Iron sulphate

Hi all

I hope you can help me, I got 2 bags of ferrogranul 20 iron(+2) sulphate hydrate this evening in the local hardware store and while the guy there said to spread it dry by hand I am now having my doubts after some googling and am wondering if anybody here has used that specific stuff before and should it be diluted in water and sprayed rather than spread dry by hand?

Thanks in advance for any help.

Regards
Tommy

dilute it in very hot water and put it on with a knapsack sprayer, clean the sprayer after use do not allow it onto your cloths or paths as it will stain, If you spill it on the lawn it will burn the grass.

Thanks greengage for the advice, what ratio should I dilute it at ? Unfortunately the bags don't have any info like that on them Sad

I take it when you say don't spill it on the lawn, you mean in a concentrate form or when it is being dissolved in a bucket..

both, Using a sprayer it needs to be calibrated for the user and theres a bit of maths involved. Look if you get a jug that measures 1ltr of liquid fill it with powder dilute it in a bucket with very warm water add this to the sprayer and top up with cold water spray this on your lawn. (My sprayer holds 15 ltrs of liquid) after 3 days it should turn black now get a scarifer and remove the moss and thach that has built up and you can reseed any bald patches. It will only do good if your not happy add more powdre or less next time.

Just a quick follow up on this, I done as advised by Greengage and mixed the iron sulphate and applied it, then scarified a week later, spread some seed on it and gave it a feed a couple of days later of 7/6/17 and things are starting to green up nicely now, even if the growth is slow due to the weather. Smile

I still have some moss around one part of the lawn but will be working on that using a rake for a while I reckon as it was particularly bad.

once again thanks for all the help.

The grass grows faster at this time of the year than moss. The Iron Sulphate burns the moss but helps the grass to grow faster. In a months time the moss will have disappeared almost completely. The underlying cause for moss is shading and soil surface compaction. Spiking will help with aeration.
