Ultra-Concentrated Fulvic Acid Bio-Stimulant & Natural Chelator

Unlock healthier soil, stronger roots, and bigger plant yields—naturally.

Super concentrate Bio-stimulant & natural chelating agent - with natural stimulants, minerals, and nutrients. Super concentrate, premium Fulvic acid-based product. A powerful bio-stimulant containing more than 75 minerals, humic acid extracts, and natural plant stimulants.

This unique formula, a ‘Trade Secret,’ was invented by Plant Doctor’s founder, Daniel Fitzhenry, with remarkable results. Stimulizer is widely used by hydroponics growers and professional growers across Australia and worldwide. It provides an immediately available form of food for plants and soil microbes, essential for healthy soil. Stimulizer effectively eliminates root rot diseases under certain conditions and stimulates root growth in a way that no other known product can. Compatible with both acidic and alkaline materials, Stimulizer is one of the most valuable inputs for creating a healthy, well-balanced soil environment for plants to thrive. Often referred to as the ‘missing link’ in plant nutrition.

Why Use Stimulizer?

  • Fights root rot & disease naturally
  • Accelerates root growth & nutrient absorption
  • Unlocks “locked-up” nutrients in soil
  • Boosts beneficial soil microbes & suppresses harmful ones
  • Improves water retention & reduces wilting
  • Enhances brix, yield, and resilience
  • Compatible with fertilisers, sprays, and all pH levels

 

           For Lawns & Turf (Buffalo, Couch, Kikuyu & More)           
  •       Apply via hose-on sprayer or watering can
  • Strengthens root zone and boosts drought tolerance
  • Ideal after topdressing, scarifying or stress recovery
  • Enhances colour and growth without excessive leaf stretch

Tip: Use with lawn fertiliser to increase uptake and reduce leaching.      

           For Home Gardens (Veggies, Flowers, Citrus & Herbs)           
  •       Mix into watering can or apply as a foliar spray
  • Improves flowering, fruiting, and overall vigour
  • Reduces plant stress and improves flavour (brix) in produce
  • Helps roots reach more water and nutrients, especially in poor soil

Ideal For: Pots, raised beds, garden beds, indoor plants      

           For Hydroponics & Controlled Environments           
  •       Supports sterile system health by reducing root rot
  • Stimulates nutrient uptake via foliar feeding or irrigation
  • Safe for pH fluctuations and mixes well with most additives
  • Boosts resilience during high-stress periods (low light, transplanting, temperature fluctuations)      

 

Used by hydroponic experts, landscapers, and commercial growers across Australia, Stimulizer is the secret weapon behind fast-rooting cuttings, rapid recovery after stress, and yield bumps that speak for themselves. It blends effortlessly into any garden or crop program and makes everything you apply—fertilisers, sprays, tonics—work harder and smarter. Once you try it, you’ll wonder how you ever grew without it.

The Science Behind Stimulizer

Stimulizer works through a unique combination of chelation, microbial stimulation, and cell signalling that improves plant and soil function from day one. Stimulizer functions as a highly bioavailable fulvic acid complex with a cation exchange capacity (CEC) of 1500—making it one of the most effective natural chelators available. Its low molecular weight allows rapid translocation of micronutrients through plant cell membranes, often within 4–6 hours of application. By stimulating root exudation and microbial colonisation in the rhizosphere, Stimulizer enhances enzymatic activity, nutrient cycling, and overall soil biofunction. The formulation also supports stomatal conductance and chloroplast activity, boosting photosynthetic efficiency even under abiotic stress such as cloud cover, salinity, or heat.

Function Description
Natural Chelator Fulvic acid binds to locked-up minerals, making them instantly plant-available (even within 4 hours)
Root & Shoot Growth Stimulates root hair development and cell elongation, giving plants deeper access to nutrients
Photosynthesis Booster Opens stomata to improve energy conversion, especially in cloudy or humid conditions
Disease Suppression Reduces harmful microbes (e.g. Pythium) and boosts beneficial microbial populations
Plant Immune Activation Increases resistance to pests, wilting, and environmental stress
Yield Enhancer Improves flowering, brix levels, and fruit set through increased nutrient absorption
Soil Detoxifier Helps break down chemical residues (herbicides, pesticides, heavy metals) and stabilises nitrogen (urea)f

Tired of plants stalling in poor soil or not responding to fertiliser? Stimulizer flips the switch. It activates your soil’s natural potential, unlocking tied-up nutrients and feeding beneficial microbes—all within hours. Whether your plants are stressed, sluggish, or just need a kickstart, Stimulizer brings them back with a visible surge of energy and vitality.

Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
