In this edition of We Get Questions, I lay it on the line when a Euphorbia gets advanced rot.
I have what I beleive is a Euphorbia based on the pictures on your website. Recetnly the plant starting turning a blackish color on some of the branches, they would then drie up and droop. I don’t know what is causing it and it’s starting to spread to other branches.
Is there anything I can to do stop it?
Attached are pictures of the top portion of the plant.
I cut off the other branches that had dried out. The plant sits near my front door and has been there for several years. And then all of a sudden, these problems started.
The plant has caught an infection, probably a virus, and it looks like it is too late to save it. You can try to save some uninfected branches if you like. Cut them clean, spray with hydrogen peroxide, let sit for 2 weeks, and then plant them in dry soil to root. Don’t reuse your existing infected pot or soil, use fresh and clean materials only.
Sorry I don’t have better news.
