Organic Rose & Flower Fertilizer 4-7-5

A premium, slow-release blend of organic meals and volcanic minerals designed to produce vibrant blooms, deep colors, and healthy soil biology. Perfect for roses, flowering perennials, and bloom-heavy vegetables.

WHY GROWERS CHOOSE THIS FORMULA

🌹 Bloom-Focused NPK

Higher phosphorus (7%) specifically targets bud formation and flower size, while preventing leggy growth from excess nitrogen.

🦠 Feeds Soil Biology

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

🐾 Slow-Release & Gentle

Won't burn roots or shock transplants. Nutrients release gradually over 4-6 weeks as soil microbes break down organic matter.

🌋 70+ Trace Minerals

Azomite volcanic ash provides micronutrients most soils lack—enhancing flower color, fragrance, and disease resistance.

✅ CDFA Registered ✅ OMRI-Listed Ingredients ✅ Made in USA

Phosphorus 7%
The Bloom Nutrient
🌸 WHY HIGH PHOSPHORUS?
Phosphorus is THE bloom nutrient. It triggers flower bud formation, develops strong root systems, and intensifies petal colors.
  • More blooms: Triggers bud initiation
  • Deeper roots: From fish bone & bone meal
  • Vibrant color: Intensifies pigmentation

APPLICATION RATES & DIRECTIONS
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 = approximately 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.

FREQUENTLY ASKED QUESTIONS
Q 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.

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

Q 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.

Q 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
Q 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
Frequency Every 4-6 weeks Every 1-2 weeks
Q 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.

5.0 5.5 6.0-6.5 ✓ 7.0 7.5
← Too Acidic | OPTIMAL FOR ROSES | Too Alkaline →

Our organic formula naturally creates mild acidity as it breaks down, helping maintain optimal pH without additives.
