Some trees can be grown inside your house or business, such as the kaffir lime tree. However, most citrus trees grow so large that they must be planted outdoors. You may be able to keep the tree inside while it is small, though.
Within the list of citrus trees, you can find many different species. For example, an orange tree can produce navel oranges, blood oranges, or mandarin oranges. It depends on the species that you choose.
The fertilizer you select matters because there are many fertilizers on the market. Make sure that the product shows that it can be used on citrus-producing trees because then you can use it on any citrus tree. The key is to choose the right fertilizer.

The first step is to make sure the product is designed for citrus trees. Once you find a variety of fertilizers that do that, you can choose the one you like best.
It might be best to use the spikes if you are busy and don’t want to walk around spraying each tree. The sprays might be best if you want longevity. Each product is different, so you need to pay close attention to each one’s ability.

Citrus Tree Fertilizer Reviewed
1. Miracle-Gro 1048291 Citrus, Mango, Avocado Shake ‘n Feed Plant Food

The Miracle-Gro Citrus, Mango, Avocado Shake ‘n Feed Plant Food comes in a 4.5-pound container. It offers continuously released plant food. This means you can shake out the recommended amount once, and it feeds the plant for a long time.
This fertilizer comes in a 8-2-10 (nitrogen-phosphate-potash) formulation. Most of the time, fertilizer formulas all include these three numbers, and they always indicate the percentage of those nutrients. It is common for citrus tree fertilizers to have more nitrogen and potash/potassium than phosphate because those nutrients get depleted faster.
You can use this fertilizer on existing and new in-ground citrus trees, as well as mango and avocado trees. It contains more magnesium, potassium, iron, and sulfur. Citrus plants need more of these minerals to prevent nutrient deficiency.
One application of this product can feed your plant up to three months. The continuous release option ensures that you do not burn nor overfeed your plant.
It also makes it easier to feed your plant. You measure out the right amount of food and sprinkle it around the tree. You don’t have to mix anything or guess at the right amount of fertilizer.
2. JR Peters Inc 52524 Jacks Classic Citrus Food Fertilizer

The JR Peters Jack’s Classic Citrus Fertilizer comes in a one-pound bucket with a resealable lid. It comes in the 20-10-20 formulation. It’s designed to give the right combination of nutrients.
It works well on mangos, limes, kumquats, lemons, grapefruits, and oranges. It focuses on enhancing the micronutrient levels of your citrus fruits. That helps you produce stronger branches, more fruit, and greener leaves.
The advanced formulation gives your plant high-quality nutrients. You can deliver more professional-looking results to your garden at home.
Jack’s Citrus feed also helps your plants take in more nutrients. The plant can get nutrients through the leaves and roots.
With the product, you get a pre-measured scoop. Just use one scoop for each gallon of water when it is time to feed. Make sure you know how much water your tree needs to live and grow.
Citrus trees tend to need regular watering when they are new. This can take up to two years.
It’s most helpful to dig a small moat around the tree, usually eight inches from the trunk, and keep it moist. When you fertilize, know how many gallons of water you’ll need and mix up that much food, and then feed your plant.
3. Jobe’s Organics Fruit & Citrus Fertilizer Spikes

When to Fertilize Citrus Trees?
Citrus trees need the right nutrients to grow. They can require a lot of food, so it is important to fertilize them at the right time. That way, you have a healthy tree that bears plenty of fruit.
It is important to fertilize your citrus tree during its active growth period. This is during the summer and spring. It is best to fertilize every one or two months.
Most people also recommend that you fertilize the tree during its dormant period. This is during the winter and fall months, and you should fertilize every two to three months.
It is important to fertilize at the right time to ensure that your citrus tree grows and produces fruit. The winter and fall months should not be skipped. You want the tree to start producing fruit as soon as possible.
If you wait to fertilize until the spring and summer months, your plant is already behind. It is already hungry and trying to grow. Therefore, it might produce blossoms and fruit much later than anticipated.
You also need to know how old the citrus tree is. When the tree gets older, you don’t have to fertilize it during the dormant season. You may also have to fertilize less often during the regular growing season.
You can also use your judgment. If your tree has dark green, lush leaves, you probably don’t need to fertilize. If it doesn’t look healthy or the leaves are yellowing, you should go ahead and fertilize.
How Often to Fertilize Citrus Trees?
Knowing when to fertilize your citrus tree is important. However, you also need to know how often to do it. For new trees, it is important to fertilize regularly.
The problem is that it is easy to over-fertilize your tree. If you do that, it could ‘burn’ the tree and kill it. Therefore, you should read the package directions on your fertilizer for the best results.
When you fertilize and how often is also based on the type of fertilizer you buy. Some fertilizers are designed to last for many months. If your fertilizer is designed to last for three months, you should fertilize every three months like clockwork.
If you over-fertilize, your plant could die. It might get too many nutrients, which could kill it or cause it to go into overdrive.
It might seem like a good idea to over-fertilize. That way, you get more fruit and larger fruits. However, the opposite is usually true – you get less fruit, and it isn’t very big.
How to Fertilize Citrus Trees?
You can fertilize your citrus tree in many ways. You can do it through the roots or the leaves. Many products on the market are designed to do both.
It is important to follow the directions on your fertilizer package. You can find sprayed fertilizers, granules, and spikes.
You will need to know a few things about your tree. For example, you need to know the drip line.
The drip line is from the edge of the leaves to the ground. It is best to sprinkle/spray/insert your fertilizer around the drip line.
Sprays should be diluted. However, you can find sprays that are designed to be sprayed as is. Read the directions on your fertilizer to see how to dilute the liquid.
Granules do not need to be diluted or mixed with anything else. You will read the directions on the package to see how much you need. Usually, a scoop is included; you use however many scoops are necessary for the size of your tree.
Spikes work differently. Everything is pre-measured, so all you have to do is put the cap on the spike and drive it into the ground.
However, you need to establish the drip line first. Insert your spikes about two feet away from the center of the tree or near the drip line. Space the spikes about three feet apart for best results.
Conclusion
You now know that it is important to have good fertilizer for citrus trees. Without it, your tree could get diseased or have yellowed leaves. It might also suffer and not produce fruit as much as it should.
With fertilizer, your trees can look healthier, have greener leaves, and produce more fruit. You will be amazed at what a little work and fertilizer can do. However, it is important to choose the right product.
If you want something organic, you may want to go with Jobe’s products, as they are all organic. The spikes are easy to use and make fertilizing much easier. However, the Jobe’s Organics Fruit & Citrus Fertilizer Spikes are designed for indoor plants.
For larger trees (outside), you may want to consider the Espoma Citrus-tone Plant Food. It is suitable for all types (including indoor trees). It also has similar ingredients.
