How can I fill in low levels in my lawn without tearing out the grass?

Question

I need to level out the height differences in my back yard.

Answer 1

we used to cover the low spots with sand and water well, the grass will grow up through and the yard will be level

Answer 2

This is best when you do it in small increments over long periods of time.

Add 1/2" to 1" of soil, soil/sand mix or straight sand over the low spots. Allow the grass to completely recover and grow back.At least 4 mowings. Then repeat. Do this no more than 4 times during the growing season.

It is best to aerate your lawn before placing your first application.

To much at one time may casue root fungal problems.
