The Plant Doctor range has been created using the science of nature, using the finest ingredients available. MaxGreen provides a highly available form of liquid Iron (Fe) and Nitrogen (N) to produce a rich green colour in leaves & help correct iron deficiencies in your lawn.
The addition of Fulvic acid will supercharge the nutrient uptake providing fast results. It will also help to prolong the life of the nutrients, holding them for longer where they are
Iron (Fe) is a vital micro-nutrient plants require to form chlorophyll. And chlorophyll is what gives plants/lawns their green colour. Iron deficiency occurs when there is either insufficient iron in the soil or the iron is tied up and unavailable due to high pH (alkaline soil) or poor aeration. It can also be induced by an overabundance of calcium in the soil or an over-application of lime.
Iron chlorosis is the name of the condition found in plants that are iron deficient. It is one of the most common micro-nutrient problems of ornamentals, shrubs, vines, small fruits, and trees. The leaves of affected plants are yellow, light green, or white with distinct green veins.
TYPICAL ANALYSIS (w/v)
Nitrogen (N) 16%
Iron (Fe) 5%
Sulphur (S) 2%
Provide a light water in after application.
WARNING - Avoid applying in hot weather. Product will stain (concrete/clothes/skin). Apply with care and wash hands after use. Keep away from water sources (ponds, pools, etc.) Iron deficiency can indicate a high pH or alkaline level in soil. If yellowing persists or returns rapidly after treatment, check soil pH and adjust if necessary. Intended to provide immediate relief for plants and soil, however, is an inadequate long-term solution for iron deficiency.
DO NOT SWALLOW. Product may act as an irritant. Avoid inhalation and contact with the eyes & skin. Keep out of reach of children. Store sealed in a cool place.
Iron products can have an adverse reaction with our darker liquids. To avoid blockages in sprayer nozzles we recommend applying the Iron separately to other products. (Stimulizer is safe to mix with Iron). If attempting to mix together, try a jar test in the ratios you want to apply them in first. Iron should always be added last after all other products are diluted with water.
Applied separately at various frequencies allows you to tailor nutrient input based on the soil/plant/lawns requirements and condition.
Question: Should I water the lawn after applying Max Green or wait 24 hours?
Answer: Foliar uptake can only happen while the leaf is wet. Max Green works best when lightly watered in after application to get into the soil. Environmental factors (time of day it’s applied, wind, precipitation, time left on the leaf, soil pH, etc) can also play a part in how well it works when applied and as these often change, you may experience different results with each application.
Question: Can I mix Max Green with other products?
Answer: Max Green should not be mixed with other products, except for Stimulizer.

Awesome green up
By: Joel on 19 September 2023
I just applied this to my recently scalped lawn. Within 2 days the exposed undergrowth has greened up and thanks to the added nitrogen, is pushing some good growth! Again, unbeatable value and a highly effective product. Definitely recommend.
Get it Green

I've been using Liquid Iron for ages to help green up my lawn, but MAXGreen gives your lawn that added green kick of Nitrogen. Get it!
Best all round spray
By: Sonny on 28 April 2023
I think this product is the best all rounder to keep that green grass, and make sure its healthy. I have buffalo and its spectacular. It wont fix soil issues or nutrient issues. But once those are under control, this is the perfect thing to spray over once a month for that deep lush green that the neighbours are jealous of
By: Blake on 4 April 2023
Great product, used in conjunction with some other products and has worked great on the lawn!
Gives lawn to envy

Changed to plant doctor from another brand and have been very happy. Max green gets your lawn a lush dark green colour that people have to feel to see that it truly is real lawn.
By: Leigh on 22 January 2023
Normally the Doctors I see deliver me grief...but the Plant Doctor continues to deliver me good news over and over again. This Max Green does exactly as it says...and I dare say that as far as a deep green turf colour...my lawns would give the Adelaide Oval a run for their money. Thanks again Plant Doctor.

My neighbours are green with envy … amazing results in days!
By: Daryl on 24 September 2021
I have been using MaxGreen for a couple of months now and have really noticed how much greener the lawn becomes after application. Even through the colder months it works wonders. Looking forward to when the sun comes out and the grass begins to grow. Along with using the other plant doctor products, the results will be stunning.

Perfect tool to survive the cold frosts of Victoria. No frost burn or colour loss through winter.
By: Brian on 1 March 2021
After much deliberation I chose the Champion Maxgreen over the standard iron fertilizer and am really pleased with overnight results. Applied immediately after mowing in the afternoon and woke up the next morning to a deep green SWB lawn. Plant doctor products have many good reviews and pleased to say that I am very impressed and will stay with Plant doctor. Thank you
Green for Dayz
By: Anthony on 21 January 2021
I have waited so long to get a good enough lawn that could benefit from liquid iron. The directions were simple and the results of a deep dark green in my lawn was within a day of application. Amazing results and will be a return customer of this product.

The Only Nitrogen & Iron Fertiliser You Need
By: Kristian on 25 April 2020
I sprayed only along the edge to see how well this product would work. I came home from work the next day and noticed a dark green strip along the edge of my lawn, it took me a moment to realise what was going on, then i realised. I was over the moon to see how quick and amazing the results were. So i highly recommend this product if you are wanting a quick boost in colour and growth!
