🧪 How to Apply

Application Frequency

• Early Spring: At the first sign of new growth

• Mid-Summer: To support flowering and fruit set

• Late Fall: Helps plants store energy before winter dormancy

Recommended Quantity

• Young Trees (<3 years): ½ cup per tree

• Mature Trees: 1 cup per inch of trunk diameter (measured at chest height)

Steps to Apply

• Prepare Soil: Clear the area of weeds and debris

• Check pH: Acid-loving trees thrive in pH 4.5–6.0

• Apply Fertilizer: Distribute evenly around the drip line—never against the trunk

• Loosen Soil: Gently work the fertilizer into the top few inches of soil

• Water Thoroughly: Helps nutrients absorb into the root zone

🌍 Optimal Soil Conditions

• Soil pH: 4.5 – 6.0 (acidic range ideal for nutrient absorption)

• Moisture: Moist but well-draining—avoid soggy conditions

• Soil Type: Loamy or sandy loam soils with high organic content

• Organic Matter: Amend with peat moss, compost, or pine needles to enhance acidity and microbial activity

• Micronutrients: Iron and sulfur levels should be sufficient for chlorophyll production and root health

Pro Tip from the Farm:
For best results, test your soil’s pH annually and adjust as needed using elemental sulfur or peat-based amendments. Healthy roots start with the right foundation—and acid-loving trees demand it.
