Hi

I bought this yucca about 4 years ago and it followed me through 3 cities, and in 3 different pots.
Its trunk is the same height -30cm- as before, it still has 3 branches, but the leaves part has grown up a lot -now 1,20m- and it is now too heavy for its trunk size. The leaves are making the trunk fall on a regular basis.

I have tried planting bamboo vertical supports in the pot and tying the trunk with straw to the bamboo.

Is there a safe way to stabilize the trunk and make it lighter, should i take off the bottom leaves?
Thanks!
