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

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
