I live in North Texas and and have trouble growing hydrangeas

They love acid in the soil. Put coffee grinds around the bottom.

I hear you! I'd LOVE to have hydrangeas at the end of my driveway!

Hydrangeas like at least six hours of sun each day and plenty of water.

Hydrangea like acid soil. Texas soil is alkaline. You could try growing it in a container where you can change the soil. This link tells how to make soil acidic.

Our soil is very alkaline where I live in Southern Ontario and Hydrangeas grow and bloom very well. I do agree they like acidic soil as they then bloom in lovely shades of blue but alkaline is fine too. They like lots of water (thus, their name “hydra” = hydration) and will wilt somewhat on hot windy days but bounce back. I find the Paniculata type of Hydrangea really hardy and bloom every year. Annabelle is usually another reliable type too. There is a product you can add to the soil for blue blossoms (if that’s what you want) and you can also add a good layer of pine needles around the base of the shrub. When you buy a hydrangea, make a note of the type so you know how to prune it as some bloom on ”old wood” (meaning this year’s growth) and therefore IF you trim this year’s woody growth back a bit (say, in the Fall) you are removing NEXT year’s blooms! Some bloom on new wood. Keep the tags and record where you plant each type in the garden.

God Bless all of you ladies who have helped with this problem. First I am going to do a soil tests and then go on from there. Thank you so much...
