Tricho spachianus problem

[Ferro]

Hi guys!
In 2012 I got a seedling of the plant wishing to see it flowering on a windowsill or in the balcony (that's all I have to offer my cactus plants). But since 2015 I've been having this problem:

I've rerooted it a few times, used some antifangus medicine - all in vain. The problem comes back again and again. Do I have to give up my tries to save the plant? No other plant (ca. 200 ps) has ever had this problem. New pups appear and grow all right, then (in a year or so) they start getting covered with the same dry epidermis...

Sometimes mites can cause skin like this or it's a fungus that persist. How high is the plant? Doesn't look like regular corking though.

Well, I first thought of red mites (and the like) but it isn't the most vulnerable plant (and species) in my collection... As I 've cut it time and again, it's pretty short now - about 33 cm high:

Looking unhappy...

Try using a systemic insecticide. Maybe it's some insects. I'm not really sure.

All right, I'll give it the last chance. And get rid of the plant if it hasn't come to normal life till the next winter.

Put it outside during summer, say from late April until September. That might be good for this plant. Assuming you don't have excess rains every day...
