Q.Yucca Gloriosa Outdoor Care
I have an outdoor Yucca gloriosa, about 4 years old, which flowered for the first time last summer. I cut off the flower stalk about 3 inches from its base in January, but due to the bad winter, many of the leaves look ‘rotted’ in the middle and the new growth (leaves from the old stem) seem not to be flourishing. The stem itself has become black and quite soft and I really don’t know what I can do to restore it to its former glory. Can you please help?
