Hi Margie, Although I’ve not personally had to transplant any of our red yuccas, I did a bit of research on the internet and it seems like you can transplant them best in Spring or early Summer. If you’re in a hot part of the country, you might want to wait for a cloudy day to transplant – somehow plants can do better when transplanted on those days. Apparently red yucca can be divided with a shovel or spade. For both transplanting and dividing — you want to make sure you dig at least 6 inches outside of the plant to make sure you can get as much of the root ball as possible to transplant. The key is getting the roots. Water a lot once transplanted, until you see that the red yucca has settled in nicely, which it should do as it is a succulent, and they transplant more easily than some other plant types. I also read a tip that you might want to gently tie up the spiky leaves of the red yucca to make it easier on yourself. Those tips can be pointy! Red yucca grows slowly, so once transplanted you will hopefully be all set for some time. Let me know how this goes for you, and thanks for asking!
