🧪 How to Apply

Application Frequency

• Early Spring: First application just before new growth emerges

• Mid-Summer: Second application to support fruit development and post-harvest recovery

Recommended Quantity

• Young Trees (1–3 years): ½–1 lb per inch of trunk diameter

• Mature Trees (4+ years): 1–2 lbs per inch of trunk diameter
  👉 Measure diameter at 4.5 feet above the ground

Steps to Apply

• Clear the Base: Remove any mulch or surface debris from around the tree

• Distribute Evenly: Spread fertilizer in a circle at the tree’s drip line—not directly at the trunk

• Incorporate Lightly: Rake into the top 2–3 inches of soil

• Water Deeply: Soak the root zone to activate nutrients and aid absorption

🌍 Optimal Soil Conditions

• Soil pH: 6.0–7.0 (slightly acidic to neutral is ideal for nutrient uptake)

• Soil Type: Loamy soils that offer a balance of drainage and moisture retention

• Moisture: Keep evenly moist—avoid waterlogged or extremely dry conditions

• Organic Matter: Maintain 3–5% organic content for improved structure and microbial health

• Amendments: For sandy soils, add compost to improve retention; for clay soils, add organic matter to improve drainage

Pro Tip from the Farm:
In colder zones, your tree’s roots are the engine. Focus your feeding on root strength and late-season potassium to build resilience before winter sets in.
