Yellow powder on grass
Your grass is dieing
Your lawn can go yellow for a varity of reasons. like when objects are placed on it the grass starts lacking sunlight and goes yellow. or lack of water, too much pesticide or moles. maybe its not getting enough sunlight. Animal urine won't help either. If it starts going yellow water it or use lawn feeds. cutting grass does have a very harmful effect somtimes as when you cut it, it will lose a lot of moisture. so after cutting water it and or use lawn feed. Grass can recover.
If you cut your own grass and leave the cut grass on your lawn it acts like a self fertilizer
Lawn grass turns yellow not simply due to lack of water, but due to lack of fertilizing. I have had a well-watered yellow lawn that turned green within one week of fertilizing. The reason? Over-watering washes nutrients (fertilizers) down through the soil out of reach of the grass's roots.
The Esperanto words for grass and lawn are herbo and razeno.
no you should not mow you lawn on wet grass
If it's a pile of grass left on the lawn after you mow it, cal it a clump of grass.
