Q.My Yucca Elephantipes Has A Split Stem, Will It Recover?
I just bought a Yucca Elephantipes which was growing quite bent over and is very tall. I’ve propped it up by a wall but it appears the trunk has split vertically. Will it be able to recover from this? Is there something I can do to help it? It is otherwise healthy.

Your plant looks too thin for its height. Also, the leaves look a bit droopy. I can't tell where on the stem the split is, but I would recommend cutting the stem into several pieces and rooting them for new plants, basically starting over. You can cut off the top for one cutting, then wherever the split is, cut that out and discard. You can then make several more cuttings below the split (if it was near the top). Be sure the part that goes in the new soil is right side up, i.e., if it gets reversed it won't grow.
Use well draining soil such as for cactus or succulents. Keep it somewhat moist till roots develop, it will take a few weeks. Then cut back on watering.
