Application Guidelines

When to Apply

• Apply during the mid-season, typically late spring to early summer (May–June), when plants are actively flowering and setting fruit.
• Ensure soil temperatures are between 60°F and 70°F (15°C to 21°C) for optimal nutrient uptake.

How to Apply

• Application Rate:
  • Container Plants: Use 1 tablespoon (15 grams) per gallon of soil (e.g., 5 tablespoons for a 5-gallon pot).
  • In-Ground Plants: Apply 1 cup (240 grams) per mid-sized berry bush, adjusting for plant size.
• Method:
  • Top Dressing: Evenly distribute fertilizer around the plant base, keeping several inches from the stem to avoid nutrient burn.
  • Incorporation: Lightly work into the top 1–2 inches of soil to integrate nutrients and minimize runoff.
  • Watering: Water thoroughly after application to dissolve nutrients and facilitate root uptake.
• Frequency: Reapply every 4–6 weeks during the active growing season, based on plant needs and soil conditions.

Tips for Success

• Soil Temperature: Maintain 60°F–70°F for effective nutrient absorption and root establishment.
• Timing: Apply during active growth to maximize flowering and fruiting.
• Soil Testing: Conduct a soil test to assess nutrient needs and avoid over-fertilization.
• Monitoring: Watch for signs of nutrient deficiency (e.g., yellowing leaves) or excess (e.g., leaf burn) and adjust application as needed.
• Safety: Store fertilizer in a cool, dry place, away from children and pets.
• Avoid Over-Fertilizing: Follow recommended rates to prevent nutrient burn and plant stress.
