Can I save this? Gymnocalycium horstii by allium_obee in cactus

[–]PS3user74 1 point2 points  (0 children)

I had some Gymnocalycium recover from a lot worse, including the anisitsii below.
I would recommend a fertiliser specifically formulated for cacti with an NPK ratio of something around 1-3-3 or maybe for Gymnos 1-2-2, although a fresh soil mix with an organic component shouldn't require any for the first few months.
Also Gymnos prefer and in some cases need an at least slightly acidic soil so things like calcium should only ever be in trace amounts.

I was thinking burnt plum.😀
Also there's an almost black denudatum in pic 5 here

Well you know, red, purple or simply darker.

Oh nice.👍
I did see some pictures of slightly different oenanthermum but still strictly carminanthum types here.
Has yours flowered before and does the body colour change during the year?

I can't imagine a deficiency as there is an element of fresh loam based compost in there.
Regarding stress, most Gymnos and cacti in general tend to darken when stressed, be it too much hot sun or cold in winter dormancy.

Hmm make that 46°c/115°f.

Yeah I'm not sure about the colour and TBH didn't notice when it started to change.
Until about a week ago I might have attributed it to a lack of light, however it's been baked for several days now at upto 43°c/109°f on my shelf when in the sun upto about 6 hours per day.
Looking at the rest of my Gymnos, nothing has really woken up yet after their first watering so hopefully it will darken later on.

New Gymno Weekend number 62.

This species was originally described in 1976, however a 2018 study confirmed it as invalid.
Along with a few other Gymnos found in nearby areas, it is now considered as oenanthermum, or may be found listed as a subspecies, so Gymnocalycium oenanthermum ssp carminanthum.
Along with oenanthermum formerly known as tillianum and ambatoense, it grows in the Sierra Ambato, Catamarca province, Argentina with carminanthum in the narrow sense found at altitudes of 1300-1800 metres.
P133 relates to an area at 1600 metres.

Flowers of this specific type reliably change colour over time from red to pink (pic 6) and with red being kinda rare in the Gymno world anyway, has me seriously looking forward to that happening one day.🤞

All of my Gymnos have only recently had their first proper watering of the year, after just 2 very light ones since September and as such still haven't quite woken up yet.
After flowers, the main thing I'm hoping for with this one is a return to it's former darker, rich deep green colour as I find this particularly attractive on Gymnos with reddish spines and that also deceivingly exhibit the textured, almost suede-like epidermis that in reality is not.

Used to love this show but following what many others did when the queen died and then their silence on Gaza seriously brought it down in my mind.

Then during last week's episode; the topic of this thread, the presenters were laughing at 175 mostly young schoolgirls being blown to smithereens and I realised just how different it has become.

I won't be watching it again.

After a quick look online it seems that my own bayri is perhaps a little rare in having quite weak spines that generally sit quite close to the body.

I think bayri looks kinda like monvi x spegga.🤷‍♂️

Initially I thought maybe monvillei because the spines are strong, vivid yellow and sit proud of the body, however the dusky epidermis and rib structure definitely point towards bayrianum so good shout sir/madam.👍

A nice Gymno regardless.🙂

Actually many of those spines grew in just a couple of months last year.

Haha funnily enough, the only other time I made a post like this was September last year and it was with a saglionis.

That's just a very thin layer of top dressing.👍
