Q.What is the best soil for yucca?
Cactus soil ok? What about the ph? I live in the pinelands of South Jersey where the soil is on the acidic end. My plants were offshoots I received from a friend. Her plant is gorgeous. This I’m really hoping will revive.

Cactus soil is thinking in the right direction, though they don't really like acidic soil. You will have to "sweeten" it with dolomitic lime, and it should flourish.
