I had to move a yucca plant that was over 6 foot and decided to do this by cutting it in half. After a couple of months, three shoots appeared symmetrically around the top of the stem. Only one has gone on to produce lots of leaves the other two remain as shoots. This has been the case for 4 months.
The plant did get attacked by aphids which can't have helped (the stunted shoots look unaffected), but I think I have gotten rid of these now and I'm sure a larger pot would help, but I'm really limited on space. The plant is in an east facing window on the south coast of England.
Do you have any ideas?
