Old Cobblers Farm™ Wicked Growth Perennial Flowers Fertilizer
Product Overview
Description
Wicked Growth Perennial Flower Fertilizer provides balanced, season-long nutrition that supports the unique growth patterns of plants that return year after year. The classic 10-10-10 formula delivers equal nutrition to maintain healthy foliage, develop strong root systems, and produce reliable blooms.
Perennial flowers have fundamentally different nutritional needs than annuals. Rather than pushing maximum bloom production in a single season, perennials must balance flowering with building root reserves that ensure vigorous return growth next spring.
This balanced formula supports the steady, sustainable growth that keeps perennial borders looking their best for decades, whether maintaining a cottage garden of peonies, a naturalistic planting of coneflowers, or a shade garden of hostas.
Highlights
• Balanced for perennial needs
• Supports winter hardiness
• Builds root reserves
• Steady, sustainable growth
• Season-long feeding
The Science Behind It
How It Works
This balanced formula provides complete nutrition for perennial flowers that return year after year. Unlike annuals, perennials must balance current-season flowering with energy storage for winter survival and next year's growth. Equal proportions of nitrogen, phosphorus, and potassium support this dual purpose—maintaining attractive foliage and blooms while building strong root systems and carbohydrate reserves for dormancy and spring emergence.
The Science
Perennial flowers have different nutritional strategies than annuals. They allocate resources between reproduction (flowers) and survival (roots and storage). The 1-1-1 ratio supports both without biasing toward either. Nitrogen maintains foliage health for photosynthesis. Phosphorus supports both flowering and root carbohydrate storage. Potassium builds cold hardiness by regulating cell osmotic potential and protecting against freeze damage. Balanced feeding produces robust plants that flower reliably for years.
Nutrients Available
10% Total Nitrogen – Supports healthy foliage and gradual growth. 10% Available Phosphate (P₂O₅) – Balances flowering with root development and energy storage. 10% Soluble Potash (K₂O) – Builds winter hardiness, disease resistance, and long-term plant vigor. Formulated for daylilies, hostas, coneflowers, peonies, and all perennial garden flowers.
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.
