    Uhm.. I have moss over here on my lawn and I was reading Jim Lewis's post of how to correct moss..

    HE said to use Ferris Sulfate which is IRON, and I was wondering I was reading through the ingredients of LIME and it has Ferris sulfate / iron in it!

    So, I was wondering could I just dump lime onto my lawn with the moss and just rake up the black stuff and then seed it again?

    Heres the thread.

    Jims method is a good way of short term treatment of the issue. BUT imo there's no point in this "sweep under the mat" type treatment until the contributing factors for the mosses presence are diagnosed and taken care of. Unless you want to preform this kind of procedure reguarly. Take away the conditions that the Moss thrives in and you wont have to worry about it again.

    Lime doesn't have enough iron in it to control moss. 2% iron won't do it. The fert I use has 6% iron in it and that won't give a complete kill.

    You need to fix the cause of the moss before you spend any money to kill the moss. imo

    Jim Lewis is right on in his whole post! And he's from our neck of the woods.
    I use what I can get at HD as we really don't have a real ag supply place here. I use for moss, NuLife (from HD), 46.75 % Ferrous Sulfate Monohydrate. The bag says it's 14% iron. AS apposed to Moss- Out with it's 2%. It kills pretty well but I'm going to find a source for straight ferrous sulfate and give that a try.
    And remember to blow it all off any concrete as it stains big time.

    When I use lime, I use Lilly Miller Soil Sweet, 55% calcium carbonate, no iron.

    Ya, seems like I have to find a heavy concentrate of ferrous sulfate!

    Do you guys happen to know if Home Depot carries anything like that, if so what's it called that you guys use!

    I just compared a 1 gallon jug of Lily Miller Moss Out (liquid) I purchased at Home Depot to a 1 gallon jug of liquid iron purchased from an ag supplier. The moss out product has 9.75% mettalic iron, the ag supplier product has 6%.

    I just used it (the Lilly Miller) on a clients lawn and worked just fine. I cut the lawn short prior to applying the product and used a hose end sprayer to cover the entire lawn, hitting the areas with heavier moss a little harder. 1 gallon covers 2000 sq ft. The liquid is a little more of a pain to apply but with the granular type you have to make sure the lawn is damp first so the granules adhere to the moss. If the lawn is dry, you need to wet it down first for optimum results with a granular product.
