🛠️ How to Apply Old Cobblers Farm™ 15-30-15 Fertilizer

🧰 Materials Needed:

• Old Cobblers Farm™ Ground Flower Fertilizer (15-30-15)

• Measuring cup or scoop

• Gloves (optional)

• Garden trowel or rake

• Watering can or hose with spray nozzle

📆 Frequency of Application:

• Initial Application: Apply at planting or when new growth begins in early spring

• Subsequent Applications: Reapply every 4–6 weeks during the growing season

• Late Season: Avoid late-season feeding to help plants harden off before dormancy

⚖️ Quantity Guidelines:

• Garden Beds: Use 1 tablespoon per square foot of garden space

• Container Plants: Use 1 teaspoon per 6-inch pot; adjust proportionally for larger containers

🌿 Application Method:

• Prepare the Area:

  • Water soil lightly if dry to avoid fertilizer burn

  • Wear gloves if preferred

• Measure and Distribute:

  • Evenly apply to the surface of the soil around the base of the plants

  • Gently rake into the top 1–2 inches of soil

• Water Thoroughly:

  • Use a watering can or hose with a spray nozzle to activate nutrients and carry them to the roots

🌱 Soil Conditions for Maximum Effectiveness

1. Soil pH:

• 6.0 to 7.0 (slightly acidic to neutral) is ideal

• Phosphorus uptake is optimized within this range

• Use lime (to raise pH) or sulfur (to lower pH) as needed based on a soil test

2. Soil Moisture:

• Keep soil consistently moist but not waterlogged

• Ensure containers and garden beds have good drainage

3. Soil Type:

• Loamy soil is best — it balances water retention, drainage, and nutrient holding

• Improve sandy soils with compost

• Amend clay-heavy soil with sand or organic matter for better aeration

4. Organic Matter:

• Add compost, worm castings, or aged manure to boost microbial health and support consistent nutrient absorption

5. Soil Temperature:

• Apply when soil has warmed and plants are actively growing — typically mid-spring to early summer
