Things to Consider Before Buying

Liquid

Liquid fertilizers are simple and effective. They come in liquid form, so you don't need to mix or concoct (most of the time), and you can just apply the product directly to the plant. But do they have the specifications you need for your palm trees? Something to consider.

Water soluble

A close cousin to liquid fertilizers, water-soluble fertilizers easily dissolve into water and can be applied quickly to your palm trees. They can be used for most any palm trees but are ideal for those in landscaping. Frequent reapplications are typically needed.

Granular

Granular is what most normal people think of when they think of fertilizer, as they probably remember their dad spreading white pellets across the front yard in hope of a better yield (greener grass). The slower release of granular fertilizers also suits palm trees.

Spikes

Spikes dig around the spot you are trying to fertilize and slowly release nutrients over time. In this case, you would put them around your palm trees and hope for the best. They can have varied results so be sure to make your decision carefully.

How We Chose the Best Fertilizer for Palm Trees

There's no shortage of palm tree fertilizers. From spikes and liquid to solid fertilizers, you'll be overwhelmed by the number of fertilizers.


A palm fertilizer can be categorized based on its concentration, nutrient content, and texture. Here are the four types of palm tree fertilizers based on their texture and form.

  • Liquid
  • Water soluble
  • Granular
  • Spikes
  • NPK Ratio
  • Inorganic vs. Organic

Liquid

Liquid fertilizers come in liquid form. You can apply them directly to the palm tree or mix them with water. Most liquid fertilizers contain nitrogen, potassium, and phosphorus.


Some also contain micronutrients, such as sulfur, calcium, and magnesium. Plants can easily absorb liquid fertilizers, getting a quick nutrient boost. Although they are popular in commercial agriculture, you can also use liquid fertilizers for home gardening. 


Liquid fertilizers also allow precise applications. You can measure the amount in measuring cups to prevent over-fertilization. There are two main types of liquid palm fertilizers:

  • Organic: These fertilizers are made from natural sources. For example, they may contain animal manure or compost.
  • Synthetic: These are made of chemical compounds. Commonly used synthetic fertilizers include ammonium nitrate and urea.


When choosing between a liquid or granular fertilizer, you should consider the following:

  • Salt Content: Granular fertilizers, especially synthetic ones, contain a high salt content. Roots of palm trees may steer away from granular fertilizer bands. Thus, you should use liquid fertilizers as starters and then proceed to granular ones.
  • Spatial: Nutrients are more mobile in liquid fertilizers. So they can reach plant roots better than granular fertilizers.
  • Consistency: Each drop of a liquid fertilizer has the same nutrient content. But in a granular fertilizer, every granule has individual nutrients. The nutrients from granules away from roots may not be able to reach the roots.

Water Soluble

Water-soluble fertilizers dissolve completely in water. They are easy to uptake by plants and mainly contain mineral salts. Some water-soluble fertilizers also contain trace elements needed for palm development.


Most gardeners use water-soluble fertilizers in a hydroponic system. In this system, nutrient-rich water is circulated around the plant roots.


The main advantage of water-soluble fertilizers is quick availability. Since they dissolve quickly, the nutrients are readily available for the palm tree.


These fertilizers work well for any kind of palm tree. But they are the best for palms used in landscaping. Some examples include:

  • Areca Palm
  • Bismarck Palm
  • Coconut Palm
  • Pygmy Date Palm
  • Date Palm


If you plan to buy water-soluble fertilizers for your palm trees, note that they need frequent reapplications. You'll need to apply them every two weeks during the growing season.


Such fertilizers are most effective when you use them on moist soils. Dry soil lacks water and prevents nutrient absorption by plant roots.

Granular

Granular fertilizer is a palm tree food blend in the form of pellets. Most of these fertilizers are slow-release, which means they don't dissolve quickly.


Granular fertilizers are suitable for palm trees because they release nutrients slowly. As the pellets break down, the plants take up the nutrients.


Every granular fertilizer contains three essential nutrients; phosphorus, potassium, and nitrogen. Some varieties may also have additional micronutrients like iron and zinc.


Granular fertilizers are also available in several formulations for different palms. For example, some fertilizers are made for Areca palms, while others are meant for Coconut palms.


Granular fertilizers typically have the following:

  • A longer shelf life than other fertilizers
  • Slow-release capabilities, feeding the plant for a long time
  • Minimal salt content, reducing the risk of root burn


Before choosing a granular palm tree fertilizer, we recommend testing your soil. You can use a soil testing kit to check your soil's pH and nutrient content.


Some granular fertilizers are acidic and may not be suitable for alkaline soils. You should choose a fertilizer with the right nutrient ratios to match the requirements of your palms.


If possible, go for organic options. They are made of natural materials, like blood meal, fish emulsions, or bone meal. Do note that they may not be quick-release and take longer to release nutrients.

Spikes

Palm fertilizer spikes are long and narrow spikes made using compressed nutrients. Instead of measuring the fertilizer, you have to insert the spike containing the pre-measured fertilizer quantity into the soil around the palm tree roots.


Ideally, the spike should be 8 to 10 inches deep in the soil. But you should follow the manufacturer's instructions for precise insertion.


The spikes release nutrients slowly into the soil over weeks or months. It helps maintain a steady supply of nutrients for plants.


To get the best results with this palm plant food, it's best to dig small holes around the tree. Insert the spikes into the palm's dripline. The line is the area directly beneath and around the palm's canopy.

When rain, water, or condensation falls on the plant, it will fall on the spikes. The water carries the nutrients to the roots of the palm trees.


Besides, the bacteria and fungus in the soil also break down the nutrients in these fertilizers. Since these microorganisms work slowly, the spikes release nutrients over three or more months.


When buying palm fertilizer spikes, check the ingredients properly. Some fertilizers may contain formaldehyde. It can be harmful to plants, soil microorganisms, and the environment.

Although spike fertilizers are convenient to use, they have the following drawbacks.

  • Environmental Impact: If you do not insert the spikes properly, the nutrients may seep into the surface soil. These nutrients saturate the groundwater. They then run off into nearby water bodies, harming aquatic ecosystems.
  • Uneven Distribution: There's a higher concentration of nutrients around the spikes than in other areas. So, the area near the spike may be over-fertilized.
  • Limited Nutrient Variety: Most spike fertilizers only contain essential nutrients. They may lack trace or micronutrients that can help in palm tree growth and development.

NPK Ratio

NPK ratio in fertilizer is the ratio of nitrogen, phosphorus, and potassium in a fertilizer product.


There are many manufacturers making fertilizers. Similarly, there are many blends of nutrients, each made for different purposes.


But all fertilizers must have a uniform information system to help buyers compare products. NPK ratio is that information. It is short for:

  • N: Nitrogen
  • P: Phosphorus
  • K: Potassium


K is the element symbol for potassium. It is used instead of 'P' because the letter is already used for phosphorus. Here are the roles of these nutrients in palm tree growth.

  • Nitrogen: It is needed for leaf growth. Plants that contain a lot of leaves require a high concentration of nitrogen.
  • Phosphorus: Plants need phosphorus for root development. It helps anchor the plants in the soil. Phosphorus also increases fruit production and results in a better bloom.
  • Potassium: It fights off diseases and allows the plant to withstand extreme temperatures. Since palm trees are usually grown outdoors, potassium is essential for them.


The NPK ratio of a fertilizer shows the amount of these nutrients present in that blend. Suppose a fertilizer has an NPK ratio of 30-10-10. That means it has 30% nitrogen, 10% phosphorus, and 10% potassium.

Why use the NPK Ratio?

Plants need plenty of nutrients. Why should you choose a fertilizer based on these three nutrients? They are the primary macronutrients.


Plants use up to 17 nutrients to survive. Most of them are micronutrients and are needed in small quantities. Meanwhile, macronutrients are required in higher concentrations.


When looking for the best fertilizer for palm trees, you'll notice that most varieties have more nitrogen than other nutrients. It is due to leaching.


Irrigation and heavy rains remove nitrogen from the soil in a process called leaching. Since nitrogen moves freely, it becomes an easier target than other nutrients.



Fertilizers replenish the lost nitrogen. It is an important component of chlorophyll, the green pigment plants use for photosynthesis. Nitrogen also forms most plant amino acids, which later form proteins.

How to use the NPK Ratio?

To choose palm plant food with the right NPK ratio, you should know your plant's nutrient requirements. A study found that date palm trees need 700 grams of nitrogen for the best growth and fruit quality.


How do you calculate the amount of fertilizer you should look for? Suppose a fertilizer has an NPK ratio of 30-10-30 in a 2lb bag (907 grams).


Since 30% of 907 grams is nitrogen, the fertilizer contains 272 grams of nitrogen. That means you'll need 2.5 bags of this fertilizer to fulfill your plant's nitrogen needs.


700 grams / 272 grams = 2.5 


NPK proves helpful when you have a general idea of the concentration of nutrients your plant needs. You can choose the best fertilizer for palm trees based on this information.



The ideal NPK for palm trees is 3: 1: 3. But you should conduct a soil test to understand the exact NPK needs of your palm.

Inorganic vs. Organic Fertilizer

The debate between organic and inorganic often arises when choosing the best fertilizer for palm trees. Some people may also make a homemade fertilizer using manure, compost, and other organic materials. 



However, it's essential to know the difference between both types of fertilizers. It will help you make an informed decision on which palm plant food to choose.

Organic

Organic fertilizers are made using organic materials. Some of them are:

  • Fish meal
  • Bone meal
  • Compost
  • Manure


Organic fertilizers are generally more expensive than inorganic ones. They also release nutrients slower compared to their quick-release counterparts.


Common examples of organic fertilizers are guano, worm castings, and compost. Some home gardeners may also use seaweed and blood meal fertilizers for palm trees.


The main appeal of these fertilizers is that they are environmentally friendly. They do not contain harmful chemicals that could leach into groundwater or impact the ecosystem. Plus, they are made of renewable resources. This is why some people pick organic for the best fruit tree fertilizers.


It's best to use organic fertilizers on palm trees during the growing season. The general guideline is to apply them every three to four months.


Do note that the palm's growth stage will impact the nutrients it needs. For example, younger plants need more nitrogen since they are growing.


So, you should choose an organic palm fertilizer rich in nitrogen during this stage. Other benefits of using such a fertilizer are:

  • Improvement in soil texture and structure
  • Enhanced nutrient availability and soil fertility
  • Promotion of soil microorganisms
  • Improvement in soil water retention


However, organic fertilizers may smell stinky since they have animal excretions. Only use them for indoor palm trees if you're okay with the smell. Or, buy smell-free alternatives.

Inorganic

Some palm plants require fertilizers rich in micronutrients, such as iron and magnesium. Inorganic fertilizers provide these nutrients that organic fertilizers may not have enough of.

These fertilizers have the following benefits:

  • Quick Results: Since inorganic fertilizers break down quickly, they promptly provide nutrients to plants. They result in the rapid growth of palm trees.
  • Versatility: Inorganic fertilizers are available in different forms. Depending on your preferences, you can buy them as liquids, spikes, or powders.
  • Customizability: Organic fertilizers do not allow customization of nutrient content. They contain only a limited amount of trace elements. In contrast, inorganic fertilizers will enable you to choose the right blend for your plant's needs and soil conditions.
  • Long Shelf Life: While organic fertilizers may clump or spoil fast, inorganic fertilizers have a longer shelf life.
  • Cost-Effectiveness: In general, inorganic fertilizers are cheaper than organic fertilizers. They're ideal for people who need palm fertilizer for a large tree or are on a budget. 


The downsides of using inorganic fertilizers are:

  • Possible Toxic Elements: Some may contain toxic elements, such as formaldehyde. You should read the ingredients before buying an inorganic fertilizer.
  • Environmental Impact: Overusing these fertilizers can cause water and soil pollution. It may harm ecosystems, human health, and wildlife.
  • Soil Health: Inorganic fertilizers may also alter the natural nutrient balance in the soil. It might reduce the soil's ability to support plant growth in the long term.


The best approach to choosing the right palm fertilizer is to consider the type of palm tree, soil conditions, and your budget. It also helps to consult an arborist or a professional gardener for more information.
