Palm trees are notorious for the tropical touch they add to a landscape. Though easy to maintain once established, they require adequate sunlight, water, and the proper fertilizer. If these needs aren’t met, a palm tree’s fronds will begin to curl or yellow.
Gardeners can keep fronds lush and green by supplying a fertilizer with a healthy dose of nitrogen and potassium, and a low amount of phosphorus. Palm trees also benefit from micronutrients such as manganese, magnesium, and iron. There are many options to weed through, but we’ve done the work and found some of the best fertilizers for palm trees.

What to Consider When Choosing the Best Fertilizer for Palm Trees
Palm trees require a unique blend of macronutrients and micronutrients to thrive. Gardeners can provide these nutrients through granular, water-soluble, or spike fertilizers. These fertilizers deliver nutrients to the soil, which palm trees can absorb through their root system. Here’s what to look for when choosing the best palm fertilizer.
Type
There are a few forms of palm tree fertilizer, with liquid, water-soluble, granular, and spike being the most common. The difference between them is how they’re applied and how long they work.
- Liquid: Liquid fertilizer comes premixed in concentrated or ready-to-pour containers. Users must dilute concentrated liquid fertilizer with water before adding it to the plant’s soil.
- Water-soluble: Water-soluble fertilizers are highly concentrated and come in a fine powder. The powder is added to water to dissolve before use.
- Granular: Granular fertilizers come in hard pellets that gardeners can work into the soil. Granular fertilizer is typically a slow-release type, providing nutrients to the plant for a longer time than liquid or water-soluble products do.
- Spikes: For gardeners who like to “set it and forget it,” spike fertilizer is the way to go. Place these fertilizer sticks in damp soil around the base of the tree to release nutrients slowly into the soil.
NPK Ratio
Like humans and animals, plants need proper nutrition, and each species has its own requirements. The three macronutrients plants need are nitrogen (N), phosphorous (P), and potassium (K), also known as NPK. Nitrogen helps plants and trees grow green, lush foliage. Phosphorus helps establish a root system and encourages bloom growth in flowering varieties, and potassium improves a plant’s overall health.
On a fertilizer package, these nutrients are listed similarly to this: 10-30-10. Each number represents how much of each nutrient the fertilizer contains, always in the same order (nitrogen-phosphorus-potassium). In this example, the fertilizer has 10 percent nitrogen, 30 percent phosphorus, and 10 percent potassium.
The best food for palm trees is a fertilizer that has a low middle, or phosphorus, number. In addition, the best fertilizer for palms will contain potassium levels equal to or greater than its nitrogen levels. Palm trees also benefit from micronutrients such as magnesium, manganese, and iron.
Organic vs. Inorganic
Aside from the form of fertilizer, gardeners can choose between organic and inorganic products. Though both can deliver the same or similar nutrients to a palm, they have distinctive differences.
Organic fertilizers contain natural ingredients such as minerals from plants, rocks, and animals. These fertilizers are easy for a plant to use and can deliver microorganisms to improve soil quality over time. Most organic fertilizers are nontoxic, making them a top pick for gardeners who have kids and pets.
Inorganic (synthetic, man-made) fertilizers also contain some natural ingredients, such as minerals, that are combined with chemicals to create a highly concentrated product. Because of this process, inorganic fertilizers are less expensive and deliver nutrients quickly. However, they do not last long in the soil or improve its health. They also add to pollution of water bodies and are not as eco-friendly as organic fertilizers, so the best palm tree fertilizer option might depend on personal preference.

How We Chose the Best Fertilizers for Palm Trees
Palm trees are finicky when they don’t receive proper nutrients, causing their fronds to yellow and curl. We considered their unique nutrient needs and looked for fertilizers with higher ratios of nitrogen and potassium rather than phosphorus. This balance of macronutrients helps a palm tree maintain lush green fronds and supports growth.
Once we found products with the proper macronutrient blend, we looked for micronutrient content, ease of use, and price. Next, we narrowed our choices by searching for the best palm tree food in several categories based on price and type of fertilizer. And since palms can grow in containers or in the ground, we looked for options that work in both scenarios.
Tips for Fertilizing Palm Trees
Though palm trees are a relatively low-maintenance plant, they require ample sunlight, water, and the right fertilizer. Palm trees can be planted in the ground or grown in containers. Gardeners who live in areas with colder winters can choose hardy palms that can handle temperatures as low as 10 degrees Fahrenheit or keep their palms in pots, bringing them inside during the winter.
To get the most benefit out of palm tree fertilizer, follow these tips:
- For outdoor palms, fertilize only during the growing season, which is March through October
- Stop fertilizing 2 months before your area’s average frost date
- To prevent potassium deficiencies that can cause fronds to turn yellow, use a fertilizer with potassium equal to or higher than nitrogen.
For indoor palm trees, use a potting soil developed for palms, place your plant in bright light, and water when the soil is dry. After about a month of having the palm indoors, fertilize it following the directions on the product package.
FAQs
Palm trees can be grown anywhere—the key is to pick a suitable variety based on the climate. For example, gardeners who live in areas with cold winters can choose hardy palms, while those who live in warmer regions can grow most types of palm trees. Here are some common palm tree fertilizer questions and their answers to help palm tree growers.
Q. Do palm plants require fertilizers?
Palm trees require fertilizer to keep their fronds from curling and turning yellow. These plants need a low amount of phosphorus compared to the amounts needed for nitrogen and potassium.
Q. Can I use homemade fertilizer for a palm tree?
Many homemade palm tree fertilizer recipes incorporate ingredients such as bone meal, kelp, bat guano, and eggshells. Making your own plant food can provide necessary nutrients if it is customized to a palm tree’s needs.
Q. What kind of fertilizer should I use for palm trees?
Use a fertilizer with low phosphorus and a potassium level equal to or higher than the nitrogen level. Gardeners can choose between granular fertilizer, spikes, and water-soluble powders. If possible, select a fertilizer that also has the key micronutrients of magnesium, manganese, and iron.
Q. How much fertilizer do palm trees need?
The amount of fertilizer a palm needs depends on the tree’s size and the fertilizer type. Slow-release fertilizers can last up to 4 months between applications.
Q. Are coffee grounds good for palm trees?
Coffee grounds increase the soil’s acidity level, which may be beneficial for palms that prefer a higher acidity. However, some palms do better in pH-neutral soil.
Q. Will vinegar kill palm trees?
Vinegar can kill palm trees when repeatedly applied to the root system. Some gardeners use vinegar as a nontoxic way to kill unwanted trees.
