Triple Phosphate Guide

Recommended Application Rate (per sqft, per plant, per gallon of water)

Triple Phosphate, also known as Triple Superphosphate, is a highly concentrated phosphorus fertilizer with an NPK ratio of 0-46-0. It is primarily used to boost phosphorus levels in the soil, which is essential for root development, flowering, and fruiting in plants. Here’s a detailed guide on the recommended application rates for Triple Phosphate:

Application Rate per Square Foot

1. Initial Soil Preparation:

   • Before planting, incorporate the fertilizer into the soil. Use approximately 0.5 to 1.0 ounce (about 1 to 2 tablespoons) of Triple Phosphate per 10 square feet of garden area.

   • This rate is suitable for most vegetable gardens, flower beds, and general landscaping. Work the fertilizer into the top 6 inches of soil for even distribution.

2. Side Dressing During Growth:

   • For crops with high phosphorus needs, such as root vegetables or flowering plants, apply a side dressing of about 0.5 ounces per 10 square feet every 4-6 weeks.

   • Ensure the fertilizer is applied a few inches away from the base of the plants to avoid direct contact with the roots.

Application Rate per Plant

1. At Planting:

   • For small plants or seedlings, mix about 0.5 teaspoon of Triple Phosphate into the soil at the bottom of each planting hole.

   • Ensure the fertilizer is well-mixed with the soil to prevent root burn.

2. During Growth:

   • For larger plants or shrubs, apply 1 to 2 teaspoons per plant every 4-6 weeks as a side dressing.

   • Spread the fertilizer in a circle around the plant, keeping it at least 3 inches away from the stem to avoid direct contact.

Application Rate per Gallon of Water

1. Liquid Fertilizer Solution:

   • Triple Phosphate is not highly water-soluble, so it is not commonly used in liquid form. However, for a phosphorus-rich solution, dissolve about 0.5 tablespoon in 1 gallon of water with agitation, as it may not fully dissolve.

   • Use this solution to water plants every 4-6 weeks, ensuring thorough coverage of the root zone.

2. Foliar Feeding (Optional):

   • For foliar feeding, use a highly diluted solution of 0.25 teaspoon per gallon of water, ensuring filtration to avoid clogging.

   • Apply as a fine mist to leaves in early morning or late afternoon to avoid leaf burn.

Additional Tips

• Soil Testing: Before applying any fertilizer, it’s beneficial to conduct a soil test to determine existing nutrient levels and adjust the application rate accordingly.

• Watering: Always water the plants thoroughly after applying granular fertilizer to help dissolve the nutrients and prevent root burn.
