    It shouldn't be applied when conditions are as dry as it's been. The ground needs to be damp before application, and it needs watered in if there's no rain after a few days. Perhaps you've over applied too.
    It happens all the time I'm afraid. There are several threads re this = especially this year.
    It's a place where beautiful isn't enough of a word....

    The black is moss... and what fairygirl says, even application at the right rate, and plenty water, are essential

    Are you watering your lawn regularly?

    Otherwise I'm not sure this would have been worth applying. My lawn is now dried straw- not pretty but I prefer to save water than waste it on the lawn (lawns are remarkably tolerant and it'll pop back up bright and green again when the weather changes).

    (I've made the assumption that you're in the UK / heatwave zone).

    Black is areas that have been killed off: moss and weeds. This will die down and hopefully be replaced by grass. 

    What do you mean by marking the decking?

    The active ingredient which kills the moss is Ferrous sulphate which will cause rust stains which are difficult to remove.

    The pack of Evergreen 4 in 1 lawn treatment will have had instructions and warnings very similar to these file:///C:/Users/Alison/Downloads/Evergreen%20Lawn%20Sand%20Label.pdf

    You'll see it warns against applying in dry periods.  It also warns against walking on it until it's well watered in and not allowing it to get onto paving or other surfaces as it can cause staining.

    Yeah looked up about the marking and it’s the iron in the feed that marks up surfaces, found a rust remover and it seems to be working, garden wasn’t bone dry as I had watered it the day before applied, we’ve had a few rain showers this week but I’m going to give it a good soaking anyway, time will tell if it was worth doing but I seem to be finding more negative reports of using feed like this than positive. I did the walking briskly thing and never reapplied on any areas, fingers crossed

    If applied correctly it is a very good product and well worth doing. .

    I wonder how you are supposed to avoid walking on the area you've applied it to if you are using a spreader?

    The spreader is part of the handle but I thought I hadn’t walked over treated areas but my deck says different, a lot of the Black is gone today so I’m going to try a good raking
