Hello Folks, I have a nice forest cactus and it's leaves are starting to turn a burgandy-coloured red. The redness starts at the leaf edges and flares towards the center. Any idea what's going on here and how I can correct it? Thanks.
Hi Sjoerd, I found this list of cacti on the web but can't see Forest Cacti on it. :? Do you have a photograph of your plant by any chance?

Retrieved from http://en.wikipedia.org/wiki/Category:Cacti Category: Caryophyllales I have a succulent which changes colour from green to a dark, dark red called 'Blackhead'. Maybe your cacti is meant to change colour the way it does? It grows in Crete like a weed I'm told!!
Eileen I really like that succulent I wouldn't mind it growing like a weed around here!!LOL! Sjoerd I never heard of a forest cactus either, but I agree with Eileen maybe it's supposed to do what it's doing.
The Forest Cactus, in Latin Hiyah Guys.. Well, two of the ones that I have are called Zygocactus truncatus, Schlumbergera gaertneri. The one that seems to be turning red is the Zygocactus. Does this help? I hope that you have some ideas, cos I don't want to loose this baby. Heh heh heh.
Hi again, Found this: Common name: Thanksgiving cactus. Host range and symptoms First reported in Zygocactus truncatus; from Missoula, Montana, U.S.A.; by Chessin and Giri (1975). Natural host range and symptoms Symptoms persist. Zygocactus truncatus - reddening of pads. Transmission Virus transmitted by mechanical inoculation. Geographical distribution Found, but with no evidence of spread, in the U.S.A. Experimental host range Few (<3) families susceptible. Experimentally infected plants mostly show systemic mosaics, mottles, ringspots or necrosis. Diagnostically susceptible host species and symptoms Atriplex hastata - systemic leaf mottling. Chenopodium quinoa - necrotic local lesions, systemic mosaic. Chenopodium polyspermum - systemic leaf mottling. Chenopodium album, C. giganteum, C. urbicum - chlorotic or necrotic local lesions; not systemic. Hablitzia tamnoides - chlorotic local lesions; systemic green flecking. Diagnostically insusceptible host species Amaranthus tricolor, Chenopodium capitatum, C. hybridum, C. foliosum, Datura stramonium, Gomphrena globosa, Nicotiana tabacum, N. rustica, N. sylvestris, Phaseolus vulgaris. Maintenance and propagation hosts Chenopodium quinoa. Assay hosts (Local lesions or Whole plants) Chenopodium quinoa (L). Susceptible host species Amaranthus caudatus Atriplex hastata Chenopodium album Chenopodium giganteum Chenopodium polyspermum Chenopodium quinoa Chenopodium urbicum Hablitzia tamnoides Zygocactus truncatus Insusceptible host species Amaranthus tricolor Chenopodium capitatum Chenopodium foliosum Chenopodium hybridum Datura stramonium Gomphrena globosa Nicotiana glutinosa Nicotiana rustica Nicotiana sylvestris Nicotiana tabacum Phaseolus vulgaris Families containing susceptible hosts Amaranthaceae (1/3) Cactaceae (1/1) Chenopodiaceae (7/10) Families containing insusceptible hosts Amaranthaceae (2/3) Chenopodiaceae (3/10) Leguminosae-Papilionoideae (1/1) Solanaceae (5/5) Sources of host-range data Giri (1974). Sorry I couldn't e.mail all this information to you but I'm having problems composing and sending mail at the moment.
cactus probs Thanks Eileen, I appreciate your time and trouble with this subject. I'm not sure I understand the info you sent, tho. Heh heh heh. Could be I'm getting thick. Cheers...
All I could actually gather from it myself was that the red leaves indicate some sort of virus. It doesn't actually say what you can do though once the plant has contracted it and if it is cureable or not. :? If it was mine then I'd try cleaning the roots as much as possible and then re potting it in new compost. Maybe remove the red leaves too if it's possible and take cuttings from any healthy leaves. Sorry I can't be of any more help to you. There doesn't seem to be much on the web about these plants at all.
virus Ok Eileen. I appreciate your help. I was hopin gthat it would be the cold ...or too much water. oh well...
It is also burgundy coloured. I thought it looked unusual and that it was meant to be like that. I take it its not? The plant I knicked this bit from was neglected really, and kept in the shade.
These are supposed to be in the shade, actually they are a house plant, but can be kept on a porch or patio, no direct sunlight. I know that my new leaves come out red but get green with maturity. I have mine in deep shade under an oak tree, but I need to bring them in, it is too hot for them outside in La.
Hello Folks, Nice reading your messages about the red-leafed cactus, My plant is still alive but ALL the leaves are red.I don't know what to do with this thing, heh heh heh.I suppose I'll just have to wait and seewhat IT does....otherwise I suppose that I'll have to see if any leaves fall into my pocket the next time I visit a garden center...hahahaha. It really is an odd problem, but not fatal thus far. Cheers
Well since I have planted mine, it has turned alot more green with purple on the edges. Lokking forward to finding out what colour of flower it produces at christmas time!
It should be red flowers.In Texas they sometimes are called Christmas Cacti. Thats what my mom called them.
