Old Cobblers Farm™ Wicked Growth 0-46-0 Fertilizer – Triple Phosphate

Product Overview

Description

Wicked Growth 0-46-0 Triple Superphosphate delivers the most concentrated phosphorus available in a granular fertilizer, providing 46% available phosphorus to rapidly correct deficiencies and support explosive root growth in transplants, flowering crops, and fruit-bearing plants. This professional-grade formula is the go-to choice for serious gardeners who need maximum phosphorus impact.

Triple superphosphate is manufactured by treating rock phosphate with phosphoric acid, creating a highly concentrated, water-soluble phosphorus source that plants can access immediately after application. This makes it ideal as a starter fertilizer for transplants where rapid root establishment is critical.

Essential for vegetable gardens in the Northeast and Pacific Northwest where cold, wet spring soils limit phosphorus availability, and equally valuable in alkaline soils of the Southwest where phosphorus becomes chemically bound.

Highlights

• 46% Phosphorus – Maximum concentration
• Fast-acting water-soluble formula
• Ideal transplant starter fertilizer
• Corrects deficiency symptoms rapidly
• Professional-grade performance

The Science Behind It

How It Works

Triple superphosphate delivers highly concentrated, water-soluble phosphorus that becomes immediately available to plants upon application. When watered in, the phosphate ions dissolve into the soil solution and are rapidly absorbed by root systems. This fast-acting formula is particularly effective for transplants and establishing new plantings where quick root development is critical. The concentrated 46% phosphorus content means smaller application rates deliver maximum nutrient impact.

The Science

Triple superphosphate is produced by treating rock phosphite with phosphoric acid, creating a highly concentrated, readily available phosphorus source. The high solubility ensures rapid uptake during critical growth phases. Phosphorus directly influences meristematic activity (cell division in growing points), making it essential for root tip elongation, shoot development, and flower bud formation. At the molecular level, phosphorus is incorporated into phospholipids that form cell membranes and nucleic acids that carry genetic information.

Nutrients Available 

46% Available Phosphate (P₂O₅) – Maximum phosphorus concentration for rapid root establishment, accelerated flowering, enhanced fruit and seed production, improved transplant success, and efficient correction of severe phosphorus deficiencies.

How to Apply

1-2 lbs/100 sq ft every 4-6 weeks. Severe deficiency: 2-3 lbs initially.

1

Action:

Survey garden bed and note deficiency symptoms. Map high-need zones.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't leave granules on surface in hot weather - damages plants.

2

Action:

Calculate 1-2 lbs per 100 sq ft. For 10x20 garden (200 sq ft), use 2-4 lbs.

Pro Tip:

Weigh fertilizer on kitchen scale. One cup 0-0-60 weighs ~0.5 lb.

Avoid:

Don't exceed 2 lbs per 100 sq ft per application. Split heavy doses.

3

Action

Broadcast granules evenly across soil surface. Work into top 2-3 inches with cultivator.

Pro Tip:

Sandy areas and fruiting sections need more K than shaded areas.

Avoid:

Don't spread on windy days - granules drift causing uneven application.

4

Action

Water thoroughly with 1-2 inches to dissolve granules and move K into root zone.

Pro Tip:

Incorporation prevents salt buildup and gets K to roots faster.

Avoid:

Don't leave granules on surface in hot weather - damages plants.

Key Benefits

Rapid Root Establishment – Water-soluble phosphorus is immediately available to transplant roots, reducing transplant shock and accelerating establishment.

Maximum Bloom Production – High phosphorus concentration triggers prolific flowering in annuals, perennials, and shrubs, extending bloom periods.

Improved Fruit Set – Phosphorus is essential for flower-to-fruit transition, increasing fruit set percentages in tomatoes, peppers, squash, and tree fruits.

Cold Soil Performance – Highly available phosphorus remains accessible even in cold spring soils where microbial activity is limited.
