How many grams of iron per liter water do you all use? There is no subscription on the packaging and the last time I used it it was definitely to much as some parts of the grass died after the application.

This thread has it in oz instead of grams.

Thanks again @g-man That would be about 120-130 grams per 4 liters for 90 square metres. Or 30 grams per liter.

And would it be possible to mix in a post emergent with the iron?

Anyone who has experience with this?

And just another brainwave about using iron on your lawn. The iron gives the lawn a darker green colour. What about the absorption of heat on a darker colour and therefore a higher rate of evaporation of moist in the soil? Legit or just some stupid brainfart?

I haven't tried it. I know you can with some but there is a chance of the iron or some new compound being formed and precipitating out. It would be convenient to combine iron with fungicide, herbicide, humates, pgr, and fert. That would be a one and done mix! You can always mix a small amount in a jar and see what happens after 10 min. If the mix stays in solution, you're good. Problem is, you need to test all your herbicides since they can react differently.

I dont have experience doing this. I hardly use any post herbicide and if I do it is spot. I make one gallon tank of triclopyr in the spring and one of wbg in the fall. I dont use the entire gallon either time.

I did a liquid iron,Air8,fungicide all in one app that worked out good. Pre measured everything based on my Sq ft and threw in a hose end sprayer.

But you probably use a prem. We don't have that kind of products. So I can only use a post and then do the whole lawn so I hit every little weed. But I guess i should probably just try and find out.....
