FEATURES

🌹 Bloom-Focused 4-7-5 NPK Ratio

Higher phosphorus (7%) specifically targets bud formation and flower size, while moderate nitrogen (4%) prevents leggy, flowerless growth common with balanced formulas.

🦠 Feeds Soil Biology, Not Just Plants

Unlike synthetic salts, organic meals feed earthworms, mycorrhizae, and beneficial microbes that build long-term soil health and improve nutrient cycling season after season.

🐾 Slow-Release & Burn-Free

Won't burn roots or shock transplants. Nutrients release gradually over 4–6 weeks as soil microbes break down organic matter, providing steady, gentle feeding.

🌋 70+ Trace Minerals from Azomite

Volcanic ash provides micronutrients most soils lack—enhancing flower color, fragrance, disease resistance, and overall plant vigor beyond what NPK alone delivers.

🌾 Triacontanol Growth Stimulant

Alfalfa meal contributes triacontanol, a natural plant growth hormone prized by rose growers for boosting bloom count and accelerating new cane development.

🦴 Dual Phosphorus Sources

Both fish bone meal and bone meal provide phosphorus at different release rates, delivering immediate bloom support plus sustained flowering throughout the season.

🍅 Versatile for Flowering Vegetables

Excellent for tomatoes, peppers, squash, and cucumbers. The high calcium from bone meal also helps prevent blossom end rot in fruiting crops.

🌊 Natural Cytokinins from Kelp

Kelp meal provides natural growth hormones, micronutrients, and cytokinins that boost stress resistance, root development, and plant vigor during heat and drought.

🧪 Tested for Heavy Metals

Every batch is independently lab tested for heavy metal content and registered with the California Department of Food and Agriculture (CDFA) for quality assurance.

🌿 OMRI-Listed Organic Ingredients

All ingredients are sourced from OMRI-listed organic materials, making this formula safe for organic gardens and certified organic growing operations.

DERIVED FROM
SCIENCE BEHIND THE FORMULA

4-7-5: Engineered for Maximum Bloom Production

This NPK ratio was specifically designed to prioritize flower bud formation (phosphorus-dominant) while providing enough nitrogen for healthy foliage and potassium for disease resistance. The result is a formula that produces more blooms, deeper colors, and stronger plants.

🌿 Nitrogen — 4% (Gentle Foliage Support)

Kept intentionally low to prevent the leggy, flowerless growth that excess nitrogen causes in roses and flowering plants. Slow-release from feather meal and alfalfa meal ensures steady greening without growth spurts.

🌸 Phosphorus — 7% (The Bloom Nutrient)

The dominant nutrient in this formula. Phosphorus triggers flower bud initiation, develops strong root systems, and intensifies petal colors. Sourced from both fish bone meal and bone meal for multi-rate release.

⭐ Potassium — 5% (Disease & Stress Resistance)

Strengthens cell walls and stems, improves drought tolerance, and enhances winter hardiness. Derived from alfalfa meal and kelp meal for organic, slow-release delivery.

Trace Mineral Profile

🌋 Azomite® — 70+ Minerals

Ancient volcanic ash providing iron, manganese, zinc, copper, boron, and dozens more trace elements. Fills micronutrient gaps that most soils develop over time.

🌊 Kelp Meal — 60+ Minerals

Ocean-sourced trace minerals plus natural cytokinins and auxins that promote cell division, root growth, and stress tolerance during heat and drought.

🦴 Bone Meal — Calcium 24%

Significant calcium contribution strengthens cell walls, prevents blossom end rot in tomatoes and peppers, and supports strong stem and cane development in roses.

Why High Phosphorus?

🌹 More Blooms Per Plant

Phosphorus triggers the hormonal signals that initiate flower bud formation. Higher phosphorus means more buds set per branch, resulting in fuller, more abundant bloom displays.

🎨 Deeper, More Vivid Petal Colors

Adequate phosphorus intensifies anthocyanin pigmentation in petals, producing richer reds, deeper pinks, and more saturated purples in roses and flowering plants.

🌱 Stronger Root Systems

Phosphorus is essential for root cell division and energy transfer. Plants with strong phosphorus nutrition develop deeper, more extensive root networks that improve water and nutrient uptake.

🔄 Faster Rebloom Cycles

Repeat-blooming roses and perennials recover faster between bloom cycles when phosphorus is readily available, shortening the gap between flushes of flowers.

APPLICATION RATES & DIRECTIONS

Application Rates by Planting Type

Application Type Rate Instructions
Garden Beds ¼ cup (4 tbsp) per sq ft Work into top 2–3" of soil, water thoroughly
Potted Plants ¼ cup per gallon of soil Mix into potting medium before planting
Established Roses ½–1 cup per bush Scratch into soil around drip line, water in
New Plantings ½ cup per planting hole Mix with backfill soil, plant, then water
Top Dressing 2–3 tbsp per plant Apply around base, cover with mulch
📦 Package Reference: 1 pound ≈ 2 cups. A 5 lb bag covers about 40 square feet of garden bed per application.

Fertilizing Schedule

Season Timing Notes
Early Spring When new growth appears First feeding of the season — feeds spring flush
Late Spring After first bloom cycle Supports summer reblooming
Mid-Summer July (warm climates) Optional boost for repeat bloomers
Late Summer August–September Final feeding — builds roots for winter
💡 Application Tip: For established plants, scratch fertilizer into the top 2" of soil around the drip line (outer edge of plant canopy), then water deeply. This prevents crusting and delivers nutrients directly to feeder roots.
HOW TO USE

Garden Beds & In-Ground Planting

  1. Measure the appropriate amount based on area (¼ cup per sq ft for beds, ½–1 cup per rose bush).
  2. For new plantings, mix fertilizer into the backfill soil before placing the plant in the hole.
  3. For established plants, scratch fertilizer into the top 2–3 inches of soil around the drip line using a hand cultivator.
  4. Water deeply after application to activate microbial breakdown and prevent surface crusting.
  5. Reapply every 4–6 weeks during the growing season, following the seasonal schedule above.

Container & Potted Plants

  1. Mix ¼ cup of fertilizer per gallon of potting soil before planting.
  2. For existing container plants, sprinkle 2–3 tablespoons on the soil surface.
  3. Gently work into the top inch of soil with a fork, being careful not to disturb roots.
  4. Water thoroughly until water drains from the bottom of the container.
  5. Reapply every 4–6 weeks. Container plants may benefit from slightly more frequent feeding since nutrients leach with watering.

Top Dressing & Side Dressing

  1. Apply 2–3 tablespoons around the base of each plant, keeping fertilizer 2–3 inches away from stems.
  2. Cover the fertilizer with a thin layer of mulch (1–2 inches) to retain moisture and accelerate breakdown.
  3. Water gently to settle the fertilizer into the mulch layer.
  4. This method works well for mid-season feeding of established perennials and shrubs.
💡 Pro Tip: The high calcium content from bone meal helps prevent blossom end rot in tomatoes and peppers. This formula works double-duty in vegetable gardens where you want both beautiful flowers and healthy fruit set.

FREQUENTLY ASKED QUESTIONS
Will this fertilizer burn my plants?

No. Unlike synthetic "blue powder" fertilizers that can chemically burn roots, this is a slow-release organic formula. Nutrients become available gradually as soil microbes break down the organic matter over 4–6 weeks. It's safe for even delicate transplants when used as directed.

Can I use this on vegetables?

Absolutely! This formula is excellent for flowering vegetables like tomatoes, peppers, eggplant, squash, and cucumbers—any crop that needs blooms to produce fruit. The high calcium content from bone meal also helps prevent blossom end rot. For a deeper dive into choosing fertilizers for your vegetable garden, see our guide on What Types of Fertilizers Should I Use to Improve Fruit Yield?

For leafy greens (lettuce, spinach, kale), you may want a higher-nitrogen fertilizer like Blood Meal 13-0-0 instead.

Why are my rose leaves turning yellow?

Yellowing leaves (chlorosis) often indicate nitrogen deficiency, iron deficiency, or pH imbalance. This fertilizer addresses all three:

  • Nitrogen from feather meal and alfalfa meal corrects pale, yellow-green foliage
  • Iron and trace minerals from Azomite address interveinal chlorosis
  • Natural acidity helps maintain the 6.0–6.5 pH roses prefer

If yellowing persists, test your soil pH. Roses struggle in alkaline conditions above 7.0.

Is this safe for pets?

When used as directed and watered into the soil, this fertilizer poses minimal risk to pets. However, bone meal and fish bone meal can be attractive to dogs. We recommend:

  • Working the fertilizer into the soil rather than leaving it on the surface
  • Watering thoroughly after application
  • Keeping pets away from treated areas until fertilizer is absorbed
  • Storing bags in a secure location
How is this different from synthetic rose fertilizers?
Factor Organic (This Product) Synthetic Fertilizers
Release Speed Slow (4–6 weeks) Fast (immediate)
Burn Risk Very low High if over-applied
Soil Biology Feeds beneficial microbes Can harm soil life
Long-term Soil Health Builds organic matter No improvement
Application Frequency Every 4–6 weeks Every 1–2 weeks

For a more detailed comparison, read our article on Organic vs Synthetic Fertilizer: Key Differences and Tips on Choosing Your Type.

What's the best pH for roses?

Roses thrive in slightly acidic soil with a pH of 6.0–6.5. This is the range where nutrients are most available for uptake. Our organic formula naturally creates mild acidity as it breaks down, helping maintain optimal pH without additives.

If your soil is highly alkaline (above 7.0), consider adding sulfur or additional organic matter to lower the pH. Regular soil testing will help you track and adjust over time.

How does organic fertilizer improve my soil long-term?

Every application of this organic blend adds organic matter to your soil, which improves water retention, aeration, and nutrient-holding capacity over time. The meals feed beneficial soil microbes that create humus—the dark, crumbly material that makes garden soil rich and productive. For a detailed explanation of how soil microbes transform organic fertilizers into plant-available nutrients, see our article on How Do Soil Microbes Affect Plant Health?

How often should I apply this fertilizer?

Apply every 4–6 weeks during the active growing season. For most climates, that means 3–4 applications per year: early spring (when new growth appears), late spring (after first bloom), mid-summer (optional for repeat bloomers), and late summer (final feeding to build roots for winter). Stop feeding 6–8 weeks before your first expected frost to avoid encouraging tender new growth that could be damaged by cold.
