Fertilizing a Lemon Tree: The Complete Guide

The Importance of Fertilizing

Lemon trees are heavy feeders and require regular fertilization to produce abundant fruit. Without adequate nutrients, trees may produce fewer lemons, experience stunted growth, and become more susceptible to pests and diseases.

Ideal Fertilizer for Lemon Trees

The best fertilizer for lemon trees is one that is specifically designed for citrus trees. These fertilizers typically contain a balanced blend of macronutrients (nitrogen, phosphorus, potassium) and micronutrients (calcium, magnesium, iron, zinc). Look for a fertilizer with an NPK ratio of 10-10-10 or 12-12-12.

How to Fertilize Lemon Trees

1. Frequency: Fertilize lemon trees every 4-6 weeks during the growing season (spring and summer).
2. Amount: Apply fertilizer according to the manufacturer's instructions or the following guidelines:
   • Young trees (1-3 years old): 1/4 cup per tree
   • Mature trees (4 years+): 1/2 cup per tree
3. Method: Broadcast the fertilizer evenly around the tree, staying a few inches away from the trunk. Water thoroughly after fertilizing.

Fertilizing Schedule

Tips and Tricks

• Use a chelated fertilizer to ensure that the nutrients are readily available to the tree.
• Water the tree deeply before fertilizing to prevent root burn.
• Avoid over-fertilizing, as this can lead to salt buildup and root damage.
• Test your soil before fertilizing to determine if it is deficient in any nutrients.
• Mulch around the tree to retain moisture and suppress weeds.

Common Mistakes to Avoid

• Fertilizing too often: Over-fertilizing can burn the roots and damage the tree.
• Using the wrong type of fertilizer: Using a fertilizer that is not specifically designed for citrus trees can lead to nutrient deficiencies.
• Applying fertilizer too close to the trunk: This can cause root burn and damage the bark.
• Not watering after fertilizing: Water is essential for the tree to absorb the nutrients.
