I live in houston tx.

You will have to spray the garden with string weed killer and let it die back, if you can get a mini digger in and scrap off the dead grass and weeds. Use a power Harrow and then sow a lawn seed number 2 or 3 is best or even a mixture! Then roll the whole lot, pray for some heat and some rain and it will start to grow within weeks!!

Thanks

Thank you very much

Hope it helps best of luck!!

Best choice is to give up on grass in shade and do a shade happy groundcover instead. When you try to grow plants against their natural requirement, they don't thrive.
