A lot of times we neglect our grass and after a white it get full of weed and it becomes unmanageable and needs to be fixed!
At this stage, it will need to be completely removed with the soil layer underneath and replaced with the new one.
After removing the bad layer of grass and soil, it will need a new top soil, then graded so its all leveled up. Then a new fresh layer of sod will be laid on top of the soil. It will need to be watered immediately especially if its too hot outside. the watering will continue twice a day for about 2 to 3 weeks until the grass holds itself into the soil.
