Old Cobblers Farm™ Wicked Growth 10-5-13 Fertilizer – High Nitrogen-Phosphate

Product Overview

Description

Wicked Growth 10-5-13 Fertilizer delivers optimized nutrition for fruiting vegetables and berry crops, combining elevated nitrogen for vigorous vegetative growth with strong potassium levels for fruit development and plant resilience. This precision-balanced formula supports plants through every growth stage.

The 10-5-13 ratio reflects the actual nutrient uptake patterns of tomatoes, peppers, strawberries, and other fruiting crops. These plants need sufficient nitrogen to build leaf canopy, moderate phosphorus for root development and flowering, and high potassium to move sugars into fruits.

Developed through extensive field trials with commercial strawberry and tomato growers, this formula delivers the nutrient ratios that maximize both yield and quality in raised beds, containers, and traditional plots.

Highlights

• Optimized for fruiting vegetables
• Balanced N-P-K for complete nutrition
• Strawberry & tomato specialist formula
• Supports vegetative & reproductive growth
• Season-long performance

The Science Behind It

How It Works

This growth-focused blend provides elevated nitrogen for vigorous foliage production, moderate phosphorus for continued root support, and strong potassium for plant resilience. When applied to actively growing plants, nitrogen rapidly stimulates leaf and stem growth, phosphorus maintains root function, and potassium fortifies cell walls against stress. The balanced release supports sustained growth through the season without the boom-bust cycle of high-nitrogen-only fertilizers.

The Science

The 2-1-2.6 ratio approximates the nutrient removal rates of many vegetable and ornamental crops during active growth. Higher nitrogen (10%) drives amino acid synthesis for protein production and chlorophyll formation. Moderate phosphorus (5%) continues supporting ATP energy cycles and nucleic acid production. Elevated potassium (13%) activates enzymes for photosynthesis and maintains osmotic balance. This combination optimizes growth rate while building stress tolerance.

Nutrients Available 

10% Total Nitrogen – Accelerates leaf and stem growth, boosts chlorophyll and protein synthesis. 5% Available Phosphate (P₂O₅) – Sustains root function and energy metabolism. 13% Soluble Potash (K₂O) – Improves drought tolerance, disease resistance, and overall plant vigor during demanding growth phases.

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

Optimized for Strawberries – The 10-5-13 ratio matches strawberry nutrient requirements for maximum runner production, berry size, and sweetness.

Complete Tomato Nutrition – Provides nitrogen for lush foliage, phosphorus for continuous flowering, and potassium for firm, flavorful fruits.

Balanced Growth Promotion – Avoids excessive vegetative growth that delays fruiting while ensuring adequate energy reserves for heavy crop loads.

Disease Resistance Support – Elevated potassium strengthens cell walls and activates plant defense enzymes against early blight and powdery mildew.
