Euphorbia Monstrose Root Rot or Cork or What?

Post by Epclo »

I received a euphorbia monstrose (From a grower in California) on 9/19/20. I watered it once the other day. That’s it. Does this look like root rot? It doesn't seem squishy when I tap on it with a chopstick. I moved it to another pot today. The soil was dry. Is this normal? The photo below was taken today. The other photo was taken the day it arrived. I am in Tampa if humidity is a factor. It is under a grow light for 3 hours each night and gets partial sun in the daytime. Thanks

I do not know much about Euphorbia, but I do not think, that what you are experiencing is corking. That would take more than just a couple of days to show up and move.
Most likely the discolored stem is rotting and should be removed. Most likely, you can treat the plant similarly than what you would do with a cactus, i.e. take the plant out of the pot, check the root system and cut off the affected part, roots and stem.
Apply some disinfectant to the knife before you make the final cut and then let the plant with the clean wound rest on its side for a week or so.
You should not place it back into the soil, until the cut has healed and formed a protective callus layer. You could also apply a fungicide or sulfur powder to the cut.
By the way, it would probably be a good idea to ask the grower about what you should be doing now. She/he most likely has experienced that problem her/himself.
