Product Overview
Description
Wicked Growth Seed Potato Fertilizer delivers the high-phosphorus, high-potassium nutrition that potatoes require for maximum tuber production, uniform sizing, and excellent storage quality. The 8-16-16 formula emphasizes root and tuber development over foliage growth.
Potatoes have specific nutritional requirements. Excessive nitrogen produces lush vines but delays tuber formation, reduces specific gravity, and increases disease susceptibility. This formula's conservative nitrogen with double P-K produces tuber-focused growth.
Essential for home potato patches and commercial potato production. The tuber-building formula trusted by growers who measure success by what's underground.
Highlights
• High P-K for tuber development
• Low N prevents excess foliage
• Improves storage quality
• All potato varieties
• Professional-grade results
The Science Behind It
How It Works
This potato-specific formula provides moderate nitrogen with doubled phosphorus and potassium to support tuber development over vine growth. Potatoes need extensive root systems to support the heavy tuber loads they produce, requiring substantial phosphorus. High potassium directly improves tuber size, starch content, and storage quality. Applied at planting and hilling, nutrients support early establishment and tuber bulking through the season.
The Science
Potato nutrition must balance vine growth (photosynthetic capacity) with tuber development (harvest yield). Excess nitrogen produces excessive vines that delay tuber initiation and reduce yields. The 8-16-16 ratio provides adequate nitrogen for canopy development while prioritizing the phosphorus and potassium tubers require. Phosphorus supports the rapid root development potatoes need for water and nutrient access. Potassium activates starch synthase enzymes, directly affecting tuber size and quality.
Nutrients Available
8% Total Nitrogen – Supports adequate vine development without delaying tuber set. 16% Available Phosphate (P₂O₅) – Drives root development and early tuber formation. 16% Soluble Potash (K₂O) – Maximizes tuber size, starch content, and storage quality. Formulated for seed potatoes and all potato varieties.
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 Tuber Yield – High phosphorus and potassium direct plant energy into tuber production rather than excessive vine growth.
Uniform Tuber Sizing – Balanced nutrition produces the consistent tuber sizes that growers prefer.
Superior Storage Quality – High potassium reduces tuber moisture content and strengthens cell walls for longer storage life.
Disease Resistance – Lower nitrogen produces tougher plants less susceptible to late blight and soft rot diseases.
