Welcome to /r/cactus!
A community dedicated to the discussion of Cactaceae species and hybrids.
Rules:
- Please, please do not poach plants. Evidence of such results in a ban. Contact your local Fish and Wildlife service or Department of Agriculture for permits if they're available. Additionally, if a plant is growing on someone's property, consider asking the owner about it. Many people are more than willing to give away cuttings.
- Do not post about non-cacti. Deliberately posting about non-cacti will result in a warning, a temporary 60 day ban for 2x offenders, and a perma-ban for 3x offenders.
- Check the wiki and use the search before asking about care.
- No San Pedro ID requests, too often they result in poaching or stealing of cacti.
- No posts regarding the entheogenic or spiritual uses of cacti, check out /r/druggardening if you want to discuss such things.
- San Pedro growing related topics are OK, please do not report them unless they clearly violate the two rules above.

How to fix an etiolated opuntia
My game plan is to cut it down to where it starts to narrow and then cut that piece into several chunks and propagating those plus the pad. Is that the best way to go about it? Thanks

Etiolated Frailea pumila cactus.
So i got a cactus (first time). Kept it in the sun for about 2 months. Didn't see any growth. Then i learned about cactus getting sunburned (which was kinda surprising since the basic knowledge is cactus survive in bright sunlit deserts). So i took them to place where they get sunlight for a little less hours.
Noww they started growing really thin and long. At first i thought that might be how they grow big and started getting happy. But the growth took place longitudinally only and there was noo horizontal growth. Now they are tall and skinny headed.
The biggest one's around 4cm tall(with the etiolated part. 2cm without it. ) and 2cm wide. Will these parts grow in girth or should i just leave them or cut them? And whyy aren't they getting a little bigger? Do they flower? Will they flower if the etiolated parts are left like this?

Smitten with the hairys
Got these guy fresh out of the box at Walmart. No glued on flowers either. I assume and correct if I'm wrong more light = more hairs? I'm getting them adjusted to sunshine now and wondering . I'm in zone 5b. They will be outside summer inside winter. I plan to research them but assume in general care is the same for all four.

Help my Cac?
Dk what it is. 6 years old. Thought it was dead, threw it in garden to rot. 3 weeks later i cut it open for fun and its pretty green. I re potted. Will it live? Can you help me help this cac? (Flowered last season, turned this color when i watered on a night where it hit 30.🫢. Shape and color change convinced me it was dead)

Tips and propagation advice for optunia monacantha?
At least, I think that's what it is. I got it in a trade last fall and I am not a cactus girl. The top few inches of growth have been under my care. I don't know this species well, but I'm guessing the old growth was very etiolated and now the whole thing is top-heavy on a weak body.
Can I cut this anywhere, let it callous, and then place in soil? Or any other suggestions?
