Question
I'm the one asking the questions about the using the sugar for some new grass we are going to try.  You wanted the name...they call it Bermuda Tiff grass.  We haven't gotten it in yet.  Of course, for the first time in a lot of years, we got a lot of snow and ice for Easter.  We got the yard tilled, but not planted.  So I don't know anything about it yet.  Hopefully, this will do really well with the dogs.  And, yes I know the dogs didn't cause the rye and nut grass, I think bird seed did (my husband is no longer allowed to have the birdfeeder in the backyard), the dogs just happened to run down the good grass.  They are our children and worth the work.

Answer
Thanks Wynne;
I relly was trying to find out the name of that variety of Burmuda.
Now I can find it without the nurseryman looking at me like I am from another planet.LOL
About the bird feeders.
When you follow an organic program, it will not matter how many weed seeds hit the yard, they will not grow and thrive.
My hubby has bird feeders too, and the only stipulation I have is that he is NOT allowed to have feed with that black sunflower seeds in it.
I found out, some years ago, that when the birds eat the insides, and drop the hulls, like they all do, that the hulls of that black sunflower seed has a toxin in it, that kills ANY vewgetation growing there.
I think that is whay I can't get anything to grow in that arfea of my back yard, as well as Rowdy and Big Boy stomping it down, and too much shade.
The feed he was using it was full of that sunflower seeds.
Now he uses feed without that in it.
Also, to keep the squirrelsa and ay other fur bearing critter out of the bird feeders, you can sprinkle that chili pepper seed that you get in the spice section of the store, and that you sprinkle on pizza, in with the bird seeds. It won't bother the birds at all, but will keep furry intruders out of it.
Those seeds also ride the wind in, and if there are weeds in your neighbor's yard, they will seed your yard.
My next door neighbor must have been told weeds were a cash crop, because he had a whole yard full of them, and never even mowed much, so his yard seeded the entire neighborhood every year.
After I got the soil nice and rich with organics, his weeds didn't come up in my yard anymore.
