Hi-Yield® Triple Super Phosphate

Hi-Yield® Triple Super Phosphate delivers concentrated phosphorus — the essential nutrient responsible for root development, bloom production, and fruit and bud set — to vegetables, shrubs, flowers, shade trees, and fruit trees. Where nitrogen drives leafy growth and potassium supports overall plant health, phosphorus is the nutrient that drives what you’re actually growing for: stronger roots, more blooms, and better fruit set. Apply in early spring before growth begins or in fall after leaves drop for best uptake.

Why Phosphorus Matters — Roots, Blooms, and Fruit Set

Phosphorus plays three critical roles in plant development that no other nutrient can replace. It builds the strong, deep root systems that anchor plants and access water and nutrients efficiently. It drives the flowering response that leads to fruit and seed production — which is why phosphorus applications consistently improve bloom production and fruit set in fruit trees and flowering plants. And it strengthens the bud and fruit development that determines yield quality. If your plants are producing fewer flowers, setting less fruit, or establishing slowly from transplant, phosphorus deficiency is often the cause.

Broad Application Across the Entire Garden

Triple Super Phosphate works across every category of garden plant. For fruit trees and shade trees, apply evenly beneath and slightly beyond the branch spread in early spring before growth begins or in fall after leaves drop. For shrubs and flowers, apply in early spring and again in summer, side-dressing around mature plants and working lightly into the soil. For vegetables, incorporate into the soil before planting and side-dress after seeding.

Always read and follow label directions for specific application rates and timing.
