I have a yucca that grew extremely tall, bent over to the point I was afraid the roots would pull out. It was about 5 feet of thick stalk with a bushel of green leaves only on top. Within the top of the leaves, the stem curved to make an S-shape. I cut the whole bushel off, leaving about about 4 inches of stem and repotted it. It's a humongous pom pom of leaves and is curving all around the pot. Did I just kill it? What can I do? Thank you for your help.
Though you can propagate the cutting of the Yucca, the technique that will insure success is in the link below.
