Just noticed these white indentations on the leaves

It makes me wonder if the burning from soap residue theory is right. I don't see these in the first photo I posted.

Re: Aloidendron dichotomum losing leaves
Thanks for your response, but I don't think I can use fungicide indoors (Daconil says outdoors only), and it's probably too late if fungus is the cause.

Re: Aloidendron dichotomum losing leaves
I took more photos when the plant hasn't just been sprayed with soap. First photo is the same leaf, and then there is a batch of dead or dying leaves i removed that to me don't seem to exhibit any signs of pests

Re: Aloidendron dichotomum losing leaves
The leaves are extremely dry except for the times when I spray them with the soap. I happened to take the photo just after spraying them - excuse my foolish decision. I will take new photos later today. I am not aware of any indoors safe fungicide I could spray the plant with. I would expect fungus ...

Re: Aloidendron dichotomum losing leaves
By the tip of my finger? That's light reflecting off the soap I just sprinkled on it. It's difficult to take a good photo when the light is so bright. I will take some more tomorrow when the sun is out.

Aloidendron dichotomum losing leaves
I have a large A. dichotomum grown indoors in a sun room. It's been losing leaves unusually fast over the last month or so. They shrivel up at the base while the leaf body is still healthy. I removed 20 or so. I spotted a few mealybugs a few weeks before, but not since. I have been spraying the leav...

Re: Rot in M. geometrizans
Thanks for the info. I am just keeping all my plants indoors and installing a huge fancy light soon. If/when I overcome the pest problems I am hoping it will keep them easier to deal with. I suppose I should invest in a dehumidifier given our climate. I still have hope the vascular system is fine, b...

What sorts of things can I try instead?

Re: Rot in M. geometrizans
I found some neem oil-based fungicide in my supplies, but I am not sure if that's sufficient.

Re: Rot in M. geometrizans
I didn't think to disinfect between every cut, hmmm. I treated the cuts with hydrogen peroxide - another site indicated that would work for this purpose. I did check the cactus thoroughly for softness and even cut off a small healthy bit to look at the tissue inside for reference. Fungicide is a goo...

Re: Rot in M. geometrizans
I dug up and repotted the plant in fresh soil (equal parts granite, pumice and fir bark with a dash of compost). It was mostly dry with some mild dampness deeper in. I should probably water less often. I took some photos of the roots. https://imgur.com/a/Xbu6PGa The roots looked ok to me. I also kep...

Re: Rot in M. geometrizans
Yeah, in the second to last photo you can see a cut that's along the length of the trunk on the pieces on the right side, and the fibers of the orange part are fairly clearly visible. I am fairly confident it's bark-like tissue of some kind and not the yellow-brown rot. I also think that if I am wro...

Re: Rot in M. geometrizans
As for the brown tissue, the circular orange-ish bit in the center is wood-hard. I don't believe it's rot. I suppose I can cut the already removed top section further to see if it disappears.

Re: Rot in M. geometrizans
The substrate is fairly porous. I am reasonably confident it's drying out properly. I dug through the top inch of the soil today, and it's bone dry even though I watered 2 days ago. I have had the plant for 5 years, so it could be that moving 600 miles north changed the climate enough that I didn't ...
