There is no Grass under my live Oak tree, "Shade loving" ground cover wouldn't grow under my Live oak tree.... I have 3-4 large Pin Oaks along one side of my property. I have some clumping Bamboo also, great shade maker and privacy fence. I also have a Pecan Tree right next to my house, they built the Driveway around it, so it has to be pre 1978, this year it is so LOADED with Pecans it is dropping branches that weigh a ton. Last year it didn't produce, and the year before it didn't produce full Pecans, but this year the ones that are dropping are nice and full, hopefully they come out good when they are ripe.
