Our lawn has St. Augustine's grass. Photos of it are at
First, is it pretty much suffering from shade stress, or should I look for more wrong? The grass is green and growing well where it is growing, but nowhere is it very thick, and there are large bare spots, and no grass at all grows near the tree trunks or the house.
Second, what kinds of St. Augustine's are most resistant to shade, that I should be readily able to find in Austin, Texas? Our grass also has to be able to tolerate drought.
I'm reading it both ways; is St. Augustine's easily killed by shade, or more resistant to shade than other varieties of grass?
Third, there are photos of some runners that are distinctly above the ground. I'm not sure if they originally grew that way or if they got more exposed than they originally were in the course of sweeping up bird seed over the winter. St. Augustine runners grow every which way including straight up. Should I cover these with dirt, or put a layer of dirt underneath them?
Fourth, should I till the bare patches to encourage grass to take root? The ground is hard but water is still able to soak in. I understand there are limited things you can do to loosen the earth on a lawn with St. Augustine's because you can damage the runners.
Fifth, how do I prepare teh bare patches for sods of grass?
Thanks!
