I have a 2 yucca's sharing a pot, one is a lot smaller than the other and I noticed the smaller one's bark was peeling away from the actual stem of the tree. So, I thought it being dead, decided to remove it completely. Doing this, I noticed that beneath the original bark was roots growing down the length of the the outside of the trunk, which was hidden by the now removed bark. I guess this was all down to over watering (I'm gradually learning to hardly water them at all!) but will this be alright or do I have do anything to protect, help it grow, survive? Thank You! Glen
Just allow the stem to be open to the air.
It should heal on it's own.
Watch for any signs of insects or disease.
You can apply Neem Oil if you see a problem
