How to fertilized citrus tree such as lemon or orange tree?

 

Fertilizing citrus trees, such as lemon or orange trees, is important to provide them with the necessary nutrients for healthy growth and optimal fruit production. Here are some guidelines on how to fertilize citrus trees effectively:

1. Timing: Citrus trees benefit from regular fertilization during the growing season. Start fertilizing in early spring, just as new growth begins, and continue through the summer. Avoid fertilizing in late fall and winter when the tree is dormant.

2. Choose the Right Fertilizer: Use a balanced fertilizer specifically formulated for citrus trees. Look for a fertilizer with an N-P-K ratio (nitrogen, phosphorus, potassium) of approximately 2:1:1 or 3:1:1. Citrus-specific fertilizers usually contain essential micronutrients like iron, manganese, zinc, and others that citrus trees require.

3. Application Method: Apply the fertilizer evenly over the soil surface within the tree's drip line (the area beneath the outermost branches). Avoid placing the fertilizer directly against the trunk. Spread the granules or apply liquid fertilizer according to the package instructions.

4. Fertilizer Amount: Follow the package instructions for the recommended dosage based on the age and size of your citrus tree. As a general guideline, for mature citrus trees, apply approximately 1 pound (0.5 kg) of fertilizer per year of tree age, up to a maximum of 10 pounds (4.5 kg) per application. Split the total amount into multiple applications throughout the growing season.

5. Watering: After applying the fertilizer, water the tree thoroughly. Water helps to dissolve and distribute the fertilizer into the root zone. Ensure that the soil is adequately moist but not waterlogged. Maintain regular watering practices throughout the growing season.

6. Avoid Over-Fertilization: Over-fertilization can lead to excessive foliage growth at the expense of fruit production and can even harm the tree. Always follow the recommended dosage and avoid applying more fertilizer than necessary.

7. Organic Fertilizer Options: If you prefer organic fertilizers, you can use well-composted manure, compost, or organic citrus tree fertilizers. Follow the package instructions for application rates and methods.

8. Additional Micronutrient Applications: Citrus trees may benefit from supplemental micronutrient applications, especially in soils with known deficiencies. Iron deficiency, indicated by yellowing leaves with green veins (chlorosis), is a common issue in citrus trees. If necessary, apply chelated iron or other micronutrient sprays according to the package instructions.

9. Observing the Tree: Pay attention to the tree's growth and appearance. If you notice signs of nutrient deficiency, such as yellowing leaves or stunted growth, consider adjusting your fertilization program or consulting a local horticulturist or extension service for further guidance.

Remember, healthy soil conditions, proper watering practices, and appropriate fertilization all contribute to the overall health and fruit production of citrus trees. Regular and consistent fertilization, along with other essential care practices, will help your lemon or orange tree thrive and produce delicious fruits.
