Product Overview
Description
Wicked Growth Asparagus Fertilizer is a high-performance formula designed specifically for perennial asparagus beds. With a balanced 16-10-13 nutrient profile and added sulfur (2%), calcium (7%), and magnesium (1%), this premium fertilizer supports vigorous spear development and long-term crown health.
The elevated nitrogen (16%) encourages strong, leafy fern growth after harvest – which is critical for building energy reserves for next year's crop. Phosphorus supports deep root systems and crown structure, while potassium improves disease resistance and overall plant resilience.
Use on newly established asparagus plantings or mature perennial beds to improve spear quality, extend bed productivity, and support reliable harvests year after year.
Highlights
• Optimized formula for asparagus (16-10-13)
• Added Sulfur, Calcium & Magnesium
• Improves spear production
• Supports long-term crown health
• Extended-release nitrogen
The Science Behind It
How It Works
This asparagus-specific formula provides high nitrogen to support the fern growth that builds next year's harvest. Asparagus is a perennial that stores carbohydrates in its crown during summer, then uses those reserves to produce spring spears. Vigorous fern growth is essential for crown health and spear production. Applied after harvest ends, this formula fuels the fern development phase. Included sulfur, calcium, and magnesium address asparagus-specific micronutrient needs.
The Science
Asparagus production depends on crown carbohydrate reserves built during the previous summer's fern growth. The 16% nitrogen drives maximum fern development, creating the photosynthetic capacity needed to store reserves. Phosphorus maintains the crown and root system. Potassium improves winter hardiness and disease resistance. Sulfur is particularly important for asparagus as a component of sulfur-containing amino acids that give asparagus its characteristic flavor.
Nutrients Available
16% Total Nitrogen – Maximizes fern growth for carbohydrate storage. 10% Available Phosphate (P₂O₅) – Maintains crown and root health. 13% Soluble Potash (K₂O) – Builds winter hardiness and disease resistance. 2% Sulfur, 7% Calcium, 1% Magnesium – Address asparagus-specific micronutrient requirements for complete plant nutrition.
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.
