Product Overview
Description
Wicked Growth Annual Flower Fertilizer delivers explosive bloom power with a high-phosphorus 15-30-15 formula designed specifically for the intense flowering demands of seasonal annuals. This bloom-boosting formula fuels maximum flower production from spring planting through fall frost.
Annual flowers have one mission: produce as many blooms as possible before frost. This requires massive amounts of phosphorus to support continuous flower bud formation, along with adequate nitrogen for foliage and potassium for bloom longevity.
Essential for petunias, marigolds, impatiens, zinnias, geraniums, and other popular annuals that reward generous feeding with spectacular displays. From window boxes to professional landscapes, this formula delivers season-long color impact.
Highlights
• 30% Phosphorus bloom booster
• Maximum flower production
• Season-long color impact
• Perfect for containers & beds
• Fast-acting formula
The Science Behind It
How It Works
This high-phosphorus bloom booster delivers intense flowering support for annual plants that must complete their entire life cycle in one season. The 1-2-1 ratio prioritizes reproductive development (flowers and seeds) over vegetative growth. Elevated phosphorus drives prolific flower bud formation, while balanced nitrogen and potassium support healthy foliage and bloom longevity. Fast-acting nutrients become available immediately upon watering, supporting the rapid growth rate of annuals.
The Science
Annual flowers invest heavily in reproduction, requiring substantial phosphorus for flower bud differentiation, petal development, and seed formation. The 30% phosphorus concentration supports the ATP-intensive processes of cell division in floral meristems and the transport of sugars to developing blooms. Nitrogen (15%) maintains chlorophyll production for continued photosynthesis, while potassium (15%) regulates water content in petals, extending bloom life and improving flower quality.
Nutrients Available
15% Total Nitrogen – Sustains healthy foliage and photosynthetic capacity. 30% Available Phosphate (P₂O₅) – Maximum flower bud formation, bloom production, and seed set. 15% Soluble Potash (K₂O) – Extends bloom life, improves petal color, and strengthens stems. Ideal for petunias, marigolds, zinnias, impatiens, and all flowering annuals.
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.
