Old Cobblers Farm™ Wicked Growth Garlic + Onion Fertilizer

Product Overview

Description

Wicked Growth Garlic & Onion Fertilizer provides balanced nutrition for allium crops that form bulbs underground while displaying leafy tops above. The 10-10-10 formula supports the complete nutritional needs from planting through harvest and curing.

Alliums have extended growing seasons that demand consistent nutrition. They need nitrogen for the lush green tops that power photosynthesis and bulb development, phosphorus for root establishment and bulb initiation, and potassium for bulb density, flavor, and storage quality.

Essential for fall-planted garlic, spring onion sets, and the full range of allium crops. Grows the big, flavorful bulbs that make homegrown alliums worth the effort.

Highlights

• Complete allium nutrition
• Supports bulb development
• Improves storage quality
• All allium types
• Season-long feeding

The Science Behind It

How It Works

This allium-specific formula provides balanced nutrition for garlic, onions, and related crops throughout their growth cycle. Equal proportions of NPK support both the green top growth these crops need for photosynthesis and the bulb development that represents the harvest. Applied at planting and during active growth, nutrients support the transition from vegetative growth to bulb formation that determines final bulb size.

The Science

Alliums store photosynthates in bulb scales, making leaf development critical for bulb size—more leaves mean more solar energy captured and stored. Nitrogen drives this leaf production. Phosphorus supports root development in these shallow-rooted crops. Potassium influences bulb quality by regulating the transport and storage of sugars. The balanced ratio supports all phases of the allium growth cycle without biasing toward excessive top growth or premature bulbing.

Nutrients Available 

10% Total Nitrogen – Fuels abundant leaf growth for maximum photosynthesis. 10% Available Phosphate (P₂O₅) – Supports root development and early bulb initiation. 10% Soluble Potash (K₂O) – Enhances bulb size, storage quality, and disease resistance. Balanced nutrition for garlic, onions, shallots, and all allium family crops.

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

Large Bulb Production – Balanced NPK supports the full development of large, uniform bulbs with dense, tight clove structure.

Flavor Enhancement – Complete nutrition produces the strong, complex flavors that distinguish homegrown garlic and onions.

Storage Quality – Adequate potassium improves bulb density and reduces moisture content for extended storage.

Green Top Vigor – Sufficient nitrogen maintains the healthy green tops that power photosynthesis and bulb filling.
