How to Properly Fertilize Citrus Trees


Citrus trees are a beautiful addition to any garden, providing not only beautiful foliage but also delicious fruit. However, to keep your citrus trees healthy and productive, it is important to fertilize them properly.

Although there are certain details that can vary from one citrus to another, that is, it is not exactly the same to fertilize an orange tree as it is to fertilize a lemon tree, the general guidelines do not change. That is why in this article we will talk in a general way about the best ways to fertilize citrus trees.

When to Fertilize Citrus Trees

It is important to fertilize citrus trees during their growing season, which is typically from February to October. During this period, the trees require regular feeding to ensure they have enough nutrients to grow strong and healthy.

What Nutrients Do Citrus Trees Need?

Citrus trees require three main nutrients: nitrogen, phosphorus, and potassium. Nitrogen is important for the growth of leaves and stems, phosphorus promotes root development and fruiting, and potassium helps the tree withstand stress and disease.

Choosing the Right Fertilizer

When choosing a fertilizer for your citrus trees, look for a product that is specifically formulated for citrus trees. These fertilizers will contain the proper balance of nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and magnesium.

How to Apply Fertilizer to Citrus Trees

- Spread the fertilizer evenly around the base of the tree, avoiding contact with the trunk.
- Water the tree thoroughly after applying the fertilizer. This will help the nutrients reach the roots and prevent fertilizer burn.
- Apply fertilizer in small amounts throughout the growing season, rather than all at once. This will provide a steady supply of nutrients to the tree and prevent over-fertilization.

Organic Alternatives to Chemical Fertilizers

If you prefer to use organic fertilizers on your citrus trees, there are several options available:

- Compost: Adding compost to the soil around your citrus trees is an excellent way to provide them with organic nutrients. Compost is rich in nitrogen, phosphorus, and potassium, as well as micronutrients like iron, zinc, and magnesium.

- Fish Emulsion: Fish emulsion is a liquid organic fertilizer made from fish waste. It is high in nitrogen and can be used to fertilize both indoor and outdoor citrus trees.

- Bone Meal: Bone meal is a slow-release organic fertilizer made from ground-up animal bones. It is high in phosphorus and calcium and is ideal for fruiting trees like citrus.

In conclusion, properly fertilizing citrus trees is essential for their health and productivity. By providing them with the right balance of nutrients, you can ensure that they grow strong and produce delicious fruits. Remember to fertilize your trees during their growing season, choose the right fertilizer, and apply it correctly to avoid over-fertilization. Additionally, using organic alternatives to chemical fertilizers can provide you with a more sustainable and eco-friendly way to nourish your trees. Happy gardening!
