What fertilizer to use on Citrus trees?

You will discover numerous varieties of Citrus trees. The most common Citrus trees are oranges, grapefruit, lemons, and limes. You must search for information on how those trees bloom and produce fruit. It is vital information about when these trees bloom and when to plant.

Fertilizer for the Lemon tree should be high in nitrogen or nitrogenous fertilizers. Nitrogen for lemon trees is very important. The formula should not have any number higher than 8 (nitrogen-phosphate-potash).

The Lemon tree soil pH should be between 5.5 and 6.5. If the Lemon tree soil pH is above 7.0, can cause nutritional deficiencies that can stunt the Lemon trees’ growth.

Orange trees tend to grow with the best result with a balanced fertilizer or one higher in nitrogen (nitrogen, phosphorus, and potassium). It also requires micronutrients iron, manganese, and zinc for the best optimum growth.

Best result

To achieve the best result for the Orange tree, look for a fertilizer ratio no higher than 8-8-8 just like a Lemon tree. It would be a great Orange tree food.

While the Grapefruit, you have to make sure to keep the soil pH more acidic, like 6.0 to 6.5. You have to test the soil pH before planting and add dolomite limestone to raise the pH if it is essential. If the pH is high, you can solve this by adding sulfur to lower the pH. You have to purchase soil test kits.

Fertilize the Grapefruit trees 3 times in one year with a Citrus fertilizer. Add more Nitrogen in a warmer climate. To produce a better result, make sure to test the soil of the Grapefruit tree that has the nutrients it needs. You can utilize home soil tests and citrus care kits.

Citrus trees can be grown indoors or in the office, such as the Kaffir lime tree. But many of them will grow very large, so they can only grow outdoors.

Type of citrus tree

There are many different species of Citrus trees. An orange tree can produce mandarin oranges, navel oranges, and blood oranges.

While Grapefruits have popular varieties including White Grapefruit, Pink Grapefruit, and Ruby Red Grapefruit. They do not have the same degrees of seeds and sweetness. They come in many varieties determined by color.

The lemon tree also has many varieties. Meyer lemon trees is a common one that can produce large volumes of fruit year-round. The taste of the fruits is juicy, sweet, and thin in the skin.

The good thing about this Lemon is that it is less acidic than other lemons. Eureka Lemons are the kind of Lemon that can be easily found in your nearest grocery store. The taste is juicy and tart.

The best result of tree production has a lot to do with the fertilizer you select. Ensure the fertilizer product shows that it can be used on any Citrus trees or as Citrus fruit tree fertilizer.

There are many options available. You can use spikes or sprays or a mixture that holds all the nutrients needed. As well as traditional and organic mixtures. The early stage is to make sure the fertilizer product is designed specifically for Citrus trees or as Citrus fruit tree fertilizer.

What is the best time to fertilize a Citrus tree?

Citrus trees require a certain amount of nutrients to grow well. They are heavy feeders. Fertilizing citrus trees is very essential in order to have a healthy and fruit-bearing Citrus tree.

By studying the proper knowledge on how to fertilize Citrus plants or Citrus fruit trees can make the difference between a bumper or a bumper crop of fruit.

The best time to fertilize a Citrus tree is during the active growth of Citrus plants. You need to fertilize one time every one to two months and during the spring and summer months. While during the months of fall and winter, fertilize the tree one time every two to three months (dormant period).

Mature stage

During the mature stage of the tree, you can eliminate the plan to fertilize during fall and winter. Increase the amount of time between active growth fertilizing to one time every two to three months.

To know the best time frames of the fertilizing activities for your tree, see the physical appearance and growth. If a Citrus tree looks dark green, looks lush, and is holding onto fruit, this means you do not need to fertilize the tree as often.

With its healthy appearance, but you fertilize it too often would cause the Citrus plants to produce inferior fruit. When Citrus bloom, it is the most nutrient hungry stage until they have firmly set fruit.

If it does, ensure to apply Citrus fruit tree fertilizer regardless of health. This will ensure Citrus plants has enough nutrients to properly produce fruit.

How to Fertilize a Citrus Fruit Tree Or Citrus Plants?

The first kind of fertilizing Citrus tree is done through its leaves. The second kind of fertilizing Citrus plants is through the ground.

When you already purchase one Citrus tree fertilizer product, read and follow the instruction label on how to fertilize using the product.

The directions will be to either spray the fertilizer onto the leaves of your citrus tree or spread it out around the soil of the tree. You have to remember not to place the fertilizer near the trunk of the tree.

You can search for sprayed fertilizers, granules, and spikes. It is recommended to have the best result to sprinkle or spray or insert your fertilizer around the drip line or from the edge of the leaves to the ground.


If you buy sprayed fertilizer, it must be diluted. But there are sprays that are designed to be sprayed for an easy to use fertilizer. Always read the instruction label or directions on your chosen sprayed fertilizer to see how to dilute the liquid.

If you purchase granules fertilizer, you do not require to dilute or mix them with anything else. As always, just read and follow the directions on the package.

Look for the information on how you need it. A scoop is usually included for measuring. Use them as necessary for the size of your tree.

If you choose spikes fertilizer, it would be different. The application is pre-measured. It is easy to apply.

You just have to put the cap on the spike and drive it into the ground. Before that, you need to establish the drip line first. Insert your spikes at about two feet away from the center of the tree.

Or you can insert near the drip line. Make a space about three feet apart between spikes. This will give you the best results.

What kind of Citrus fruit tree fertilizer require?

All Citrus plants or trees like an Orange tree, Lemon tree, and mature or young Grapefruit tree will receive benefit from a nitrogen-rich fertilizer or source of Nitrogen or balanced NPK fertilizer.

This fertilizer must have some micronutrients in it including magnesium, manganese, iron, copper, zinc, and boron.

Magnesium forces the movement of carbohydrates from leaves to other parts of the Citrus tree. Seedy Citrus plant varieties may need more Magnesium than seedless ones.


The manganese is involved with photosynthesis, efficient use of Nitrogen, protein metabolism and enzyme activation. Manganese will increase yields when applied on both soil application and foliar sprays.

Iron, manganese and zinc deficiencies usually appear together as lighter splotches between the veins of a leaf.

Boron is involved in many enzyme systems, in carbohydrate metabolism and translocation. It works like calcium that has an important role in cell structure and cell wall integrity.
