Well, the pad-parts look good...even have some buds, it looks like (?? can't tell, too dark-- might be past flowering already and that's developing fruit??)...
Do they get "stems" like that in warmer places? Now and then you'll see them growing here (Wisconsin), but they are always sort of low-down, on the ground and sprawling. If I had to guess, I would say it is--
but since it's not a common plant here--
That's good stuff to feed. How old is your sulcata? I have a 10 inch sulcata and I scrape off the spines and throw it in the pen. He just munches on it for a few days.
No it will die ! But if you cut off one pad and put on the window sill for 24 a- 48 hrs to let it dry at the cut then plant it in a flower pot and wait about a week then give it a small cup ( shot glass ) of water
Here's how I do it:
1. Cut off a big healthy fibrous pad. Preferably one that is at least a year or two old.
2. Let is sit somewhere dry and well ventilated, but out of the sun for at least two weeks.
3. Dig a deep hole in some dry dirt in a sunny spot somewhere, or use a pot. Most potting soil, even cactus potting soil comes a bit wet, so if you are using bagged soil and a pot, put your soil in your pot in direct sun all day everyday and stir it every once in a while to dry it all out.
4. Back fill most of your deep hole and sink the new pad in the hole, upright, about a third to half way down.
5. Don't do anything else for a month. NO water. Just let it bake in the sun in dry dirt.
6. After a month you can start to water. I water mine once a week in warm weather, twice a week in hot weather, and not at all over winter where they cease all growth.
Here is how my brother does it. He whacks the ones on his fence line with a lawn mower or a weed eater if the mower can't reach. A few weeks later there are twice as many. Wash, rinse and repeat until his fence line is loaded with them. Of course, I hear the above two methods work pretty good as well, lol.
