Does anyone have experience with Draceana Draco? Specifically, when you think it's completely dead because it used to be 4 feet tall and then it loses every branch, the stem turns ash grey, and black, the roots are mush from rot and completely gone in their entirety, and then you leave it in the pot all summer outside in the pouring rain and 110 degrees for two weeks and it comes back to life after 3 months?
