    I have been dealing with 2 monsters for 15 years. They are at least 60 years old and 6 feet across at the base.
    Tried thinning, leaving alone, and have always had grass. Yes I have a sprinkler system and I use Micro Life fertilizer twice a year. I have a couple of brown spots this year that will come back this spring.
    Tried the zoisa grass in the dogs run area last spring and it is almost all dirt again this year.

      No grass will grow in a dog run if you use it.

            more water, roots sucking all moisture out and out competing grass. Sun would be nice but even with more sun light I believe majority of your problem is lack of water for grass to survive. I have no idea what I am talking about and did not stay at a holiday inn. Use my advice as real advice at your own transgression.

              This, the best St. Augustine yards I have seen under large oaks seem to always have a sprinkler system. But that an get expensive.

                Oaks have 2 root systems. Deep stabilizer roots and a surface mat that looks like a fishing net. It brings in water and nutrients, and is twice as large at the canopy. 30' canopy - 60' roots. I have roots in 2 neighbors front yards.
                I watch the soil and never allow cracks from it getting dry, and I sprinkle one neighbors front yard when I do mine.

                Water - water - water.......

                  That's what Live Oaks do every March. It's normal.

                    St.Augustine is a "full sun" grass..It tolerates shade to a degree.

                      Try Palmetto St Augustine.

I trimmed limbs and planted sod only to have it die out in the second year. I finally gave up on turf grass directly under the trees. I surrounded them with edging and planted shade tolerant ground cover like giant Liriope and Asian jasmine.
                        Hard to grow grass in the shade. Good alternative offered here.

                          My local grass farm recommends Floratam to use under full shade trees.

                            Thanks everyone for your input. I am going to do some more trimming so that will help but I will also do more watering as well. The grass I have is San Augustine, is there a grass that I can plant with it that will grow better?

                              Amerishade is a hybrid st Augustine that was developed to thrive in full shade. Zoysia also does very well in full shade. I have a massive red oak in my front yard and my zoysia thrives under it

                                Do you buy those two in seed form or sod?
