When looking for the best fertilizer for palm trees, there are a few things to keep in mind.
Not only do you need to find one that provides the right balance of nutrients, but you also have to be sure that it delivers them in the right way.
Because of the environment where palms primarily grow, the type of soil, and how it interacts with the fertilizer are important factors to consider. Whether your palm is growing outdoors or growing in a pot indoors matters, too.
Here are some things to think about before choosing the right fertilizer for your palm tree.

Palm Tree Fertilizer Requirements
Palm trees usually grow in tropical or subtropical climates where the soil is sandy and rain is plentiful. Nutrients are quickly leached from this type of soil, particularly during heavy rains, which is why fertilizer is so important.
Palm tree fertilizer needs to replace the lost nutrients and maintain them. That’s why it’s really important to use a long-lasting fertilizer for palm trees. It fixes the immediate problem and helps prevent more in the future.
All plants, including palm trees, require a combination of nitrogen, potassium, phosphorus, and other micronutrients. In palm trees, deficiencies of different nutrients present in various ways:
- Magnesium (Mg). Not enough magnesium presents as yellow or orange leaves on mature trees or deep green leaves in younger trees of new foliage.
- Potassium (K). A deficiency in potassium can cause leaves to develop yellow or orange spots.
- Manganese (Mn). Low manganese causes new growth to turn yellow or wither.
- Iron (Fe). A palm without enough iron will also have yellow leaves, particularly on new growth, though the veins will remain green initially.
- Nitrogen (N). Nitrogen deficiency presents as a uniform yellowing of the palm leaves.
These deficiencies not only affect the way the plant looks, but they will also eventually kill the palm if not corrected. Using the right type of fertilizer with the right application is really important.
When choosing your fertilizer, the longer-lasting is it, the better. There are some slow-release formulas that are really effective at maintaining the right level of nutrients over time, even if they’re leached away.
These products are available in several forms including granules, liquids, pellets, and spikes. Although they’re applied differently, most are formulated to work over long periods of time. In fact, some only need to be applied twice a year.

Wet the ground slightly before driving the spikes into the ground at least three feet apart from one another.

When Should You Fertilize a Palm Tree?
As we mentioned, most palm tree fertilizers are long-acting and only need to be applied a few times a year. Each product has its own schedule but here are some general guidelines as to when you should apply fertilizer.
If you’re planting a new palm, it’s usually best to wait until the plant puts out a new spear to add fertilizer unless the label specifically states it’s for new plants. A new spear that comes right from the heart of the bud is an essential growth point for a new plant and signals a healthy plant.
Established plants are a little different. Their nutritional needs can be met by following a yearly schedule but that varies from one product to another. It’s really important to use a fertilizer that’s made especially for palm trees and follow the directions on the package.
Some products only require application twice a year, once in the spring and again in the fall. Others should be applied every two to three months. Generally, how often fertilizer needs to be applied depends on the soil and climate.
In warm climates where the temperature doesn’t go below freezing, palms may need fertilizer up to four times a year. Although they go dormant when the temperature drops, in warm climates, they grow continuously throughout the year and require more nutrients.
Although they’re primarily known for growing in warm or tropical climates, palm trees can grow just about anywhere. If you live in a climate where the temperature regularly goes below freezing, some recommend that you stop fertilizing the plant two months before the first frost.
Continuing to fertilize a palm tree in the winter can encourage the plant to continue growing even though conditions aren’t ideal. This may result in weaker growth and vulnerable leaves.
Another school of thought is that you should fertilize your palm before the cold weather hits. The thinking is that the availability of nutrients can help the plant stay strong over the winter and be ready for growth when the weather warms.
So, should you fertilize in the winter or not? There’s no clear answer either way. Ask people in your area who also have palms if they’ve had success either way before trying it for yourself.
Again, it’s important to read the package and follow the directions for the fertilizer you choose. Each is formulated differently and should be applied according to the manufacturer’s recommendations.
How Much Fertilizer Does a Palm Tree Need?
It’s hard to give the exact amount of fertilizer that a palm tree needs because there are so many variables. It depends on the climate, where the palms are planted, the type of soil, and what fertilizer you choose. Your best bet is to follow the directions on the package.
Remember, in sandy soil, palm trees rely on the nutrients that fertilizer provides. It’s important to follow the directions carefully to make sure your palm gets what it needs to thrive.
It’s always better to under fertilize than over-fertilize so if you’re unsure, start with a low amount and add a little more as needed. There’s no way to correct over-fertilization and it could cause problems long into the future.
How to Fertilize a Palm Tree?
In addition to using the right type and amount of fertilizer, applying it correctly is also really important. Follow the directions on the package carefully because too much fertilizer placed too close to the tree can have disastrous effects.
Most of the time, fertilizer is placed at the drip line – the outer circumference of the branches where water drips to the ground. Spikes are usually driven into the ground at this point and granules are distributed along the drip line as well.
Potted palms are an exception to this rule. They’re a completely different scenario because the soil, roots, and nutrients are contained and leaching isn’t a problem. Salt can accumulate quickly, though, so monitor it closely.
In addition, there are some other important things to keep in mind when fertilizing palm trees. Here are some helpful tips to set you up for success.
1. Only apply fertilizer when the soil is moist and water thoroughly after fertilizing. This helps the nutrients get down to the roots.
2. Don’t fertilize dry soil because the roots can burn easily which can damage or kill the plant.
3. It’s always better to use too little fertilizer than too much. Under-fertilizing can easily be corrected but over-fertilizing could kill the plant.
4. A 3:1:3 NPK ratio with added magnesium and calcium is ideal.
5. Slow-release is better than quick-release for outside palms. It provides long-term coverage and doesn’t need to be reapplied too often.
6. Don’t shy away from different combinations of fertilizer. A slow-release spike fertilizer used with organic granules or a quick-release liquid might do the trick. Just don’t overdo it!
7. Apply mulch over the soil if possible. It helps improve the overall quality of the soil and prevents it from drying out too quickly. Some people even add organic granules over the mulch for added benefits.
8. Granular fertilizer should always be placed at the drip line. Avoid getting too close to the trunk of the tree unless the manufacturer’s instructions indicate otherwise.
9. Don’t fertilize new palms right away. Remember, it’s best to wait for a new spear to develop so you know that the water content is good and there’s less chance of shocking the plant. It can take as long as four to six weeks.
10. If you’re growing your palm in a pot, keep in mind that potted plants have a tendency to collect salt buildup. Check regularly and leach the plant outside if necessary.
11. Store unused fertilizer in a water-tight container. If it gets wet, the nutrients will be leached out and it won’t be as effective.
Conclusion
Remember, there’s more than one way to successfully fertilize a palm tree. There are so many factors that affect how a plant grows which is why it’s so important to choose the best palm tree fertilizer for your unique situation.
A palm tree planted in sandy soil in a tropical climate has different needs than one planted in dense soil in a cool place that goes dormant in the winter. And both of these plants are different than an indoor potted palm.
It’s very important to follow the instructions for the product that you choose. While there are a lot of things that all fertilizers have in common, each is formulated differently. Some are great for potted plants while others can help maintain a healthy palm outside for multiple seasons.
It’s great to know that you should only apply fertilizer when the soil is moist. My wife and I are wanting to improve the look of our garden and we were wondering when is the best time to fertilize the soil in the yard. I’ll be sure to tell her that we should only have fertilizer applied to the yard when the soil is moist.
