Splitting an Adam's Needle, Yucca Filamentoas
I recently moved into a new house and in the front is a giant Yucca Filamentoas or adam's needle.
There are 6 flowering stalks and I think there are 8-10 individual off shoots.
It seems to need to be split as it is very large and crowding itself out.
How do I split it and when is the best time to split it.
(I am in Southern Ontario)
