Hi everyone I need despite help with a brown mark that first shows up on the adenium leaf. This brown mark sends the leaf limp and slimy, seems to get into the vein and travel then to the stem and rot is obvious as it goes black and limp.
I have been trying to be very clean when I cut the stem off and have made sure I cut down far enough and then seal the stem with wood glue. This has become a real problem for me as it is spreading from plant to plant. It seems to be a disease of some kind could anyone help me with a cure please.
Thanks Maria
