Organic Plant Food 100ml

$17.00

An organic fertiliser that feeds your plants — and their soil.

With a 13-3-8 NPK and a unique mix of microbes, kelp, humic acids, and wood vinegar, our Organic Plant Food improves soil health, boosts nutrient cycling, and promotes vigorous, balanced growth. Beneficial microbes help outcompete pathogens and convert nutrients into plant-available forms, while biostimulants support strong root systems and sustained foliage development. Safe for all soil types and made to reduce nutrient runoff for genuinely sustainable growth.

Soil Health Champion: Strengthens soil biology and structure for sustained fertility.

Eco-Positive: Reduces reliance on mined fertilisers and minimises nutrient runoff.

Neutral pH, Low Salt: Gentle on roots, safe for indoor and outdoor use.

Australian-Ready: Designed for performance across diverse soil types and climates.


Why It Works

Nitrogen (13%) – Fuels leafy expansion and rich green growth while stimulating beneficial microbial activity.

Phosphorus (3%) – Encourages deep, resilient root systems and supports flowering and fruiting.

Potassium (8%) – Improves leaf strength, enhances colour, and builds resilience against stress.

Sulphur (1%) – Vital for protein synthesis and nutrient absorption.

Magnesium (0.1%) – Central to chlorophyll production and photosynthesis.

Iron (trace) – Keeps new growth vibrant and prevents chlorosis.

Beneficial Microbes – Inoculate soil with trillions of living organisms that outcompete pathogens and cycle nutrients naturally.

Kelp, Humic Acids & Wood Vinegar – Work together to boost seed germination, enhance root growth, and improve soil structure for better aeration and water retention.


Best For:

  • All indoor and outdoor plants
  • Garden beds, containers, and edibles
  • Gardeners wanting a sustainable, microbe-rich fertiliser for lasting results

Add 1ml Organic Plant Food to 1L of water. 

Spring–Summer (active growth): Apply every 2–3 weeks at half to full strength.
Autumn: Reduce to every 4 weeks at half strength.
Winter (resting): Use sparingly, every 6–8 weeks at quarter strength.

Shake well before use. Apply directly to soil or as a foliar spray.

FAQ

What’s it best for?

Wetting moss poles and pole fill like our Tree Fern Fibre, keeping cuttings and seedlings damp while they root, and giving plants a light foliar feed.

Will misting raise the humidity around my plant?

Only for a few minutes. A fine mist evaporates quickly, so it won’t change the air around a plant in any lasting way. Where misting really earns its place is keeping moss poles, cuttings and seedlings damp.

Can I foliar feed with it?

Yes. Indoor Plant Food can go on as a light foliar feed, mixed as per the directions. Keep it off plants in direct sun and away from hairy, delicate or freshly unfurled leaves. Mixed plant food keeps for 48 hours, so tip out anything left after that.

How much does it hold?

300ml.

Is any of it plastic?

No. It’s handmade from solid brass with a hammered finish, so no two are exactly the same.

Will the brass change colour?

Yes. Solid brass darkens and develops a patina with age and handling. That’s part of its character.
