In this experiment, urea foliar fertilizer was applied to ‘Ellis Bitter’ and ‘Harry Masters Jersey’ apple trees to create Control (0 applications), Low (3 weekly applications), and High (5 weekly applications) treatments.

2、Foliar Mn and Zn Treatments Improve Apple Tree Nutrition and Help to

The foliar application of micronutrients can improve primary nutrient uptake. As a result, foliar treatments can reduce fertilizer application rates and help to maintain the natural health of soil.

In this report, we focus on the principles of foliar nutrient uptake and impacts of foliar urea and Ca sprays on fruit quality attributes of ‘Fuji’ apples (Malus domestica). Based on our studies, a ground application of urea is critical for a higher production of ‘Fuji’ apple.

Spray Schedule for Home Apple Trees

Often the product label will direct to spray at certain developmental stages in the tree’s annual growth cycle. Many of the most effective management steps occur in spring, well before the apples form and ripen.

Foliar fertilization is a common practice in fruit tree management, where nutrients are directly absorbed by spraying diluted fertilizer solutions onto plant leaves. For apple trees, applying foliar fertilizer not only enhances fruit quality but also promotes healthy growth and development. Below is a detailed guide on how to properly use foliar fertilizer for apple trees:

1. Choose the Appropriate Foliar Fertilizer

• Type of Fertilizer: Select fertilizers based on the tree’s nutritional needs. Common options include nitrogen (N), phosphorus (P), and potassium (K) formulations. Soil test results and the tree’s growth stage should guide your choice.
• Concentration: Dilute the fertilizer to avoid damage. A typical ratio is 500:1 to 1000:1 (fertilizer:water). High concentrations may harm the trees.

2. Prepare the Necessary Tools and Materials

• Sprayer: Use a fine-mist sprayer with a filter to prevent clogging.
• Water: Clean water for dilution (e.g., a 1:1000 ratio of fertilizer to water).
• Safety Gear: Wear masks, gloves, and protective clothing to avoid direct contact with chemicals.

3. Timing and Application Methods

• Optimal Timing: Apply in the morning or evening when temperatures are cool to reduce evaporation and improve absorption.
• Even Coverage: Spray uniformly across all leaves, avoiding over-concentration on single areas to prevent leaf burn.
• Dosage: Adjust based on tree size. A general guideline is 50–100 milliliters (mL) per tree per application.

4. Key Considerations

• Monitor Reactions: Observe the trees after application. Discontinue use immediately if adverse effects occur (e.g., wilting, leaf discoloration).
• Avoid Overuse: Excessive spraying wastes resources and may damage the trees.
• Balanced Formulations: Tailor nutrient ratios to the tree’s specific needs for optimal results.

5. Post-Application Care

• Watering: Follow up with irrigation to help nutrients penetrate leaves.
• Growth Observation: Regularly check the trees’ health. Repeat applications as needed to boost growth and fruit quality.

Foliar spraying is an efficient and effective method to nourish apple trees. When used correctly, it improves fruit quality and supports healthy tree development. careful attention to dosage, timing, and safety protocols ensures the best outcomes. By following these guidelines, you can maximize the benefits of foliar fertilization for your apple orchard.
