If you’re lucky enough to live in a climatic zone that can support growing plantain trees, you definitely need to try your hand at it!
Plantains are much like bananas except the fruit is more firm and starchier, lending itself better to cooking.
Plantain trees need care similar to banana trees – keep the soil moist, protect it during cold snaps, and feed it a slow-release fertilizer about once a month during the active growing season.
A well-fertilized plantain tree will yield up to ten times more than an unfertilized tree.
With that being said, what is the best fertilizer for plantains? In this post, we are going to look at 4 of our favorite options on the market.
So, let’s get started…
What is the best fertilizer for plantains?
The quick answer is that plantain trees are heavy feeders. For that reason, look for a fertilizer that has a nice blend of the top nutrients, nitrogen, phosphorus, and potassium.
In addition, granular forumlas work better than water soluble for trees because they are classified as slow release. This means rather than getting all the nutrients at once, they are slowly release into the soil over a period of time.
Here is a quick preview of our top 4 options when it comes to feeding your plantains.

What to look for in a good fertilizer for plantains?
Before we take a closer look at some great options on the market today, let’s talk about what to look for in a good fertilizer.
Plantain trees are heavy feeders that prefer a balanced fertilizer that contains nitrogen, phosphorus, and potassium in a similar ratio.
To see optimum results in your fruit trees look for a fertilizer with a nutrient ratio of approximately 8-10-8.
These numbers found on the label are the N-P-K ratio (nitrogen-phosphorus-potassium); the consumer can look at this ratio and determine the percentage, by weight, of nutrients in the bag.
For example, a 10-pound bag of plant food with an 8-10-8 fertilizer formula would contain 0.8 pounds of nitrogen, 1.0 pounds of phosphorus, and 0.8 pounds of potassium.
Why are these nutrients important?
To put it simply, nitrogen is going to keep the plant looking green. Phosphorus is needed for flowering and strong roots.
Lastly, potassium helps the overall health of the plant.
So, as you can see each of these nutrients is essential in keeping your plant healthy.
Once you have selected the plant food with the right combination of nitrogen, phosphorus, and potassium it is important to apply it properly.
Applying fertilizer to plantain trees is fairly straightforward. There are many fruit tree specific fertilizers that provide the essential nutrients banana trees need.
Start by looking for a product with balanced nutrients or one slightly higher in phosphorus to promote flower and fruit development. Then you can then choose whether you want to feed organically or not and if you prefer a granular or liquid concentrate formulation.
At this point we have talked about what to look for in the right fertilizer and how to talk about it, let’s take a look at some of the best options on the market.
