Ideal Applications
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.

Micronutrient & Mineral Sources
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 |
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 |
HOW TO USE
Garden Beds & In-Ground Planting
- Measure the appropriate amount based on area (¼ cup per sq ft for beds, ½–1 cup per rose bush).
- For new plantings, mix fertilizer into the backfill soil before placing the plant in the hole.
- For established plants, scratch fertilizer into the top 2–3 inches of soil around the drip line using a hand cultivator.
- Water deeply after application to activate microbial breakdown and prevent surface crusting.
- Reapply every 4–6 weeks during the growing season, following the seasonal schedule above.
Container & Potted Plants
- Mix ¼ cup of fertilizer per gallon of potting soil before planting.
- For existing container plants, sprinkle 2–3 tablespoons on the soil surface.
- Gently work into the top inch of soil with a fork, being careful not to disturb roots.
- Water thoroughly until water drains from the bottom of the container.
- Reapply every 4–6 weeks. Container plants may benefit from slightly more frequent feeding since nutrients leach with watering.
Top Dressing & Side Dressing
- Apply 2–3 tablespoons around the base of each plant, keeping fertilizer 2–3 inches away from stems.
- Cover the fertilizer with a thin layer of mulch (1–2 inches) to retain moisture and accelerate breakdown.
- Water gently to settle the fertilizer into the mulch layer.
- This method works well for mid-season feeding of established perennials and shrubs.

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 |

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.
