Ingredients and Nutrients


Nitrogen is an excellent nutrient for a banana tree’s pseudostem and leaves. Nitrogen helps banana leaves maintain a healthy green glow and gives the banana plant sturdy stem support. As a result, banana plants will provide you with tremendous seasonal yields every year.


Phosphorus is necessary to give your banana tree a firm, healthy rhizome and excellent root strength. Use phosphorus during crop cycles three to nine months after planting.

When your plant is flowering and fruiting, adding phosphorus will fill the gaps lost within its suckers. Low doses of phosphorus cause stunted growth, leaf breakage, and unproperly formed roots.

Potassium causes conventional stimulation on young banana plant shoots. Additionally, it helps speed up the fruit’s ripening and maturity. Therefore, potassium is a great nutrient to help improve overall banana plant quality.

Natural Methods

Coffee Grounds

Did you know coffee grounds are a quality banana tree fertilizer? Coffee grounds happen to be a great source of nitrogen for banana trees.

To use this natural method, take used grounds and add them directly into the soil. Next, spread your coffee grounds evenly around the base of your plants, then water your banana tree regularly.

Additionally, leave coffee grounds to soak in water overnight, then try watering your banana tree with coffee-infused water.

Organic Composted Manure

Manure is another natural choice of banana tree fertilizer. Composted manure contains nitrogen, potassium, and phosphorus your banana trees crave.

Use composted manure at the base of your plant without allowing it to touch its stems. Remember, it’s impossible to overfertilize using natural solutions.

What Does Banana Tree Fertilizer Do?

If you are weighing the pros and cons of different banana tree fertilizers, here’s why they’re essential overall. Banana tree fertilizers will help improve the growth rates of your banana trees, leaf growth, and overall color.

Banana trees are heavy feeders and need these nutrient boosts to give you fruit. Non fertilized banana plants will grow, but they won’t provide you with fruit.

Pay Close Attention To Ingredients

Overfeeding your plants with commercial fertilizers could cause harmful effects. Adverse effects include smaller banana bunches, lower-quality fruits, and poor banana plant growth.

Remember to use only proper banana tree fertilizer amounts necessary; never more or less. Natural fertilizers are impossible to overuse, but with everything, use amounts that make sense for your plants!

Do Some Research!

I encourage you to dig into your own research and compare the results with this guide! In addition, the best way to research this topic more in-depth is to ask fellow gardeners for advice or talk to your local garden centers.

However, some of my best findings are from asking my friends, family members, farmers, landscapers, and gardeners. Ask them directly what methods they’ve found to be most successful.
