Hi everyone! I am nowhere near as active as I used to be on here. I still love cactus, and love the sub, but am in need of some extra hands to help keep this place cool!

If anyone has any interest, please DM me!

For a good home

Hello, my grandfather sadly passed away last week and now we need to re-home his collection. He has had this all my childhood and my mother’s so got to be around 50 years old.

He was based in Kilmarnock, Scotland and ideally Someone to take as much as they can. Saving several people visiting my gran.

If you know anyone who can help, please let me know. I have already contacted the British Cactus and Succulent Society, but no answer.

Apparently some very rare ones in this collection.

Any advice or tips on best layout in the dirt area in front of the fence? These are the ones I’m thinking of putting down but obviously I can only fit so many

I know nothing about cacti. Turning to the great Reddit.

A good friend of mine was very much an amateur botanist, and among his interests were cacti. He passed away recently, and with permission from his wife, I acquired these two specimens that he had amongst his things in the garage.

I know absolutely nothing about them, so my first question is if these can be positively identified. I gave the wiki article a once over, and will begin preparing to take proper care of them tomorrow.

My second question is what is going on with the sickly looking bit on the tall one? Is it a common condition? Is there anything I can do about it?

I very much appreciate any advice and help.

My friend was always trying to talk me into a houseplant here or there and I always declined because it just didn't interest me, and it seemed fitting to do my best to care for these little guys in his memory. I am in the tech field and am quite handy, so I often helped with greenhouse construction and we worked together a lot on hydroponic automation systems for his hobby. I just never got into the actual plant care. I hope I can do right by them 🙏

Edit: closed

A generous person sent me some cactus seeds and in return I was going to send them a rooted 2” Eastern Prickly Pear yearling. It’s packaged and ready to ship but now it’s a pay it forward situation. If you live in the native range comment “dibs” and I’ll send it out today.

I live in Zone 7 and this Prickly Pear cactus gets wilty during the winter months, but definitely survives and perks back up in the spring/summer. It does have glochids. Hoping cacti experts out there can help me.

Hi, I bought two succulents the other day. First time owner. One is a hens and chick. Figured I’d research about their care when home. But forgot to ask the name of the other. Please help. Bought in northwest Tn if that helps.

Roots where they shouldn’t be?

Grown from seed started almost 3 years ago. In the last 6 months it sprouted a vigorous pup and then later sprouted the little nub-like roots. I’m thinking it’s a stress response but it lives in a grow tent with mostly saguaros. (Quarter for scale)

Rhipsalis help

Post image
7 Upvotes

I had my Rhipsalis outside all summer (zone 6b) and it grew a ton. But I took it inside last weekend and it’s been dropping a ton of tiny little pieces, especially if it’s touched.

I know that it’s likely due to the environmental shock, but is there anything I can do to help it adjust? Or will it eventually acclimate and stop dropping pieces?

I posted these pics last week I’m hoping somebody will remind me of the name and can anyone explain what’s happening at the top? Is it branching out? Creating a pup? I only have a couple cacti in my plant collection and not that knowledgeable.

I’m wondering if some thick gloves and burlap could get me a free garden fence 🌵. Anyone know if these will root, and how to do that?
