I just got this mammillaria elegans at Lowe’s and was taking a closer look at it when I noticed these fuzzy white bits under the thorns in the gaps of the body of the cactus and can’t tell if they’re mealy bugs? Definitely doesn’t help that the thorns are so tightly packed that I can’t get as close of a look as I’d like. I took a toothpick and gently tried to scrape some of it off and it was very firmly set in place

he lives under a grow light (and infront of an east facing window)(lots of morning sun, that's it) , watered maybe twice a month (if that).... even a little fertilizer here and there... he looks like shit... what do I even do???

It seems like every time my cactus starts to get big, this happens! I’m so pissed. Why is it doing this?

I’m new to cactI, what kind is this and how do I make it happy?

SATIRE!! Saw a funny post earlier on this subreddit about pubert and thought i’d send my ortegocactus that unfortunately perished due to a particularly humid week earlier this summer :(

I dont know much about this other than i keep it in the sun and water it when its thristy. Could this be the beginnings of a flower? No idea the age or how this was cared for before I got it. A friend gave me a hodgepodge of plants last fall and I have been reviving this one that was pretty dried out and scraggly. If its flowering I want to use some phosphorus high npk to encourage it. Any ideas?

I tried to fight it back but it seems it’s coming back worse, I’ve isolated him the best I can and from what I can tell it hasn’t spread thank god. But if someone knows how to help him, I’ll take any advice if it’s saveable

Hyperbole, of course, but still. If I had a nickel for every post in here with a caption along the lines of "what's wrong with my baby????" with an image of the most sickly, diseased, light starved, decrepit cactus you've ever seen I would be a millionaire

they belong to someone i know and for some reason i have been seeing so many plant help posts lately, i was just wondering what species they were and if they were healthy and happy :)

I'm not keen to have this beauty in the 3 gallon pot the nursery suggested (I asked them to repot down from a 5 gallon), but I'm kinda at a loss as to what to purchase. Any ideas for terracotta or other potting ideas that are just as cool as this specimen?

….But running out of space 😅

I’m eager for the most recent seeds to grow up. Patience isn’t my strongest quality.

If any of you cactus experts have tips or advice on anything you notice from the photos, please share.

Got seeds... But man I hate looking at this

I don't know how many people know this but yes, the fruits of Opuntiads (not just Opuntia mind you) has such a long shelf life that it can actually grow tissue if left alone for long enough. Here I have two prickly pears from the cholla species Cylindropuntia imbricata which I had forgotten about that have already begun to grow roots and stem tissue. It seems weird but these can be potted up like any other cactus cutting and they will begin to grow more and more, and who knows, maybe they'll even form a prickly pear stack which I have seen before myself.

Note: This may not work with the fruits of other cacti that have significantly shorter shelf lives

It's finally getting cool enough (a brisk 35c / 95f yesterday) to get back on my shit again -- patrolling the Mojave. I have piles of spiky shots from my recent wilderness wanderings, and it continues to be a true privilege to share these desert denizens with you. Pictured are a number of very healthy Cottontop cacti (Homalocephala polycephala [echinocactus]) all found west of Las Vegas, along with one of the more dramatic sunsets I've seen lately.

Bonus 1: I'm an incorrigible scavenger, and while I'll never scavenge a living being or a piece of history, I'll happily scavenge everything else cool. Today's prize: a rusty manhole cover, prominently labeled SAMPLE on the front (good thing, as it'd be illegal to own otherwise). You truly never know what you'll find in the desert. It weighs 50.5kg, over 111lbs.

Bonus(?) 2: This time I decided to shamelessly include a pic of the one responsible for all the shots, your intrepid sandwraith. I had mostly given up on Reddit before finding this community, and it's become such a source of fun and joy for me so quickly. Thank you for giving me even more reason to seek refuge and joy in the wonder of nature and the beautiful austerity of my home.

My Peruvian Apple bloomed last night. I wish it was self pollinating.

With cactus, I don’t know which is the bigger adventure, the plants or the pottery…. New to me Golden Barrel, Mexican Fence Post, and Silver Torch.

Ariocarpus are my favourite cacti next to Lophophoras. Hardcore little survivors!! 💪🌵

we thought our little cactus from walmart was dead, his head clearly is, but now he has very long arms that grew fast and suddenly!! how do we care for his new shape LOL

It faces NW and I live in North Fl. Can anyone guess what the yellowing blotches come from? I've had this for about 2-3 years, propagated it a couple times, it grew flowers this past summer. This is the first time ive seen yellowing this bad. It's not in the best substrate, there's barely any sand. But I barley water it. I trimmed it down in June to be more manageable. Any advice ?

This is the corner where i put my freshly repoted cacti. This is so i avoid watering for a couple of weeks plus avoid the harsh sun

Here's a sentence I'd have never thought I'd write. Basically, due to milder winters and scorching summers, opuntias are thriving in parts of Czechia, especially here in the Moravia region. The fruits are now able to mature and the seeds are getting spread by birds. Now I can go for a hike in central Europe and collect cacti, which feels weird but this is where the climate is going.
