    i hgave heard that it is better to put it on when the grass is wet because the fertilizer sticks to the grass much better, however i would be cautious when rain is in the forecast because it could wash it right back off, best to schedule for after the rain when there is no rain in the forecast.

    Granular weed control is what you need to apply when the grass is wet.

    Fert MAY burn the grass if it sticks to the blades, better to apply when grass is dry, it will not start working till it gets rain/irrigation.

    If more is in the near forecast then go ahead and get it down. Whatever sticks to the leaves will get washed off.

    You can apply granular fert to wet grass. Won't hurt a thing. Spreader may get clogged and require some extra kicks, but you can apply it.

    We used to get started every morning spreading fert at about 8:00am. If we would have waited for the dew to dry, we'd have been waiting til noon on some days.

    Granular fert will not hurt wet grass.

    Fertilizer on wet leaves DEFINITELY CAN HARM grass

    Fertilizers are salts. Salts draw moisture. Fertilizer dust or liquid fert can draw moisture out of grass leaves, causing a burn and consequent browning of the leaves. Years ago when big green mostly used tanker trucks, I saw many a burned lawn in the summer.

    But right now it would likely be OK for brian in SD to apply to wet leaves, especially if more rain is coming to wash it off of leaves. It is usually the high N apps in warmer summer days that will give the noticeable burn.

    But if the grass is that wet, you are probably going to muck up the gate and impeller on your spreader, causing a poor and erratic distribution and flow rate.
