1. for Mulch

If you’ve not applied any chemical weedkiller recently on grasses, you can use dried grass clippings for mulching in the garden.
Spread on 2-3 cm thick layer near the base of plants.
Grass clipping mulch also limits evaporation and conserves water.

If you’re using fresh clippings as mulch, only lay ¼ inches thick layer. This will allow the grass to break down quickly before it begins to smell or rot. Thicker layers made of fresh grass clippings have a tendency to remain too wet and can invite mold and create smelly decay issues.
