When should you burn grass?
Furthermore, when should you not burn grass?
The weather is something that should be considered as the best time to burn grass is on a day that is low in humidity and has no wind. This will help you keep the fire under control. If the wind is at speeds of more than 10-20 miles per hour, you should not attempt to burn your lawn.
Keeping this in consideration, should I burn my grass?
Burning removes organic matter, dead leaves, blades of grass, and other natural material from resting on top of your grass. The sun will warm up the darkened, charred lawn quicker, increasing the soil temperature faster which will benefit your grass.
It gets leaves off the grass, which can die if the leaves are left on too long. There is less of a fire hazard, and fewer wet leaves which can contribute to mold in the air.
