Why Choose the Garden Soil Enhancer Bundle:
(1318)
The science behind the Garden Soil Enhancer Bundle is built around improving nutrient transport, soil biology, and soil structure simultaneously, rather than relying on fertiliser alone.
Together, these inputs create a highly active soil ecosystem where nutrients are unlocked, stabilised, and efficiently absorbed, leading to stronger roots, improved plant resilience, and long-term soil fertility rather than short-term feeding.
The Plant Doctor range is formulated for maximum efficiency; most products require just 1 mL of concentrate per square metre (that’s 100 mL per 100 sqm). For example, 1L of Activ8Mate can treat up to 1,000 sqm of lawn or garden. Backed by a 90-day money-back guarantee, it’s easy to see why thousands of Aussie gardeners trust Plant Doctor.

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!
