Are your plants outside all year, Danbonsai? I am lucky that mine can stay out all year. Winter is dry here and I usually water, but not often. We've been pretty warm this winter, too.

You mention corking. I've seen none on the above plant (unless I am misunderstanding the process), but this one is full of it! So I keep this one in bright shade because I thought it was the sun causing it. This is from last year -

I would watch this closely for rot. As much as I admire the looks of these crested Euphorbia, I am a bit wary of grafted plants like this. Good luck with yours.

Thank you, Christopher. I was concerned about rot, too. I was surprised to find the split already callused and no sign of oozing latex. And I was checking the entire plant for soft places and especially the graft. I fully expect to need to remove it from the graft someday - if it doesn't remove itself. We bought these plants on a lark.

I WILL keep an eye on the plant, especially this summer during our wet season.

Crenda, no, I'm borderline zone 4/5, so my plants stay inside on west windowsills---50-60 F ( occasionally 45-55) during the winter months. Both of your pictures depict what I would call corking. If I water my plants in the winter months, even just a little sip, the results are very much like your two pics. So, no water since September...dry as a popcorn fart...and no corking. Not sure if your citrus temps would necessitate more H2O, but up here that spells trouble.

I've been gone for a couple of months, but here's an update on the split in my plant. Overall, the plant still looks good.

The split is more of a hole now. I gently probed the hole and did not find anything living there. It's still dry and hard, so I guess it is not rotting.

So - I guess I just keep watching it. I dread having to trim this off of the plant and rooting it, but I knew that day would come eventually with the grafted crest.
