I've had my ponytail palm for over 30 years, which would be 30 years of mostly neglect; it gets some water every couple of weeks, unless I forget... LOL. I trim off the brown ends of the leaves, and if any turn totally brown I remove them.
Have to laugh when I think about the time that I first got this plant... it was very tiny and I had no idea what it would grow into, almost planted it in a bottle terrarium. Thankfully I changed my mind for some reason.
My point is -- no need to overcomplicate your life to grow this plant, if mine is still alive and thriving, it must be next to impossible to harm it.
