Product Overview
Description
Wicked Growth 6-0-16 High-Yield Crop Fertilizer is engineered for maximum fruit production in potassium-demanding crops like tomatoes, peppers, melons, squash, and apple trees. This specialized phosphorus-free formula delivers high potassium levels alongside moderate nitrogen, ideal for soils already rich in phosphorus.
The 6-0-16 ratio addresses the specific nutritional demands of fruiting vegetables during their reproductive phase. Established fruiting plants require massive amounts of potassium to transport sugars to developing fruits, maintain cell turgor during hot weather, and resist fungal diseases.
Essential for vegetable gardeners in the Southeast and Gulf Coast regions where summer heat stress demands maximum potassium availability, and equally valuable for greenhouse tomato production where precise nutrient management prevents blossom end rot.
Highlights
• Zero phosphorus for P-rich soils
• High potassium for fruit development
• Prevents blossom end rot in tomatoes
• Ideal mid-season fruiting fertilizer
• Maximizes sugar content & flavor
The Science Behind It
How It Works
This phosphorus-free formula delivers targeted nitrogen and potassium for crops grown in phosphorus-rich soils or during fruit development stages. The 6% nitrogen maintains healthy foliage and photosynthetic capacity, while the high 16% potassium supports fruit quality, disease resistance, and water regulation. Without phosphorus, this blend won't contribute to P buildup in soils already adequately supplied, making it ideal for established plantings and high-yield fruit crops.
The Science
The N-K focus addresses the nutrient demands of fruiting and maturing crops. During fruit fill, plants require substantial potassium to transport sugars from leaves to developing fruit, regulate water content, and maintain cell turgor. Nitrogen sustains chlorophyll production for continued photosynthesis. The absence of phosphorus prevents nutrient imbalances in soils where P levels are adequate or high, avoiding antagonistic effects on micronutrient uptake that excess phosphorus can cause.
Nutrients Available
6% Total Nitrogen – Maintains chlorophyll production and vegetative health during fruiting. 16% Soluble Potash (K₂O) – Enhances fruit quality, sugar content, disease resistance, water efficiency, and post-harvest storage life. Zero phosphorus prevents P buildup in adequately supplied soils.
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
Blossom End Rot Prevention – High potassium improves calcium transport within plants, dramatically reducing blossom end rot in tomatoes, peppers, and squash.
Superior Fruit Flavor – Potassium drives sugar accumulation, producing sweeter tomatoes, more flavorful melons, and peppers with improved color development.
Heat Stress Tolerance – Potassium regulates stomatal function and water balance, helping plants maintain turgor during the hottest summer months.
Targeted Soil Management – Zero phosphorus formula allows precise potassium supplementation without causing nutrient imbalances in P-rich soils.
