Question

Answer 1

Generally, sealing is considered an out of date practice. It tends to seal moisture to the cut area, which can make diseases worse. It was once thought to prevent it.

However, you can cut it down further to allow it to "harden off".

If and when the base sprouts pups, you can transplant them, or leave them to form a sort of "shrub":
