Product Overview

Description

Wicked Growth Bonsai Fertilizer provides the precise, balanced nutrition miniature trees require for controlled growth, refined branch structure, and long-term health. The 10-10-10 formula supports all bonsai species with complete nutrition that maintains vigor without overstimulating growth.

Bonsai cultivation is the art of maintaining tree health while restricting growth to artistic proportions. This requires balanced nutrition that keeps trees vigorous enough to survive container culture stresses while not promoting rapid growth that overwhelms careful training.

Essential for juniper, ficus, elm, maple, and all other bonsai species. Provides the nutritional foundation that keeps these living sculptures healthy and beautiful for decades.

Highlights

• Balanced for controlled growth
• All bonsai species safe
• Supports long-term health
• Container culture optimized
• Refined branch development

The Science Behind It

How It Works

This balanced formula provides complete nutrition for bonsai trees maintained in miniature form. Bonsai culture requires controlling growth while maintaining plant health—balanced nutrition supports this by providing adequate but not excessive nutrients. The 10-10-10 ratio feeds root, trunk, and foliage development proportionally, supporting the refined growth patterns that bonsai aesthetics require. Applied frequently in small amounts during the growing season, this formula maintains vigor without promoting coarse, vigorous growth.

The Science

Bonsai trees are genetically full-size trees maintained in miniature through cultural practices including careful nutrition management. Balanced, moderate fertility produces the fine branching, small leaves, and controlled internode length that define bonsai aesthetics. Nitrogen supports leaf production and trunk thickening. Phosphorus maintains the extensive root systems packed into small containers. Potassium builds resistance to the stress of constant pruning and root confinement. The art requires feeding for health without feeding for maximum growth.

Nutrients Available 

10% Total Nitrogen – Supports controlled growth and proper leaf development. 10% Available Phosphate (P₂O₅) – Maintains root health in confined containers. 10% Soluble Potash (K₂O) – Builds stress tolerance and supports bark development. Balanced formula for juniper, maple, pine, ficus, and all bonsai species across deciduous and evergreen types.

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
