Why FPE works

6 Reasons Your Garden Will Thank You

From the first application, you're investing in long-term garden health — not just quick-fix nutrition.

    Pre-digested minerals are instantly available to roots. Expect denser greens, stronger stems, and visibly healthier growth within weeks.

    Vegetative Growth

  • 🛡️ Stress Resilience

    Our probiotic inputs build a "microbial shield" around your roots — helping plants survive heatwaves, frost, and transplant shock.

    Plant Immunity

  • 🍓 Superior Blooms & Harvests

    Targeted ferments deliver the specific enzymes needed at each growth stage — larger flowers, more flavourful fruit, and higher yields.

    Fruiting & Flowering

  • 🦋 Safe for All Life

    Chemical-free, non-toxic, and completely safe for children, pets, bees, butterflies, and every living thing that calls your garden home.

"Because these are true living ferments, they carry a distinct earthy, pickled aroma. This is the scent of active lactic acid bacteria — the same beneficial microbes found in yogurt and kombucha. It's not a flaw; it's proof of life.

Once diluted and watered in, it disappears — leaving only the biological benefit behind."

How to use

Simple to Use, Impossible to Overdo

FPEs are designed for beginners and experienced growers alike. Always dilute before use. You literally cannot use too little.

1

Choose Your Tonic

Select based on your goal — see the guide above, or start with our Probiotic Soil Tonic for everything.

2

Dilute in Water

Always dilute your FPE before applying. Never apply undiluted concentrate directly to plants or soil.

3

Apply to Soil or Leaves

Water into the root zone, or use a sprayer for foliar applications. Early morning or late afternoon is ideal.

4

Apply Regularly

Every 2–4 weeks during active growth. Consistency matters more than strength — gentle & regular wins.

Collapsible content

What exactly is a Fermented Plant Extract?

An FPE is a liquid concentrate made by fermenting fresh plant material — comfrey, seaweed, pumpkin, herbs — with a sugar source and beneficial microbes like Lactic Acid Bacteria (LAB) or EM-1. The fermentation process breaks down plant matter, making nutrients, enzymes, and growth compounds bioavailable to your garden plants and soil biology.

Are FPEs the same as liquid fertilisers?

No — they work very differently. Standard liquid fertilisers deliver soluble nutrients directly to plants. FPEs feed and stimulate your soil's microbial ecosystem, which in turn unlocks nutrients naturally. FPEs also deliver plant growth hormones, enzymes, and beneficial microbes that fertilisers simply don't contain.

Why do they smell? Is that normal?

Mushroom mycelium is a living organism. Extended time in transit — especially in warm Australian conditions — can stress or damage the colonised block. Express post minimises exposure to heat and dramatically improves the condition of blocks on arrival. Add the Express Post Addon product with a matching quantity when ordering.

Can I use these on vegetables and food gardens?

Absolutely. Our FPEs are 100% organic, chemical-free, and non-toxic. They are widely used in organic vegetable gardens, permaculture systems, and natural farming. Apply to soil or as a foliar spray — just maintain the recommended dilution ratios and avoid applying to produce right before harvest.

How soon will I see results?

FPEs work cumulatively, not instantly. Many growers notice improved leaf colour and recovery from stress within 2–4 weeks of regular use. The biggest benefits — improved soil structure, increased resilience, and richer harvests — build over a full season. Unlike synthetic fertilisers, you're building biological wealth, not borrowing against it.

How do I know which product to start with?

For absolute beginners, our Probiotic Soil Tonic Concentrate or Comfrey Fermented Extract is the ideal starting point — it works on everything. If you want to target a specific outcome, use our product guide above: Seaweed for stressed plants, Pumpkin for fruiting and growth, and Frass for pest resistance.

Can I combine different FPEs together?

Yes! FPEs combine beautifully with each other and with other microbial inputs like EM-1 Bokashi liquid or compost teas. Many experienced growers rotate between products — for example, Seaweed one week and Comfrey the next. Just avoid mixing with synthetic chemicals or chlorinated tap water (let it sit 24 hours first).

How long does a bottle last?

Because these are concentrated — diluted at 1:500 to 1:1000 — a single litre goes an incredibly long way. One litre makes up to 1,000 litres of ready-to-use tonic. For a typical home garden applying fortnightly, one bottle can last an entire growing season. Store in a cool, dark place and use within 12 months of opening.

Are these safe around pets and children?

Yes. Our FPEs are 100% non-toxic and chemical-free. They are safe for pets, children, bees, butterflies, earthworms, and all beneficial garden life. We use the same products on our own farm at Tamborine Mountain where our family and animals live and work daily.

What is EM-1 and why do you use it?

EM-1 (Effective Microorganisms) is a consortium of beneficial microbes — Lactic Acid Bacteria, yeasts, and phototrophic bacteria — developed by Japanese microbiologist Dr Teruo Higa. We use it as both a fermentation catalyst and a soil probiotic. It drives the fermentation of our plant extracts AND inoculates your soil with biology that improves structure, nutrient cycling, and long-term fertility.
