Hi! This was Myrtillocactus geometrizans.

@@lophoflora most common, but I found pc is indestructible. I am putting Fero Cactus on a pc right now!

@@cactuscapacity I have three pachanoi but I don't want to cut them. :)

This plant was the only one that germinated from his sowing. I grafted it onto Pereskiopsis and it gave me several pups. when the Pereskiopsis stopped supporting the weight of the plant I separated all the heads and grafted them on Myrtillocactus. One of the pups gave me flowers and and even a fruit with one seed. Which is strange because this plant should be self-sterile. I sowed the seed and it gave me a plant. Maybe I pollinated one of the flowers and I don't remember. :)

@@lophoflora I am amused by these situations, the dynamics are just! LOL!

Yes, I collect some sulfur powder with a brush and spread it over the fresh cut. The sulfur powder mixes with the moisture from the plant's flesh and dissolves, as if it were paint, and it is easy to cover the entire area. I use wettable sulfur, used as a fungicide and acaricide.

After the sulfur dries, I put a rooting hormone in gel form, let it dry a little and put it in a pot with akadama or pumice.
