Iron (Fe) is a vital micro-nutrient required by plants in order to form chlorophyll. And chlorophyll is what gives plants/lawn their green colour. Iron deficiency (chlorosis) occurs when there is either not enough 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 over-abundance 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. Appearing first on the young/new leaves, Leaves of affected plants are yellow, light green, or white with distinct green veins.

TYPICAL ANALYSIS W/V
Iron (Fe) = 7%
Sulphur (S)= 3%
Do not spray in hot weather conditions
Iron can stain paths, concrete, paving, clothes and skin, so always wear old clothes, wash hands after use and be careful when applying near concrete and paths etc. Wash off immediately any lasting damage. Keep away from water sources such as ponds, pools etc.
Iron deficiency in many plants & lawns is an indication of high pH or alkaline soil. If yellowing persists or returns rapidly after treatment, soil pH should be checked and adjusted if necessary.
Follow application directions as excess liquid iron can lead to other problems, such as zinc and manganese deficiencies. While liquid iron provides immediate relief for plants & soil, it is not an adequate long-term solution for an iron deficiency. Keeping plants/Lawn in well-drained soil amended with sulphur to reduce the pH level can help iron in the soil become more available to plants.
Question: Should I water the lawn after applying Liquid Iron or wait 24 hours?
Answer: Liquid Iron doesn’t have to be watered in however, some do prefer to water it in, so either option is alright. 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 Liquid Iron with other products?
Answer: Liquid Iron should not be mixed with other products, except for Stimulizer.

I bought a bulk order of the ben sims pack which included this product and a variety of others. I Have been very satisfied this season with the results. Grass has handled the temperatures well with the assistance to plant doctors foliar products. The turf looks great and loves the applications. At a competitive price, i highly recommend.
the Iron gives it that extra green-up boost and makes the lawn really pop!
Instant green up
By: Josh on 7 July 2021
I use this product on my lawn for a green up every one to two months. I applied it twice in one month but it was too much and my lawn had an ugly grey colour.
Top shelf iron
By: Steve on 2 July 2021
One of the best iron products I’ve used on the market.
Deep Green liquid iron
By: Christopher on 16 June 2021
I love this product. Produces a very appealing deep green colour in your lawn and when supplemented by the activ8Extra liquid fertilizer you will get amazing results. I will keep purchasing and using these products. 10/10 would recommend.
A must have for a lush lawn!
By: Shoua on 4 June 2021
I have used various brands of Iron, but nothing comes closer to PD's Iron Fertilizer where results are concerned. Iron is an essential plant food and I usually apply the recommended dose late afternoon to enjoy the results overnight - its so satisfying to see the difference!
By: Blake on 26 March 2021
Great to add while spraying PGR
By: Dylan on 22 March 2021
Every time I apply as a foliar application, I see results within 10-15 mins - especially when applying with a bit of Stimulizer. It's very effective and greens up well over the coarse of a day or two. I love this product the most of all Plant Doctors products. I'm now buying it in 20L
By: David on 20 February 2021
First time using liquid iron on my lawn and I was amazed how well it works and how much greener it is.

My favourite product!
By: Sheldon on 9 January 2021
I love using Plant Doctor's liquid iron. It always makes my lawn 'pop'. It is fast acting too.
By: Tyler on 4 January 2021
I purchased the Ben Sims Lawn Tips pack for my instant turf couch and all of the products have been sensational. The improvement in my couch at a former residence, in which I did not use these products, and the couch at our new place, in which I use these products, is 10 fold. Very happy.
Liquid iron results!
By: Nicholas on 29 December 2020
I bought this as part of the Ben Sims pack and I am seeing good long term results where my buffalo lawn is staying greener for longer. Love it. I'll be continuing to buy this, but in a bigger size!
Go green or go home!
By: Nathan on 9 December 2020
Never used anything like this in my life! After just days of using it on my lawn, it was the most green it has EVER been.
Now using it every 2 weeks.
Thanks plant doctor!
Great for the added green
By: Mitchell on 1 December 2020
This product proves itself time and time again. Anytime I’m looking for that hit of added green I add it in to the mix and within a day have a solid shade better than I had. Definitely recommend having this in your kit!
Special Mix Product 4
By: Ron on 17 November 2020

A Deeper Green
By: Scott on 15 November 2020
I have been using Liquid Iron on my lawn since my reno in September. Its given my grass a deeper green. The neighbours keep asking what I'm doing to make it look so good.
Value For Money and a Great Product
By: Chris on 12 November 2020
I have tried a few different Liquid Iron products and I have found this works the best for me. Overnight I noticed the beginning of the change then after 2 or 3 days the difference was amazing. Well worth the money indeed!
Green is getting greener
By: Sunny on 9 November 2020

Green to dark green quick
By: Jean on 6 November 2020
Happy with this product. Need to be careful as it stains pathways. Take a little practice to get it even but its effective.
The grass is greener
By: Steve on 30 October 2020
Terrific product. 2-3 days after application and the lawn is looking green and lush. It is great to use in the days leading up to a BBQ or having company over. 4 litres of this will last a long time and results are definately worth it. Can be mixed with other products if you want to reduce labour time, but I find it best to apply as a stand alone product.
Great value product
By: Kirsty on 20 October 2020
Cheaper and better than any other liquid iron I have tried
Green it up!!!
By: Mitch on 20 September 2020
You want dark green lawn then this is the key. Great to give the lawn that dark green boost.
Use it for quick boost of green colour
By: Vijayant on 19 September 2020
I was amazed to see the results of this product first time I used it. It makes the lawn go deep green within few hours of application. Very easy to use in an old seasol spray bottle.
Such a good product
By: Jerome on 27 July 2020
Can be used as a foliar spray on just about anything with visible results in only days. Iron does stain paths, bluestone etc so watch any overspray and wash off immediately. My lawn and lily pilly's in particular love this stuff!
By: Brandon on 23 July 2020
Got it in my Ben Sims pack. Absolutely stoked with the results
By: Michael on 22 July 2020

Plus supporting a local business make it the purchase even better. Thanks guys!

By: Brad on 8 May 2020
Applied Liquid Iron to my lawn and within two days it was noticeably greener, very happy with the product.
By: Steven on 29 February 2020
You want green lawn, well this stuff works a treat. A must have for every lawn lover.
By: Kyle on 20 December 2019
I bought this product in a bundle but tested it seperately to see how it worked as I was wondering if my lawn would react being I am on an old bore that is quite irony as it is. I did not see any real change in my lawn but I gave it to a neighbour who waters on scheme water and got him to just treat half his lawn first. Within 2 days there was a considerable difference in the colour. The iron applied patch was far greener. If you just want to give your lawn that quick green up, this is the product.
Green all year around

Dark Green Lawn
By: Stephen on 29 March 2019
Most fertilizers contain a little iron, but you’ll need to supplement if you want the darkest green lawn you can get. I just laid a buffalo lawn, and it needs more iron than other types. This product works wonders

I'll be happy to stay on the lower doses, which means incredible value for money for me!
So Green has to be Seen
By: Michael on 2 January 2019
