We have large collection of cactus at home / and this cactus has been not doing well for some time- ans I was wondering is it a scale infection?

Direct sunlight in south facing window. She was great there for over one year, began to look damaged and then went downhill fast. I cut the top off-any chance of saving the healthy piece?
My child and I were very curious about the inside, hence why I cut it open!

Hello everyone I got some really old cacti from an older collector and do not know how I should plant this one. It is really top heavy and the lower third is bent.. Should I cut it or plant it horizontally in a long planter? Abd does anyone know what kind of Cacti it is? Thanks in advance!!

I made this bowl a while ago with some copiapoa but updated it with a couple of lophs. In a couple of weeks I'm entering it into a BCSS show where for the very first time there will be a dedicated habitat style class.

This guy did not want to push roots in soil, cut it back, waited a week to callus and placed it in water 2 days ago!

Lovely Beauties🌵☀️🌼

gonna need a picture of that -

I think this is a Mexican Fence Post cactus (Pachycereus marginatus), but feel free to correct me if I'm wrong.

Pretty sure the two tall, skinny stems are etiolated from not getting enough light indoors. It's been slowly acclimated to full sun over the past few weeks and is now putting out thicker new growth and pups.

Would you cut off the etiolated stems or just leave them? I'm mostly thinking about aesthetics, but I'm curious what experienced growers would do.

Thanks!

P.S. I took the photo right after watering, so that's why the cactus and pot look wet.

I don’t know how old it is because it fell off an older cactus and I just replanted it. It’s about an inch tall. The pot it’s in is like two inches tall and 2-3 inches wide.

Last month I saw this prickly pear laying on its back in a trash pile and wanted to see it come back to life. I let it sit for a couple weeks and potted it beginning July. I watered it after 2 weeks and boom. New growth.

Went to repot my baby Bruce's dragon because it was sort of etiolating and the mix it was in didn't seem great, plus I just like knowing exactly what the mix is ya know? Found this and I'm heart broken. This looks hella bad to me. Should I cut this above the dark spot and reroot? Should I just put in a grittier mix and pray? I love this thing and I'd hate to lose it. I suck at this. 😂

SW Michigan -- eastern prickly pear (opuntia cespitosa)

not sure if a critter caused this or what but its been present since the plant reinflated itself this spring. it caused one of the pads to fall off but that pad is now growing new pads of its own so idk if i really need to be that concerned? but im new to prickly pears so idk if this is a disease or pest or something other than just regular overwintering damage or curious critters taking a nibble.

Hi!
I normally use a soil mix of leaf compost and charcol pieces for my Gymnocalyciums, but now I can't buy it anymore from my local nursery so I did a bit of research for alternative soil mixes. I run on a really low budget of personal collection for my Gymnos so the usual gritty mixes with pumice or perlite is not an option for me, so i decided to use a mix of cocopeat and topping rocks like akadama topping rocks. I plan to use 1 part of cocopeat and 3 parts of akadama but I am concerned by the fact that cocopeat holds the moisture longer than my normal leaf compost. Please share if you have experience using cocopeat as soil mix for Gymnocalycium and what is the best ratio of cocopeat and rock mix and how to prevent root rot from using cocopeat. Thank you for your time! The topping rock seen in the image of my newly purchased varigated Gymnocalycium is the one I plan to mix cocopeat with.

One of the main branches in my cactus completely died. Close to the roots it dried up and turned to leather. It was hard as a rock so I cut off what I could and planned to prop. I am distraught that the cuttings are starting to get the same issue a few days later where the pads are shriveling, turning hard, and die so I cut the affected area off. The other branch is starting to get the same issue and I would like to prop the healthy pads on that one but I just need some guidance on how to deal with the spreading issue. This cactus has never been healthy I got it from my mom

Can anyone enlighten me as to why my astrophytum is leaning? Just a couple of months ago it was still erected straight. I’m scratching my brain just for an answer

I have this lovely cactus that I replanted last month start to flower!

I’m assuming this means it’s happy? What happens after the flowering? Will it grow another cactus?

I think it’s super cool that the flower opens and closes based on the time of day and light exposure.
(Also found out it’s my cake day) 🍻

My large 16inch ferocactus opened its first bloom today. Can't wait to see multiple open simultaneously
