SUPER PHOSPHATE 15LB

Give your plants a powerful, concentrated dose of the single most important nutrient for root, bloom, and fruit production: Phosphorus (P). If your garden soil is deficient in phosphorus, this fast-acting supplement ensures strong, deep roots, robust overall plant structure, and greatly improved flower and fruit yield.

• Best For:
  • New Plantings: Essential for mixing into the soil when planting new shrubs, trees, bulbs, and vegetable transplants to promote root establishment.
  • Poor Bloomers: Feeding roses and flowers that produce weak or few buds.
  • Lawn Repair: A non-nitrogen source of phosphorus for establishing grass seed or sod.
• Key Actionable Steps:
  • How to Apply (Mixing): Mix the granules directly into the soil when planting. For planting holes, use 1-2 tablespoons mixed into the bottom and surrounding soil.
  • How to Apply (Established Plants): Apply 2 lbs. per 100 sq. ft. and rake or lightly work the granules into the soil surface around the plant's drip line.
  • Water In: Water thoroughly after application to help move the phosphorus down to the root zone, where it is absorbed.
  • Pro Tip: Phosphorus does not move through the soil easily, which is why it's most effective when mixed directly into the soil profile during planting. Apply in the fall to encourage root development over the winter.
