Created for gardeners who want bold blooms, lush flowering shrubs, and garden beds that explode in color, this balanced fertilizer blend supports strong roots, vibrant flowers, and sustained flowering throughout the season. If you've searched for “organic flower fertilizer high phosphorus,” “best fertilizer to get more blooms,” or “slow release fertilizer for flowering plants,” 4-6-4 Wicked Organics delivers.

Key Features & Nutrient Balance

Balanced 4-6-4 N-P-K: Higher phosphorus (6) ensures excellent bud formation and flowering, supported by nitrogen (4) for healthy foliage and potassium (4) for robust overall plant health.

Slow-release effect: Nutrients release gradually, reducing risk of burning delicate flowers and producing steady growth rather than fast, weak flushes.

Organic / natural-based ingredients: Enriches soil microbiology and organic matter, improving long-term soil fertility and enhancing root health.

Why It Helps Flowers & Garden Beds

Encourages more flower buds, bigger blooms, and richer color in annuals, perennials, roses, and flowering shrubs.

Supports root strength so plants can draw up nutrients and water more effectively — essential for drought stress, bloom retention, and even flowering.

Helps with disease and pest resistance indirectly by keeping plants healthy and balanced.

Promotes repeat flowering and longer bloom periods by maintaining nutrient supply during peak flowering stages.

Where & How to Use It

Perfect for:

Flower beds, borders, and annual flowering plants

Roses, hydrangeas, azaleas, petunias — any plants where flower appearance matters

Mixed garden beds with perennials & flowering shrubs

Vegetables and fruiting crops during blossom set, when you want to push for fruit and flower production

Pot plant feeding / containers where flowers can fade quickly without adequate nutrition

Application tips:

Apply at planting or just before bloom season begins.

Side-dress or top-dress established flowering plants.

Water in well after application so nutrients move into root zones.

For container plants, gently mix into potting soil near roots (without touching stem base directly).

Proven Benefits from Similar Fertilizers & What Research Shows

Fertilizers with a 4-6-4 ratio like those in Suståne’s 4-6-4 blends help promote healthy root development, improved soil water retention, and more vibrant flowering. 

These fertilizers also increase soil humus/organic matter, which boosts nutrient availability and resilience to stress like drought or heat. 

They are used safely around seed, seedlings, and during delicate growth phases because of their slow-release character, which minimizes risk of leaf burn. 

Key Benefits You’ll See in Your Garden

More vibrant, larger, and longer-lasting blooms

Healthier foliage with deep green leaves to support flowering

Improved soil structure and fertility with time

Better performance of flowering plants under stress (heat, drought, pests)

Less frequent fertilization needed because nutrients feed over weeks
