Product Overview
Description
Wicked Growth Deciduous Shrub Fertilizer provides balanced nutrition for shrubs that lose their leaves each fall and must regrow their entire canopy each spring. The 10-10-10 formula supports the full range of deciduous shrub needs.
Deciduous shrubs face unique nutritional challenges. They must build complete leaf canopies each spring, flower at the appropriate time, and then store enough energy in roots and stems to survive winter.
Ideal for mixed shrub borders containing lilacs, forsythias, spireas, and other popular deciduous species that perform reliably year after year.
Highlights
• Balanced seasonal support
• Spring growth emphasis
• Winter hardiness building
• Mixed border compatible
• All deciduous species
The Science Behind It
How It Works
This balanced formula supports deciduous shrubs through their complete annual cycle—spring growth, summer maintenance, and fall preparation for dormancy. Equal proportions of nitrogen, phosphorus, and potassium address all growth phases without biasing toward any single function. Applied in early spring and again after bloom, nutrients support both the current season's display and energy storage for winter survival and strong emergence the following year.
The Science
Deciduous shrubs drop their leaves annually, requiring them to rebuild their entire photosynthetic apparatus each spring from stored reserves. The 1-1-1 ratio supports this cycle by providing nitrogen for rapid spring leaf expansion, phosphorus for the energy metabolism of fast growth, and potassium for building carbohydrate reserves before leaf drop. Balanced nutrition produces dense, well-branched shrubs with good flowering and consistent fall color.
Nutrients Available
10% Total Nitrogen – Fuels spring leaf emergence and summer foliage maintenance. 10% Available Phosphate (P₂O₅) – Supports flowering, root growth, and energy metabolism. 10% Soluble Potash (K₂O) – Builds carbohydrate reserves, winter hardiness, and disease resistance. Ideal for lilacs, forsythias, spireas, and all deciduous landscape shrubs.
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.
