Grass around crepes

[RonB]

I need to mulch around some crepe myrtles but there is grass all the way to the trunks. What's the thing to do - shovel to remove it, mulch over the grass, maybe round-up the grass if it won't kill the tree .. ?

thanks,
Ron

Round-up will work. Use an edger to make a circle than spray inside.If you use enough Mulch you won't even know there was grass under it.
