Omg heeellllpppp. The owner of my local plant shop gifted me a cutting from this beautiful looking glass begonia. The mother plant has survived in a small glass vase for roughly 15 years, completely happy and healthy to the point where the owner didn’t even want to repot her. I put this clipping in a bowl of leca, haven’t done anything else to her. She’s under artificial light just like she was in the shop. What can I do to help her???? I’ll die if she dies.
