Founded with a passion for improving the way plants grow, Plant Doctor develops and supplies premium fertilisers, soil conditioners and plant health products designed specifically for Australian growing conditions. From home gardeners and lawn enthusiasts to commercial growers, turf managers and horticultural professionals, our goal is simple: to help people grow healthier plants through effective, environmentally conscious solutions. For over 30 years, Plant Doctor has combined traditional agricultural knowledge with modern plant science to create products that support stronger soils, healthier roots and more resilient plants.
Plant Doctor’s foundations began in the agricultural and horticultural industries, where founder Daniel Fitzhenry spent more than three decades developing his knowledge of soil health, plant nutrition and sustainable growing practices. Through years of working with some of Australia’s largest agricultural and horticultural companies, Daniel gained valuable experience sourcing high-quality ingredients from Australia and around the world. His vision was to combine proven agricultural practices with natural ingredients such as seaweed extracts, humic acids, fulvic acids, minerals and botanical extracts to create premium plant health solutions. Many of these formulations have become trusted by growers, landscapers and gardening enthusiasts across Australia.
Following Daniel’s passing in 2018, his eldest son Adam continued his father’s vision and expanded Plant Doctor into a trusted retail brand for Australian gardeners, lawn enthusiasts and plant lovers. With a background in business development and entrepreneurship, Adam introduced a broader range of products designed to make professional-quality plant health solutions accessible to everyday gardeners. Today, Plant Doctor remains proudly family-owned and operated, with multiple generations of the Fitzhenry family involved in continuing the company’s mission.
Plant Doctor specialises in developing effective, economical and environmentally conscious products using quality ingredients.
These ingredients include: Seaweed extracts, Humic and fulvic acids, Natural minerals, Silicates, Botanical extracts and Soil conditioning compounds. Our products are designed to support:

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
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!
