Is My Ionantha Dead?
I ordered five Ionantha plants several months ago. Every week all five get soaked in rain water for one hour then dried together, then placed into jars near a window. All five plants get the exact same treatment. Four of the plants are healthy but one (Scaposa or Guatemalin, I forget) has totally dried up. The leaves aren't falling off, but there doesn't seem to be any life left in it. I tried soaking it again and it got soggy but then dried out again. It's completely brown and crusty except the very center, which is brown but not crispy. I keep misting it daily, but I'm wondering if it's beyond hope.
Is it dead? Why would one die but the others are still doing well? Is there anything I can do to get it to revive?
