Recommended Application Rates for 0-0-60 Fertilizer
The 0-0-60 fertilizer, also known as muriate of potash (potassium chloride), contains 60% potassium (K₂O) and no nitrogen or phosphorus. It supports enzyme activation, water regulation, photosynthesis, and stress resistance, making it ideal for potassium-deficient soils and crops like tomatoes, potatoes, and fruiting plants. Below are recommended application rates to avoid over-fertilization.
Per Square Foot
General Garden Use: Apply 1–2 teaspoons per square foot for lawns and garden beds with potassium deficiency.
High-Potassium Crops: Use up to 3 teaspoons per square foot for crops like tomatoes, potatoes, and root vegetables.
Method: Spread evenly, incorporate into the top 2–3 inches of soil, and water thoroughly to aid nutrient uptake.
Per Plant
Vegetables/Annuals: Apply 1 teaspoon around the base, 2–3 inches from the stem to prevent burn.
Perennials/Shrubs: Use 2–3 teaspoons per plant, distributed around the root zone.
Method: Apply in a circle around the plant, avoiding foliage, and water well.
Per Gallon of Water
Liquid Application: Dissolve 1 teaspoon per gallon of water for container plants or quick potassium boosts.
Method: Apply to soil, avoiding foliage to prevent burn. Use every 4–6 weeks during the growing season.
Application Tips
Soil Testing: Conduct a soil test to confirm potassium deficiency and adjust rates.
Timing: Apply in early spring or before flowering/fruiting; avoid late-season applications to prevent frost damage.
