Hello,
Does anybody know what the best fungicide for adenium obesum? I used to live in Indonesia and have many adenium obesum collection, but I moved to the U.S about 6 month ago (zone 7b) and I'm worried that my adenium will have problem with fungi in the winter that will cause the root to rot. I used to use some kind of yellowish powder fungicide in Indonesia, it smell likes sulfur, I don't know the name though and I'm sure I can't find it here. Does anybody have any suggestion ?
Thank you so much.
