Is angular sharp sand the recommended method for leveling vs. sand/topsoil mix or some of my native red clay? I've been told soil filled into holes will smoother the bermunda where sand won't. I've also read where too much sand to level in one spot will create future watering issues ...

"NOT PURE SAND It is easy for a homeowner to level a lawn. The first task, however, is to unlearn what you see at a golf course. There, sand is commonly used to fill divots made by golf clubs. Since the soil beneath has a high percentage of sand, adding sand to the damaged spot doesn’t change the structural characteristics of the soil.

Normals lawns, though, are not built with a soil mix approved by United States Golf Association. We typically have soil that contains lots of clay. If you add pure sand on top of clay the drainage and growth characteristics of the soil are disjointed. Grass growing in the sand is more susceptible to drought and cold injury. Internal soil drainage is worsened.

HALF AND HALF You can easily make your own lawn patching soil by mixing sand and planting soil in a 1:1 proportion in your wheelbarrow. Some of the retail soil companies have gone so far as to package and sell such a mixture specifically labeled for lawn leveling."


I can continue cutting the lawn at 3-4" for the rest of this season and it sounds like that's the best thing for it.
Some on this thread from GA will say they have used sand but I think what Walter is saying is conventional wisdom around the country where the soil is clay. I like compost and try to keep it to 1/4' in depth for the most part when dressing the lawn. If you have some areas that are relatively small but deeper the bermuda will recover pretty quick.

What you could do is buy some quality top dress compost and fill in the worst low spots only. Let the grass come up there. Then later aerate and top dress/level the whole lawn at a later date.

What height are you wanting to maintain on your lawn?

Following the 1/3 rule, the mowing frequency is as such.

(mowing height/2) / growth rate. You can assume a well watered and fertilized bermuda will grow close to 1/4" a day.

So for example you want to keep the turf at 1.5"

1.5/2 = 0.75 ( so you would cut the grass before it reaches 2.25" so you only remove 0.75" when you mow @ 1.5.

.75 / 0.25 = 3

If the grass grows 1/4 ( 0.25) then you need to mow every 3 days to keep the grass at 1.5 inches.

You are better off biting the bullet and taking the grass down one time then maintain it than you are removing 40 to 50% of the blade each week all summer long.
