Q.Euphorbia Canariensis. Impossible! Can’t Eliminate Rot!

Zone 91506 Burbank Los Angeles | Avidmigda added on July 2, 2023 | Answered

Dear BushDoctor, thank you for your wisdom and all you share. If you remember last week, we came to conclusion with your agreement that when we cut off rot, the toxic milk in the plant running down the plant stem creates further rot. Watching the size and flow and as rot begins it’s process of blackening the plant and that area – it seems absolutely correct. However – Look! After removing the rot and not allowing any milk to seep down or touch the plant anywhere – still….it is back. Reminder. 6 months ago this started when plant fell over and two small pieces broke off creating rot and this now endless cycle of slowly cutting the plant away until it’s now almost gone. So sad that this cyclical process is just making it all go bye bye. 1. WHAT IS CAUSING THIS? I read those articles you provided and all noted and nothing similar happening. 2. 1st fall off, break from wind? If I would have just left it alone, what would have happened? It is this cutting off of the rot that creates this endless cycle. 3. We need to think outside of the box here!!! The stems on these two were 6 feet. One is almost gone and the other has 3 feet left. WE ARE READY TO TRY SOMETHING, ANYTHING NEW AND DIFFERENT. Let’s Experiment. Better than this false expectation land. We must leave basic assumption to gain the solution. All of the rot is cut off each time. I take an extra inch off when removing rot. It still comes back. There must be a solution here. The Rule Cannot Be As It Appears Now: “The moment any size section of this plant breaks off, you can kiss that entire stem goodbye because no matter you do, the rot will take over it eventually” That cannot be. My sincerest deep appreciation for having access to your wisdom BushDoctor. My kindest regards to you.

Unfortunately, if you remember from the discussion, this will be a permanent issue, unfortunately. All we could hope for is that it will not spread with removal, and that there were no, current, chemicals for this kind of control. Unfortunately, it and all related plants must be removed if there is the inability to control the disease. Outside of this, it will be necessary to solarize the soil to rid the area of disease. Now would be the best time of year to do so!
