Alfalfa Meal (Triacontanol + Balanced NPK)

Our Australian-grown Alfalfa meal is the ideal choice for gardeners looking for a plant-based fertilizer that also revives soil & microbial activity!

Containing 3% nitrogen along with the ideal carbon to nitrogen ratio! This means it will break down quickly in the soil, but the nutrients will be released gradually, helping to minimize nutrient leaching. Because of this, it makes for an excellent fertilizer for fostering long-term healthy soil.

The Top Benefits of Alfalfa Meal

• Promotes Healthy Growth: Alfalfa meal is rich in nitrogen, which promotes healthy plant growth and development. It's a slow-release fertilizer that provides a steady supply of nutrients over time, leading to robust plants with strong stems and healthy foliage.

• Builds Soil Health: Alfalfa meal contains a range of trace minerals that help to build soil health and promote a healthy soil ecosystem. It's a natural soil conditioner that helps to improve soil structure and water-holding capacity.

• Increases Pest Resistance: The high level of saponins in alfalfa meal helps to repel pests, making it an effective and natural way to protect your plants.

• Encourages Earthworm Activity: Earthworms are attracted to the organic matter in alfalfa meal, which helps to improve soil aeration and water retention. This leads to healthier plants and better yields.

• Eco-Friendly and Sustainable: Alfalfa is a renewable resource that is grown without the use of synthetic fertilizers or pesticides. Using alfalfa meal in your garden is an environmentally conscious choice that promotes sustainable agriculture.

• Alfalfa meal will quickly increase the number of lateral branches on Roses & fruiting plants, resulting in bigger, healthier plants with more bud sights. Additionally, Dr Greenthumbs Alfalfa meal contains the powerful growth-regulating hormone triacontanol, which not only promotes plant cell division and promotes a larger root and branch system, but also contributes to fruit size and flavor with amazing results!

Alfalfa meal will also feed worms & other soil organisms and, in turn, your plants when added to your soil.

For those who love & practice organic gardening methodologies, it is the ideal choice for an all-natural fertilizer and is 100% unprocessed and plant derived! Its slow-release action gives plants a consistent stream of nutrients over a steady period, which will result in healthier foliage development and robust root systems. Alfalfa meal also contributes to the aeration and improvement of soil structure by activating soil microbes and earthworms, which results in better drainage and water retention.

Simply add 1/2 cup per plant (30L pot) or 1 cup per square meter to your soil. This fine-grade alfalfa meal will start to break down very fast! Reapply every 6-10 weeks.

FAQs:

What does Alfalfa Meal actually do for my plants?
It feeds gently (about 3% nitrogen) and steadily while waking up soil life—so you get stronger growth, better structure, and improved water-holding. It also naturally delivers triacontanol (a proven plant growth promoter) that helps push branching, roots, and flower/fruit set. 

Why is triacontanol a big deal?
It’s a natural 30-carbon alcohol first found in alfalfa that signals plants to photosynthesise harder and grow faster—without being a synthetic hormone. Expect denser branching, stronger stems, and more bud sites when it’s present. 

What’s the recommended dose?
For this product: mix in ½ cup per plant (≈30 L pot) or 1 cup per m², and re-apply every 6–10 weeks. It breaks down fast but releases nutrients slowly. 

Can I top-dress, or must Alfalfa Meal be mixed in?
Either works. Scratch it into the top few centimetres and water in, or blend it into potting mixes/bed prep. For a gentler start, top-dress and let the microbes do the rest. 

How about an alfalfa “tea”—is that worth it?
Yep. Lots of rose and veggie growers brew a quick tea to unlock soluble goodies (including triacontanol). A simple home recipe: ~1 cup meal per 20 L (5 gal), steep 2–4 days, stir daily, then drench soil. Don’t over-concentrate; it can get pongy and “hot.” 

Is Alfalfa Meal safe for seedlings and young plants?
Used lightly, it’s considered gentle. Go half-rate for tiny plants and avoid burying seeds in concentrated meal. If you want extra caution, brew a weak tea and water in. 

Will Alfalfa Meal burn my plants if I overdo it?
It’s hard to burn with alfalfa meal, but heavy hands can heat soil/compost and stress roots. Stick to the label rates above.

Is Alfalfa Meal good for compost too?
Absolutely—alfalfa is a classic compost activator. Add light layers to speed decomposition and maintain heat, especially in winter. Don’t dump in large clumps; sprinkle and mix. 

Does Alfalfa Meal help with pests?
Indirectly. Alfalfa contains saponins, which show antifeedant/insecticidal effects in studies. In real gardens it’s more of a “plant-health up, pressure down” effect—still use IPM for serious outbreaks. 

Will Alfalfa Meal change my soil pH?
Alfalfa meal trends mildly alkaline. In most beds it’s a non-issue at sane rates, but if you grow acid lovers (e.g., blueberries), monitor pH and adjust.

Which plants respond best?
Roses and flowering perennials love it; veggies and fruiting plants respond with fuller branching and better set. It’s broadly useful across beds, shrubs, and pots. 

Can I use Alfalfa Meal in pots/indoor grows?
Yes—great in soil and living mixes. For pots around 30 L, ½ cup mixed in or top-dressed is spot on. Water in well so microbes can get to work. 

Okay to combine with other amendments?
Totally. It plays nicely with kelp meal, worm castings, compost, and mineral blends. Many growers pair alfalfa + kelp for growth + resilience. 

Is Alfalfa Meal worm-bin friendly?
Yes—worms will process small amounts of alfalfa meal just fine; it can even nudge castings’ nutrient profile. Add modestly and mix with bedding to avoid heating. 

Does Alfalfa Meal attract rodents or wildlife?
Once worked into soil, usually no. But stored meal or surface piles can draw rodents—keep bags sealed and top-dress lightly, then cover. 

Is Alfalfa Meal pet-safe?
It’s plant-based and not considered highly toxic, but fertiliser isn’t pet food. Prevent grazing and store securely—some animals may react to alfalfa. If a pet ingests a lot, call your vet. 

How fast does Alfalfa Meal break down and how long does it feed?
It starts breaking down quickly (good carbon:nitrogen ratio) but releases nutrients gradually over weeks—hence the 6–10 week re-apply window.

Can I use Alfalfa Meal in hydroponic reservoirs?
No—this is a dry organic amendment for soil/living media. In hydro, it’ll cloud systems and feed biofilm. Keep it to soil, raised beds, and potting mixes. 

Is Alfalfa Meal Australian-grown?
This product is Australian-grown, plant-derived, and unprocessed. 

What’s in the bag, nutritionally?
A balanced plant-based mix with ~3% N, plus natural P, K and trace minerals (varies by crop). It’s formulated to boost growth and soil biology rather than hit plants with salts. 

How should I store Alfalfa Meal and how long will it keep?
Cool, dry, sealed container—think tight-lidded tub or metal bin to keep moisture and rodents out. Properly stored, it keeps for seasons without losing punch. 

Any red flags—plants I shouldn’t use Alfalfa Meal on?
Go easy around acid-lovers (azalea, blueberry) unless you’re managing pH; otherwise it’s widely safe. If in doubt, trial on a small area first. 

How do I layer Alfalfa Meal into a soil build (e.g., with TurboDirt or homemade mixes)?
Blend at ~½ cup per 30 L of finished media, or top-dress after transplant. Pair with quality compost/castings; then water in. Re-apply every 6–10 weeks. 

Will Alfalfa Meal help roses bloom harder?
Yes—rosarians swear by it for repeat bloom and bushy growth thanks to triacontanol. Use label rates or a light tea early in spring and mid-season. 

Can I over-heat my compost or bed with Alfalfa Meal?
If you dump a lot in one spot, yes—nitrogen fuels microbial heat. Sprinkle, mix, and keep moisture/airflow right to avoid hot pockets.
