New start for indoor Yucca
I was given a yucca plant about 25 years ago. Some years later, the plant appeared to be dead so my husband chopped the trunk into pieces to throw away. When we moved house in 2004, we discovered a piece of the trunk in our shed. It had sprouted a shoot at the side and was definitely alive. We replanted the piece and it did very well. It used to stand on our basement window sill until it outgrew the space. I then moved it to the floor and, without enough light, its lower leaves have died off.
The top leaves are very healthy and so I would like to remove the lower part of the trunk and allow the top section to grow.
I would appreciate any advice on the best way to achieve this please.
