorching, leaf tip curling, and yellowing leaves.

Banana peel water is excellent for plants that require low nitrogen, such as Tomatoes, peppers, cucumbers, and radishes.

Note: Banana peel water is not a complete fertilizer for Tomato plants as it supplies plants with only potassium and a scanty amount of magnesium, calcium, and phosphorous. 

Also, many plant parents have complained about its foul odor, ants, fungus gnats, and pests problems after using it.

When breaking down peels, fungi and bacteria leave a stink, so leftover peels on decomposition permeate bad odor, which attracts pests. 

But if you keep or apply Banana peel water on Tomatoes grown outdoors, you will not have to bother about such issues. 

If you have spare or spent coffee grounds, use them for roses!
