SOS - Sick EUPHORBIA LACTEA GHOST

[mirko87]

Hi all,
Only last Sunday I got another Euphorbia, Lactea Ghost white.
Now after a week that has been with me is turning brown, where it looks like a stem that was already being cut (pic1)

perhaps to stop disease or just to propagate.

The plant stays indoor, in a very bright room where air circulation and humidity are balanced due to the presence of many other plants and haven't water it at all, as the soil was not completely dry when brought it home.

Reading around they're suggesting to cut the part turning brown before it spreads everywhere. Could be fungus? I don't really know.
Being this issue not in a stem but in the main trunk of the plant I just feel like it will harm the plant not only aesthetically but also for future growth.

Can you assist? What do you think it is ? and suggestion to rescue it
Only had the plant a week

Thanks

Not a cactus -- you should post this again in the Succulent Growing Help forum. Succulents don't have the same growing requirements as cacti, so if you repost there, you're likely to get more responses from people who grow only succulents.

Mirror Steve Johnson.
It looks like it has contracted a pathogen were the stem broke off. Cut out the decaying tissue with a clean knife. Treat it with sulfur. Do this sooner than later since it appears to be spreading quickly. As the plant heals and grows, the wound will diminish in size.
