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. Not compatible with many products. Check the labels and do a jar test first.
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.

Product Application
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.
Popular Questions
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.

Magic Portion!
By: Shoua on 3 December 2023
A must have product in your gardening arsenal! I use this product every 3-4 weeks especially during the growing season to bring out the best in my lawn and neighbors wonder how my lawn stands out in the heat of summer when other lawns look somewhat colorless. The secret is in the ingredients and highly recommended everyone to include it in their shopping cart the next time you visit PD's website.
Awesome green up

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

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.

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.
