I am considering two options:
- Planting the cactus deeper, so as to cover the leg,
- cut the leg, dry the wound and re-root the cactus.
What do you advise to do in this situation?
Cactus on a thin leg
Cactus on a thin leg
I have high (about 45 cm above the ground) about 20 years old cacti echinopsis oxygona on a thin leg (about 6 cm in height, 4 cm in diameter) which currently does not withstand the weight of the cactus. The whole cactus is unstable.

Re: Cactus on a thin leg
Looks like it is on a graft to me? Probably Trichocereus stock, though why somebody would bother grafting E. oxygona I don't know except as a grafting exercise.
You can either fully bury the stock, or cut off the scion and root it down.
If you cut it off don't cut it off at the stock but an inch or so up the Echinopsis from the stock since the join is usually fairly lignified and does not produce roots too well. The piece of oxygona left on the stock will also produce offsets for propagation, or you can use these as grafting stocks themselves later.

Re: Cactus on a thin leg
I don't think it's a graft - just the oldest growth was quite thin (maybe low light / high fertiliser).
I thnk potting it in a rather biger pot, maybe with 10cm of top dressing (corase gravel stones etc) is the way to go. I'd expect the buried part to develop roots gradually.
The young growth on this looks very thin, as though it is curently not getting enough light. Indoors, it needs a sunny windowsill. In temperate climates, it will be OK in a sunny spot outdoors for the summer.

Re: Cactus on a thin leg
Cacti weren't grafted. This is the result of unfavorable conditions at the beginning.
Recently unfortunately they were also kept (spring and half a summer) in a dark room. There wasn't direct sun.
For a week they are outside the building.

Re: Cactus on a thin leg
It's unusual to get such an abrupt transition from one form of growth to another though, it's usually more club shaped when it happens? Anyway you seem to be getting some pups off the narrow growth, so just pot one of those up and see what you get. If same as the top part, it was just narrow growth.
