Bananas used to be the sole province of commercial growers, but today’s different varieties allow the home gardener to grow them as well. Bananas are heavy feeders in order to produce sweet fruit, so feeding banana plants is of primary importance, but the question is what to feed banana plants? What are banana fertilizer requirements and how do you fertilize a banana tree plant? Let’s learn more.
Like many other plants, banana fertilizer requirements include nitrogen, phosphorus, and potassium. You may choose to use a balanced fertilizer on a regular basis that contains all of the micro and secondary nutrients the plant needs or divide feedings according to the plant’s growing needs. For example, apply high-nitrogen rich fertilizer once a month during the growing season and then cut back when the plant flowers. At this point, switch to a high phosphorus or high potassium food.
Fertilizing a banana plant with additional nutrients is fairly rare. If you suspect any type of deficiency, take a soil sample and get it analyzed, then feed as necessary per results.
As mentioned, banana trees are heavy feeders so they need to be regularly fertilized to be productive. There are a couple of ways to feed the plant. When fertilizing a mature banana plant, use 1 ½ pounds (680 gr.) of 8-10-10 per month; for dwarf indoor plants, use half that amount. Dig this amount in around the plant and allow it to dissolve each time the plant is watered.
Or you can give the banana a lighter application of fertilizer each time it is watered. Mix the fertilizer with the water and apply as you irrigate. How often should you water/fertilize? When the soil dries out to about ½ inch (1 cm.), water and fertilize again.
If you are choosing to use high nitrogen and high potassium fertilizers, the method is a bit different. Add the high nitrogen food to the soil once a month during the growing season at full dose according to the manufacturer’s directions. When the plant begins to flower, cut back on the high-nitrogen fertilizer and switch to one that is high in potassium. Stop fertilizing if the soil has a pH of 6.0 or under or when the plant begins to fruit.

Using coffee grounds in your soil isn’t as simple as some green and eco tips you might learn about online would have you believe. You see, used coffee grounds have had some of their acidity reduced to nearly neutral, sometimes lower, other times higher. It depends on the brand.
In most cases, after the coffee has been brewed, the used coffee grounds are pH neutral. However, when you put the grounds into the soil or compost, there’s a different reaction than just fertilizing your plants. That’s because the caffeine left in the coffee grounds can compete for other nutrients when they’re just blanketed on top of soil.
You only need a thin layer and spread sparingly so the grounds don’t compact together.
One of the safest ways to use coffee grounds is to add it to your compost bin with other brown organic matter or to leafmould. This way, it’s not only the coffee grounds, but it’s adding more nitrogen, phosphorous, potassium, and magnesium to the compost you’ll eventually be using in your garden.
Coffee grounds are also good for repelling pests (see other methods in my post about getting rid of bugs on your plants) and encouraging earthworms into your garden soil. Good times.
If you don’t brew your own coffee, opting to buy from your local coffee store, then that’s where to get used coffee grounds – for free! That’s because, it costs coffee houses more to get rid of used coffee grounds because if it’s not getting used, it goes to landfill.
From there, it emits methane – “a greenhouse gas more harmful than carbon dioxide.” Source: (and further reading: https://blog.epa.gov/2009/02/24/climate-for-action).
So, by using coffee grounds in your compost or adding to your leafmould, you’re playing a part in reducing landfill waste too. That’s a win all-round. Take it!
As mentioned though, be careful with quantities because you don’t want highly acidic coffee grounds to be competing for soil nutrients. That’s why it’s not advised to add it directly to your soil, but rather introduce it to your homemade compost or leafmould.
If you have a lawn, the worst thing to do is throw away your grass clippings. They’re a superb source of nitrogen. Additionally, your soil will also benefit from added potassium, phosphorous, chlorophyll, and amino acids.
To make your compost effective, you need to mix green material with brown. Obviously, your grass clippings are the green. It’s nitrogen rich. You then need to balance that with carbon rich material for a good quality DIY compost.
For that, Cornell University has a good table of rich sources for both and guidance notes for using carbon and nitrogen ratios to make quality compost.
The nuts and bolts are – for nitrogen rich sources, there’s grass clippings, the coffee grounds (mentioned above), and vegetable scraps. Manure’s listed too, but chances are, you don’t have that laying around your house. This is about household items you can use as a fertilizer, so…
Getting back to the fertilizer, the way to make this with grass clippings is to make a green tea. Fill a net bag with your grass clippings and place that in a large bucket. Fill with water and leave the clippings to steep. A five-gallon bucket or larger will do the job.
Let the grass clippings soak for a few days. What will happen is the chemicals from the grass clippings will release into the water. You can then use that water to feed your plants, then add the grass clippings to your compost pile. A 2-for-1 on what would otherwise be wasted.
Gelatin will only be effective if it’s unflavored. Flavored gelatin has added sugars, which can be damaging to plants.
Unflavored gelatin is used to make low-calorie recipes, and if you have this in your kitchen cupboard, you have packets of nitrogen rich fertilizer ready to go.
Years ago, the Brand ‘Knox’ – a manufacturer of gelatin had a theory that the gelatin could be a rich source of nitrogen for plants. To test their theory, they had the University of Houston test it.
Two years were spent testing 49 species of plants and the study conclusively found that the gelatin does indeed provide a rich source of nitrogen to plants.
Asides from low-calorie recipes, Knox has a web page detailing different uses for gelatin, ranging from plant food to skin care.
The original Knox Gelatine is sold on Amazon.com. There are other manufacturers of unflavored gelatin, however, Knox is the product that’s been tested and proven to be beneficial when used as a fertilizer.
To make a batch of fertilizer, the Knox instructions are:
Plants will only need this once per month and it can be used on both indoor and outdoor plants.
Banana peels can be a source of up to 42% potassium and up to 25% phosphorous. There’s also the additional calcium, magnesium and sulfur in banana peels, which is why it’s among the best organic material to use to make a homemade fertilizer.
That said, there’s a huge downside and that’s insects. If you just plant banana peels in your soil so it decomposes to release the nutrients, chances are, you’ll attract a bunch of insects.
A more worrying problem is that bees can mistake the scent released as a defense hormone. It’s not a good idea to put banana peels in the soil of household plants.
What is a good idea is to puree the banana peels, or soak the peel in water inside a sealed mason jar for a week, then drain it with a sieve and use that water as fertilizer.
Alternatively, you can bake the peel and then grind it down to mix into your soil. The video below shows you how…
Now, the one thing that banana peels don’t have is nitrogen. To add that into the mix, you can add in…
Eggshells have a few essential nutrients for plants. Mostly calcium, but they’re also sources of selenium and nitrogen.
You can add eggshells into your mulch, but a faster way to get the same benefits is to crush the eggshells up and boil them.
To make an eggshell brew, you only need a pot large enough to boil a gallon of water and just 30 grams of crushed eggshells.
Boil the crushed eggshells for a few minutes, then leave them in the standing water with the lid on for a few days, then strain.
If you’re using this on outdoor plants, it’d be a good idea to leave the water in a sealed container outdoors to avoid adding too hot of a water temperature to your plants, which could shock them.
For those with a wood burning stove, there’s a lot of nutrients in the ash. More so if you’re burning hardwood.
Nitrogen and sulfur are lost during the burning process as they’re released as gas. But what’s left in the ash is decent trace amounts of potassium, magnesium and get this… up to 25% calcium carbonate. That’s a good pH balancer there for acidic soil.
Wood ash is only good for your garden when used in moderation. You don’t want a thick layer of this. Just a light sprinkle over the top of the soil and it’ll eventually work its way down, adding the nutrients to your soil.
Point of note: Any soil you plan to grow potatoes with, do not use wood ash. It can cause potato scab.
Any food you boil, there’s nutrients in the water. Don’t toss it.
Just as you’d use the water from a netted bag of grass clippings as a fertilizer, and eggshell tea for the same, you can do the same with boiled foods. Recycle the water. Drain it into a separate container, let it cool and then water your plants with that.
The nutrients will differ depending on what you’ve boiled. Veggies, rice, eggs, pasta, potatoes and spinach are all examples of foods you can boil and use the water from cooking as fertilizer for your plants, provided you don’t add salt to the water.
The most organic fertilizer you can make is compost made from any product that started out from the ground with the help of a red wiggler worm.
These will eat all your vegetable scraps, fruits, paper, cardboard, potatoes (and the potato peelings), rice and coffee grounds. Cotton too.
To get started with vermicomposting, you need a worm bin. You can buy these online, or you can make your own.
You’ll also need the right type of worms. Those are Red Wigglers…
Red wiggler worms will eat half their body weight every day. To know how many red wiggler worms you need, weigh the garbage you throw out that could be used for composting. That will give you an indication of how many red wigglers you’ll need to start.
An interesting thing about this type of worm is they have both male and female organs, so the gender doesn’t matter, they will reproduce. When they do, they’ll eat through more waste, creating your compost faster.
The real gem though is in their poo. Worm excrement is the richest fertilizer you can use on your crops. In agriculture, it’s known as black gold because it can fetch a good price from farmers in need of high-quality fertilizers and this is the most top grade you can get.
To learn more about vermicomposting, some resources include:
String of bananas is a low-maintenance hanging succulent that doesn’t require much care.

Let’s look in more detail at how to grow a string of bananas indoors.
Deciding when to apply fertilizers to vegetable plants are sometimes more critical than the fertilizer choice itself. In general, most of the vegetable plants benefit from a fertilizer application at the time of the transplanting or soon after when the plant is few inches tall. Depending upon the vegetable type, it may need upfront soil amendments or supplemental fertilizer applications later in the season to perform optimally.
Before deciding when and how to fertilize the vegetable plants, general familiarity with the types of vegetables and how they grow is highly recommended.
Banana plants lacking in potassium and nitrogen often have light-colored leaves. While the pale leaf color is more closely related to a lack of nitrogen, lower yields of fruit are directly attributable to a lack of potassium in the soil. This is easily remedied by applying potassium nitrate to the soil and watering thoroughly. If your banana plants don't perk up, a soil or leaf analysis will tell you whether any additional micronutrients, such as iron, manganese or zinc, are needed to nourish the plants.
