My neighbor dug up a small yucca that was not blooming. The roots of the plant look like dahlia tubers and she wants to know if she divides them, will they produce new plants? Also, the plant was in place about 4 years and never bloomed and really didn't grow much (except underground!). I think it wasn't getting good drainage. Would that account for the lack of bloom?

As for the blooming, it could be a lack of phosphorus in the soil.
