Best Fertilizer for Meyer Lemon Trees
Meyer lemon trees require specific nutrients for optimal growth and fruiting. A balanced, high-quality fertilizer helps ensure that your tree remains healthy, produces vibrant leaves, and yields sweet, fragrant fruit. Here’s what you need to know about fertilizing Meyer lemon trees:
Why Choose CompleteGrow Citrus Fertilizer?
Meyer lemon trees thrive when they receive the right mix of nutrients. CompleteGrow Citrus Fertilizer with a NPK ratio of 6-2-12 is specifically designed for citrus plants, offering the perfect balance of nitrogen (N), phosphorus (P), and potassium (K). The high potassium content helps promote flowering and fruit production, while the nitrogen supports strong foliage growth. Our formula also includes essential trace elements like iron, zinc, manganese, boron, and copper to enhance nutrient uptake.
Application Guide:
- When to Apply: Start feeding Meyer lemon trees in early spring when they begin actively growing, and continue every 4-6 weeks throughout the growing season.
- How to Apply: Mix CompleteGrow Citrus Fertilizer according to the instructions on the label. For potted trees, consider diluting the solution to avoid over-fertilizing.
- Why It Works: The balanced NPK formulation ensures your tree gets the nutrients it needs to grow healthy and strong, especially in its early stages of development.
For a more robust and healthy Meyer lemon tree, consider adding CompleteGrow’s Cal-Mag Nutrients Fertilizer during heavy fruiting. This supplement provides essential calcium and magnesium, which are necessary to prevent issues like blossom end rot and ensure the fruit’s overall quality. Apply this after the tree begins fruiting, and continue throughout the fruit development stage for best results.
Why NPK 6-2-12 Works for Meyer Lemons
The NPK 6-2-12 ratio is specifically formulated for citrus trees, where potassium (12%) plays a crucial role in promoting flowering, fruit development, and overall plant health. This high potassium ratio ensures that Meyer lemons not only thrive during their growing period but also set fruit more effectively. The addition of nitrogen (6%) helps support leaf growth, while the phosphorus (2%) ensures a strong root system, creating a solid foundation for future fruiting.


Meyer Lemon Tree Growth and Care Tips
Meyer lemon trees require specific care to thrive and produce fruit. By providing them with the proper environment, regular watering, and fertilization, you can ensure a healthy and productive tree. Here are some key factors for successful Meyer lemon care:
Optimal Growing Conditions for Meyer Lemons
- Sunlight: Meyer lemon trees thrive in full sun. Ensure they receive at least 8-10 hours of direct sunlight each day for optimal growth.
- Temperature: Meyer lemons prefer a temperature range of 15°C to 29°C. They are frost-sensitive, so avoid placing them in areas with freezing temperatures.
- Soil: Well-draining, slightly acidic soil (pH 5.5-6.5) is ideal for Meyer lemons. Ensure good drainage to prevent root rot.
Watering and Maintenance
- Watering: Water deeply once or twice a week during the growing season. Let the soil dry out between waterings to avoid overwatering and root rot.
- Pruning: Regular pruning helps maintain the shape of the tree, improve air circulation, and promote healthy fruit production. Remove dead or damaged branches and prune to maintain a strong structure.
- Mulching: Applying mulch around the base of the tree helps retain moisture and keep the roots cool in hot climates.
