The Pro Soil Enhancer bundle provides the essential combination to get your lawn and garden to the next level. With the inclusion of Quantum H, Activ8Mate, and Stimulizer, it won’t be long before your lawn and garden are thriving all year round. Using our earth-friendly products, you can also use the Pro Soil Enhancer bundle to grow healthy fruit and vegetables. The Plant Doctor range has been created using the science of nature, using the finest ingredients available. Each product has been individually selected to provide the required balance of nutrients to help your soil remain healthy and disease free throughout the hottest summer and coldest winter.
The bundle includes the following: -
Activ8Mate
Activ8mate helps stabilise nutrients in the rhizosphere, where they remain available over extended periods. Activ8mate is both a fertiliser and soil inoculant that can, in turn, feed the lawn, plants & trees.
Benefits: A N.P.K of 8-1-4 | Fish Liquid concentrate | Blood & Bone | Seaweed (Kelp) | Humic and Fulvic Acid | Trace elements and micronutrients.
Quantum H
Made famous by Ben Sims from Lawn Tips, Quantum-H helps improve, build & repair soil structure. It helps clean the soil from heavy metals, pesticides and herbicides etc and is an excellent microbe food.
Benefits: Premium humic acid solution / A high-grade Leonardite ore / Short-chain humic acid and fulvic acid molecules.
Stimulizer
Increase uptake of foliar-applied fertilisers, insecticides, herbicides & fungicides. Stimulizer-chelated materials rapidly enter the plant membranes (as little as 4hrs). Increases & stimulates beneficial soil microbial activity & reduces harmful microbes. It has a unique capacity to dissolve minerals & trace elements readily.
Benefits: This unique formula is a 'Trade Secret' invented by Plant Doctors' founder, Daniel Fitzhenry. Stimulizer has been used by Hydroponics Growers and other professional gardeners and farmers throughout Australia and around the world—one of the rare ingredients that can be mixed with Iron concentrate.

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!
