im just woundering when do you cut back the flower of a yucca and also is there a best time for splitting the plant and does the plant stop flowering after x amount of years.

When the flower dies You can take a cutting of your yucca a t any time or place just stick the cutting in damp soil

We are in a cold climate, so our yuccas live inside. When the small green shoots appear, we cut them out of the woody trunk carefully with a sharp knife, dip them in rooting mix and plant them in potting soil (just normal potting soil). So far, our babies have survived, although they grow slowly. That is, they are now around five inches tall (from 1 inch at re-potting) and they don't have a 'trunk'. They've been in their new pots for around a year. Hope this helps.

Do you know how to revive ailing yuccas? I was warned not to overwater my yuccas but I think I may be underwatering them as quite a few have developed brown or yellow leaves and are shrivelling up. Watering doesn't seem to help though. Any ideas?
