Old Cobblers Farm™ Wicked Growth Strawberry Fertilizer

Product Overview

Description

Wicked Growth Strawberry Fertilizer delivers precision nutrition specifically formulated for maximum berry production, sweetness, and plant health. The 10-5-13 ratio with added sulfur (13%), calcium (3%), and magnesium (3%) addresses the complete nutritional profile strawberries require.

Strawberries have exacting nutritional requirements. They need adequate nitrogen for runner production and leaf development, modest phosphorus for flowering and root health, and high potassium for berry sweetness and disease resistance.

Essential for June-bearing, everbearing, and day-neutral strawberry varieties in matted rows, raised beds, and container systems. The foundation for strawberry patches that produce heavy yields of sweet, picture-perfect berries.

Highlights

• Complete strawberry nutrition
• Added S, Ca, Mg micronutrients
• High K for berry sweetness
• All strawberry types
• Flavor enhancement formula

The Science Behind It

How It Works

This strawberry-specific formula provides elevated nitrogen and potassium with moderate phosphorus to address strawberries' particular nutritional needs. High nitrogen (10%) supports the extensive leaf production strawberries need for photosynthesis and runner development. Elevated potassium (13%) directly improves berry quality, sweetness, and firmness. Included micronutrients address common strawberry deficiencies. Applied at planting and through the season, this formula produces vigorous plants with abundant, flavorful fruit.

The Science

Strawberries have high potassium demands relative to other fruits because potassium directly influences sugar transport to developing berries, affecting sweetness and flavor. The 10-5-13 ratio reflects this priority while providing adequate nitrogen for the extensive foliage strawberries produce and phosphorus for root and crown development. Secondary nutrients (sulfur, calcium, magnesium) address common strawberry micronutrient needs, preventing deficiencies that reduce yield and quality.

Nutrients Available 

10% Total Nitrogen – Drives leaf and runner production. 5% Available Phosphate (P₂O₅) – Supports root and crown development. 13% Soluble Potash (K₂O) – Maximizes berry sweetness, firmness, and flavor. 13% Sulfur, 3% Calcium, 3% Magnesium – Address common strawberry micronutrient requirements for complete plant health.

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

Maximum Berry Sweetness – High potassium (13%) drives sugar accumulation in developing berries for exceptional flavor and eating quality.

Complete Micronutrient Support – Sulfur enhances flavor, calcium prevents tip burn, magnesium powers photosynthesis for sugar production.

Heavy Yield Production – Balanced primary nutrients support abundant flowering and berry development for maximum harvests per plant.

Disease Resistance – Elevated potassium and balanced nutrition produce plants better able to resist leaf diseases and fruit rots.
