Re: Help saving this "Corn Cob"
Surgery looks like all you can do. A lot of meat to choose from but make sure when you cut it's nice and green, without brown spots. Also you've got a lot of small offsets that can be rooted. Don't wait though, rot can go fast
Re: Help saving this "Corn Cob"
i tried to cut 1 offset 2 months ago & it got rotten too after a few weeks.
the base may live after i'll cut above it?
Re: Help saving this "Corn Cob"
Cut higher, above the rotten tissue. Surface have to be ideally fresh and sound light green. Apply sulfur powder. Put in empty glass and leave on the windowsill. Check sometimes, it will root within a month usually, then you can plant it and continue to grow as a usual succulent.
Re: Help saving this "Corn Cob"
And take off all the offsets, just in case the whole plant goes bad. And I don't suppose you could save that base...unless of course you manage to get a fresh cut that low, but I doubt it.

thanks guys
& why put it in empty glass? close the lid or what?

Re: Help saving this "Corn Cob"
Here's a French website on saving a rotting cactus with surgery. I used this on mine and it works well.

Re: Help saving this "Corn Cob"
This corn cob cactus is technically not a cactus. It is Euphorbia mammillaris. I've tried growing the variegated form of this a couple times. Unfortunately they seem to be a bit prone to rotting and once it gets in the plant it spreads fast. Don't feel too bad if you can't save it.
Re: Help saving this "Corn Cob"
The only thing you can do is cut the still good looking part of and try to reroot that. Cut well above the brown / black parts, so nothing internal that might have spread a bit further up could still be in the section you cut off. Once you have a cutting, just let the wound dry out well for a week or so and I would then put it in a pot with some soil and let it be until spring. By then see if any roots have already appeared, and then you might start to water a bit every now and then. Don't water it before that time. It can only cause rot. Although I don't have much experience rooting an Euphorbia. It will be harder than any cacti, probably.
Be careful when cutting an Euphorbia. Don't get the white sap in your eyes (be careful of splashing drops!), mouth or wounds on your hands.
