Ideal Applications
FEATURES
🌱 Natural Triacontanol Growth Stimulant
Contains triacontanol, a naturally occurring fatty alcohol studied for its ability to enhance photosynthesis, stimulate root development, and promote new growth — many gardeners notice a response within the first week of application.
🌹 Rose Grower's Go-To Organic Fertilizer
The preferred organic amendment of professional rose exhibitors for decades. Promotes basal breaks (new canes from the base) and abundant, larger blooms without any risk of burning.
⚡ Fast Response Plus Sustained Feeding
Dual-action organic nutrition: triacontanol supports a rapid growth response, while the meal releases nitrogen and potassium gradually over 4–8 weeks as soil microbes break it down.
🦠 Builds Soil Microbial Activity
Feeds beneficial bacteria and fungi in the soil food web. Regular applications increase biological activity, improve nutrient cycling, and build healthier, more resilient soil over time.
🧪 Balanced Nitrogen & Potassium Source
Equal parts nitrogen and potassium (2.5-0-2.5) support both vegetative growth and plant vigor in a single application. Pair with a phosphorus source like bone meal for a complete organic feeding program.
🔥 Zero Burn Risk for All Plants
Gentle, slow-release organic nutrition that will not burn roots, foliage, or seedlings even when over-applied. Safe for vegetables, flowers, trees, shrubs, and houseplants.
♻️ Powerful Compost Activator
High nitrogen content and microbial stimulation accelerate compost decomposition. Add 2–3 cups per pile to jumpstart breakdown and increase compost quality.
🫖 Versatile Application Methods
Apply as a dry soil amendment, top dressing, or brew into alfalfa tea for faster nutrient delivery. Finely ground meal dissolves easily for foliar sprays and root drenches.
🏗️ Improves Soil Structure
Adds organic matter that enhances water retention in sandy soils and improves drainage in clay soils. Builds better tilth and root penetration with every application.
🔬 Tested for Heavy Metals
Independently lab tested for heavy metal content. CDFA registered, 100% organic, sourced from non-GMO alfalfa, and manufactured in the USA to strict quality standards.
DERIVED FROM
Our Organic Alfalfa Meal is derived from a single, premium-quality source — non-GMO alfalfa grown and processed in the United States. Unlike synthetic fertilizers that blend multiple chemical salts, this product is the whole dried alfalfa plant, finely ground to maximize nutrient availability and soil contact.
Primary Ingredient
Naturally Present Nutrients
Trace Minerals
Alfalfa's deep taproot system mines calcium, magnesium, iron, and other trace minerals from deep soil layers, concentrating them in the plant tissue.
Triacontanol
A naturally occurring 30-carbon fatty alcohol found in alfalfa wax that stimulates photosynthesis, root growth, and cell division in treated plants.
SCIENCE BEHIND THE FORMULA
2.5-0-2.5: Balanced Growth Without Excess Phosphorus
This formula provides nitrogen for vegetative growth and potassium for plant vigor and disease resistance. Alfalfa naturally contains no significant phosphorus, so pair with a bone meal product for complete NPK coverage. The real magic is triacontanol, a natural growth stimulant unique to alfalfa that synthetic fertilizers cannot replicate. Best performance when soil temperatures are above 55°F and kept evenly moist.
🌿 Nitrogen — 2.5% (Vegetative Growth)
Moderate, slow-release nitrogen from organic plant protein. Feeds gradually over 4–8 weeks as soil microbes mineralize the meal — promoting steady, healthy foliage growth without the flush-and-crash cycle of synthetic nitrogen.
🌸 Phosphorus — 0%
Alfalfa naturally contains no significant phosphorus. If your soil test shows a phosphorus need, pair with Bone Meal 3-15-0 or Fish Bone Meal 4-17-0 for complete nutrition.
⭐ Potassium — 2.5% (Vigor & Resilience)
Balanced potassium supports disease resistance, drought tolerance, bloom quality, and overall plant vigor. Especially important for roses, flowering perennials, and fruiting vegetables that demand strong K levels throughout the growing season.
Why Alfalfa Meal Outperforms Other Organic Amendments
🧬 Triacontanol Growth Stimulation
Triacontanol is a natural plant growth regulator found in alfalfa wax, studied for its effects on photosynthetic rate, cell division, and root elongation — benefits no other common organic meal provides.
🌹 Promotes Basal Breaks in Roses
The combination of triacontanol and balanced N-K nutrition stimulates new basal canes (breaks from the base of rose bushes), leading to more vigorous, productive plants with increased bloom capacity.
🦠 Microbial Soil Ecosystem Builder
Unlike synthetic fertilizers that bypass the soil food web, alfalfa meal feeds beneficial bacteria and fungi directly. This builds long-term soil health, improves nutrient cycling, and creates a self-sustaining growing environment.
🛡️ Gentle Organic Nutrition — Zero Burn Risk
Organic amendments like alfalfa meal release nutrients slowly through microbial decomposition, so there's no risk of chemical burn to roots, foliage, or seedlings — even when generously applied. Safe to use liberally throughout the growing season.
What to Expect After Application
Results vary with soil temperature, moisture, and microbial activity. Best performance when soil temps are above 55°F.
APPLICATION RATES & DIRECTIONS
Apply alfalfa meal at planting time and throughout the growing season. Work into soil or use as top dressing. Water in well after application to activate microbial breakdown. Can be reapplied every 4–6 weeks without risk of burning.

HOW TO USE
Soil & Garden Beds
- Measure the appropriate amount based on your garden size and crop type (see Application Rates above).
- Spread alfalfa meal evenly over the soil surface.
- Work into the top 2–4 inches of soil with a garden fork or rake.
- Water thoroughly to begin microbial breakdown and nutrient release.
- Reapply every 4–6 weeks throughout the growing season.
Container & Potted Plants
- Measure 1–2 teaspoons per gallon of pot size.
- Sprinkle evenly over the soil surface or mix into the top inch of potting mix.
- Water normally — nutrients will release gradually as the meal decomposes.
- Reapply every 4–6 weeks during the growing season.
Alfalfa Tea (Liquid Application)
- Add 1 cup of alfalfa meal to 5 gallons of water in a bucket or container.
- Stir well and let steep for 24–48 hours, stirring occasionally.
- Strain the liquid through cheesecloth or a fine mesh screen.
- Apply directly to the soil as a root drench or use as a foliar spray.
- Use within a few days for best results — the tea will begin to ferment.
Compost Activation
- Add 2–3 cups of alfalfa meal per compost pile or bin layer.
- Mix into green/brown materials as you build the pile.
- The high nitrogen content and microbial stimulants accelerate decomposition.
- Turn the pile as usual — you'll notice faster breakdown and higher temperatures.
Pro Tip: Champion Rose Feeding
For the best rose results, apply 1 cup of alfalfa meal around the drip line of each bush in early spring to trigger basal breaks — those thick new canes that produce the biggest flowers. Follow up monthly through the growing season, and pair with Epsom Salt for deeper green foliage.
When Alfalfa Meal Is the Right Choice
- You want gentle, sustained organic feeding that builds soil life over time
- You're growing roses, flowers, vegetables, or activating compost
- You want a non-burning amendment safe for all plants, including seedlings
- Your soil is warm (above 55°F) with active microbial life
When to Consider Other Options
- You need fast, measurable nitrogen immediately — cold soil or sterile potting media slows microbial breakdown. Consider pairing with a water-soluble fertilizer for an initial boost
- You're correcting a severe nutrient deficiency — alfalfa meal is a gentle feeder, not a rescue product. Pair with a targeted amendment for faster correction
- You need phosphorus — alfalfa meal has 0% P. Add Bone Meal or Fish Bone Meal for root and bloom support

FREQUENTLY ASKED QUESTIONS
What makes alfalfa meal special for roses?
Alfalfa meal contains triacontanol, a natural growth stimulant that promotes basal breaks (new canes from the base) and prolific blooming. Rose growers have relied on alfalfa meal for decades as their go-to organic fertilizer. The balanced 2.5-0-2.5 formula provides nitrogen for foliage and potassium for bloom development.
How fast does alfalfa meal work?
Many gardeners notice a growth response within the first week or two thanks to triacontanol. Full nutrient release occurs gradually over 4–8 weeks as soil microbes break down the organic matter. Results vary with soil temperature, moisture, and microbial activity.
Is this alfalfa meal pellets or powder?
Our Alfalfa Meal is a finely ground meal (powder texture), not pellets. This form breaks down faster in soil, mixes easily into potting media, and is ideal for making alfalfa tea or activating compost piles. Pellets take significantly longer to decompose.
How does alfalfa meal compare to synthetic fertilizers?
Unlike synthetic fertilizers that deliver a quick nutrient spike and can burn plants, organic alfalfa meal feeds gently over 4–8 weeks and is completely non-burning. More importantly, it builds long-term soil health by adding organic matter and feeding beneficial microbes — something synthetic fertilizers cannot do. For a deeper comparison, read Organic vs Synthetic Fertilizer: Key Differences and Tips.
Does alfalfa meal attract pests or animals?
Alfalfa meal has a mild, earthy scent that does not generally attract pets or garden pests. It's much less appealing to animals than bone meal or blood meal. For best results, work it into the top few inches of soil after application rather than leaving it on the surface.
Can I make alfalfa tea fertilizer?
Yes — alfalfa tea is an excellent way to deliver nutrients and triacontanol directly to roots and foliage. Add 1 cup of alfalfa meal to 5 gallons of water, steep for 24–48 hours stirring occasionally, strain, and apply to soil or use as a foliar spray. Use within a few days for best results.
Is alfalfa meal safe for all plants?
Yes. Alfalfa meal is a gentle, non-burning organic plant food safe for vegetables, flowers, trees, shrubs, and houseplants. It's particularly popular for roses, tomatoes, peppers, and flowering perennials. Safe to use around children and pets when applied as directed.
How does alfalfa meal improve soil health?
Alfalfa meal adds organic matter that improves soil structure and water retention, stimulates beneficial microbial activity, and enhances nutrient cycling. Regular use builds healthier, more productive soil over time — feeding both your plants and the ecosystem that supports them.
Can I use alfalfa meal with other fertilizers?
Absolutely. Alfalfa meal combines well with other organic amendments. Popular pairings include Bone Meal (adds phosphorus), Kelp Meal (adds trace minerals), and Epsom Salt (adds magnesium). See the Complete Your System section for specific recommendations.
Will alfalfa meal change my soil pH?
Alfalfa meal has a minimal effect on soil pH. As it decomposes, it may contribute a very slight acidifying tendency, but the impact is negligible in most garden soils. It's safe to use without worrying about pH swings.
Does alfalfa meal smell?
Alfalfa meal has a mild, earthy, hay-like scent — much less odor than blood meal, fish-based products, or manure. Most gardeners find the smell pleasant and barely noticeable once worked into the soil.
Can alfalfa meal mold on the soil surface?
In warm, humid conditions you may notice a white or gray surface mold on alfalfa meal left on top of soil. This is harmless — it's actually a sign of beneficial microbial activity. To prevent it, work the meal into the top few inches of soil and water in after application.
Is alfalfa meal safe around pets?
Alfalfa meal is generally safe around pets when applied as directed. It's a natural plant material with low toxicity. However, discourage pets from eating it directly in large amounts, as it could cause mild digestive upset. Working it into the soil after application keeps it out of reach.
