Nutritive Requirements of a Palm Tree

As we think of palm trees there is a universal thought that comes to most minds. Gorgeous tropical beaches with turquoise water, white sand, sunny days and long shores, where we spend days relaxing and sipping on cocktails.

However, surprisingly, you can grow palm trees in so many more places than in tropical islands and countries.

They can grow in temperate climates as well and you can even find them in southern parts of Canada. (I couldn’t believe it either)

This is great news for every person who lives in places far away from the tropical parts of the world, but also not so great news since your palm tree needs a lot of care and nutrients for steady and high-quality growth.

The most important factor is its soil, as it is the sole provider of the necessary food for this gorgeous tree.

The soil can ‘make-it-or-break-it’ in the process of caring for palm trees indoors, so please be careful when choosing it, or keep reading on to see what the best kinds are 🙂


The most important elements for all the plants, and thus all palm trees and their steady growth, healthy green leaves, elongated root cells, and strong roots are:

Nitrogen (N)

This is thought to be the most important element for a plant’s growth. It comes from a chlorophyll molecule, which is the molecule that gives every plant a green color and takes part in the process of photosynthesis through which plants generate their food.

Nitrogen is also the most important ingredient of a substance called protoplasm.

This substance is transparent and presents the living matter in all cells and is extremely important.

The lack of nitrogen will primarily show in leaves turning pale green or yellow, especially older ones.

Magnesium (Mg)

There are thirteen mineral nutrients that you can find in soil and this element is one of them.

As it dissolves via water presence it gets absorbed by plants’ roots.

This element is a “powerhouse” for the process of photosynthesis.

Chlorophyll is the crucial molecule for this process, but without magnesium, it can’t capture solar energy that is required for the food generation.

It is also crucial for plants’ growth and other functions.

Magnesium deficiency is often obvious as it shows via red, brown and purple stains on leaves and it also turns them yellow.

Potassium (K)

Potassium is the second most important “ingredient” for your palm tree as it affects it in every way: its shape, size, color, reproduction, and overall growth.

This element is crucial in the process of ATP production (adenosine triphosphate) – a molecule that is the main source of energy for various processes in a plant.

This molecule is crucial for regulating water uptake and loss in plants and is needed for protein creation.

Lack of this element will affect the growth of your palm tree and root development, and it will be obvious because leaves will look scorched with brown and yellow spots and have purple stains on their undersides.

Iron (Fe)

Iron is a crucial element for all the plants, thus palm trees as well, because it takes part in many plant functions, such as creating chlorophyll, transferring energy, fixating nitrogen and other functions in a plant’s metabolism.

The lack thereof causes a disorder called “lime-induced chlorosis” and can be caused in many ways: by the lack of manganese, high levels of nitrogen and zinc, too much water in the soil, too much fertilization, or high soil pH (higher than 6.5).

A sure sign of iron deficiency is chlorosis or plainly said yellowing around the veins of the baby leaves.

Manganese (Mn)

Plants require manganese in large quantities, just like they do iron.

It is used in major processes, like photosynthesis, respiration, and assimilation of nitrogen. It is crucial for growth, especially root growth.

Manganese deficiency is often mistaken for iron deficiency, as it shows in a very similar way – interveinal chlorosis, and young leaves turning yellow rapidly for no obvious reason.

The pH value of soil affects the uptake of manganese and can stop it if it goes above 6.5.

As you can see, improper usage of these elements or soil mix that is unfit for the palm trees can be fatal for your plant and its health.

The Best Fertilizer For Palm Trees you can find Online

I have covered 8 absolutely amazing palm tree fertilizers and it hasn’t been easy to pick these eight out of all the choices, let alone pick only one.

However, because I know how hard it can be to make a decision, especially at the beginning of the palm tree growing process, I will do it for you.

I would always first choose Jobe’s Organic Palm Tree Granular Plant Food because of its amazing traits. This food is organic, renewable, biodegradable, and overall eco-friendly. This product will keep your plant safe from diseases. It will help it grow thanks to many different nutrients and their good balance. Most importantly it will help increase the absorbing surface of the roots many times, so they will absorb those elements and water even better.

The Best time to Fertilize your Palm Tree?

This isn’t an easy question since it depends on how old your tree is, what type of soil it is surrounded with, what the climate is like, what type of fertilizer you use, etc.

In case I just planted it, I would wait for it to start showing first signs of growth, such as a new spear, and then fertilize it. Unless the fertilizer you are about to use is made specifically for brand new plants.

Most of the times, fertilizer is supposed to be used from two to several times a year. I fertilize my palm trees first in March when they “wake up” from the dormant state in winter and need many nutrients to support their active growth.

The second time is in October before their dormant phase, which is winter, so they have enough nutrients for winter, especially since my fertilizer is slow releasing.

Some people say you shouldn’t feed your plants before the winter, as they will continue to grow fast, but not as strong, as they are in a dormant phase, however, I don’t agree with this and believe they still need their nutrients.

Your climate also dictates the number of fertilizations – warm climate causes your plant to almost skip the dormant phase and it grows more-or-less constantly during the year, so you should fertilize it several times a year.

If you aren’t sure what action to take, please advise yourself with your neighbors or other palm tree growers from your area. They will give the best advice possible.

How much to Fertilize your Palm Tree?

Please, please, please read the direction on the fertilizer you are about to apply. I cannot stress enough how important this is. It doesn’t take more than a minute and can make a life-changing difference for your palm tree.

The soil around your plant is the sole provider of its nutrients, thus its “wellbeing” depends on it. The last thing you wish to do is to poison the soil with too much fertilizer and burn (kill) your plant.

Every package will tell you how much apply to the soil depending on the size of your plant.

If you don’t have access to instruction for any reason, please apply small dosages and then observe the results.

How to Fertilize a Palm Tree?

The process of palm tree fertilization is pretty simple-however, there is some information you should have in mind before you begin with it.

  1. If you are using spikes or granules you should know they are driven into or applied onto the ground so they follow the widest circumference of the tree’s branches, so that water drips on them.
  2. You must wet the soil before the feeding process because the dry one will burn the plants. Exposure to much nitrogen without any moisture can be overwhelming for a plant and damage it severely.

If you overfertilize your plant, please remove any leftover fertilizer if you can, or rinse it thoroughly, especially if it’s in a pot. Also, move it to a shady area, since sun exposure causes plants to absorb more.

  1. If your palm tree is located outside it is better to use slow-releasing fertilizers, as they will feed the plant longer and more consistently.
  2. In case you’ve had experience with different fertilizers don’t be afraid to combine them. For example, you can drive spikes around the drip line and then add organic granules or quick-releasing fertilizer. However, please be careful so you don’t exaggerate.
  3. It is better to wait for a baby plant to grow and show how healthy and stable it is, then adding fertilizers immediately. This is because several things could go wrong and you will hardly know what the reason is – is it the fertilizer or something unrelated. By waiting you will at least cross off some reasons.
  4. If your palm tree is located in a pot is wise to report it once in around 2 years, as much more salt and mineral can buildup and affect the plant and its roots. By repotting it, your plant will get a fresh start and new soil, so it will grow faster and stronger.
  5. Mulch application is always a good idea when fertilizing palm trees. You should apply it around the trunk, around 5 inches away from it in a layer 3-7 inches thick and around 2-3 feet long. The best one to use is the sterilized commercial one, since creating your own can cause plant diseases much more likely.

Fertilizers You Should Avoid

All of us plant growers wish to provide our plats with the best nutrients and provide their abundance. However, the balance between their amounts is also crucial and affects the lives of all plants, especially if it’s improper.

For example, if you use a fertilizer that is very high in nitrogen, but low on potassium, you will create chaos. Nitrogen will cause your palm tree to grow (that is amazing), but lack of potassium will affect the strength of the plant and it won’t be stable and healthy.

This way you will cause much worse effect than if you stopped fertilizing your palm tree altogether.

Frequently Asked Questions

Will vinegar kill palm trees?

If you apply it rarely and wisely, it won’t damage your palms, but you have to be extra careful. However, if you notice that leaves get damaged due to excessive use of vinegar, it might lead to the death of the plant eventually. That’s because your palm won’t be able to photosynthesize properly.

Is Epsom salt good for palm trees?

When used reasonably, it is very beneficial to your plants. One of its greatest advantages is that it can make up for the lack of magnesium deficiency. When palms receive enough of this valuable ingredient, their leaves will look healthier and more attractive.

Is Miracle-Gro good for palm trees?

Yes, this mega-popular fertilizer is good for palms as well. It works fine for other tropical plants as well. As for the frequency of application, once per three months is fine.

What is the best natural fertilizer?

Options are numerous. For example, grass clippings and weeds work great, provided that you didn’t treat them with some herbicide. Cow, chicken, or horse manure is excellent as well, but never use it in raw form, as it is too acidic. Eggshells, banana peels, and various kitchen scraps are also great natural fertilizers.


I hope that this guide and advice on palm tree care and fertilization will be helpful with your endeavors and will stick in your mind, so you don’t make common mistakes and cause fatal scenarios for your plant.

I hope you found new and interesting information that will motivate you to care even more for your plants, or start doing so if you haven’t been a grower so far.
