The plant has bright green tubular, segmented leaves (modified stems?), similar to an Allocasuarina leaf although thicker and fleshier.
It exudes a milky, white sap when cut. No flowers observed over many years. The many segmented leaves trail for a couple of metres.
It sounds like it is a variety of Rhipsalis, perhaps Rhipsalis Species Pendent.
I have a beautiful hanging rhipsalis which I just noticed is oozing sap. I do not see any bugs or scales. I love this plant and have had it for years. Can I take it outside while it is still warm out and wash it? How do I get rid of the sap and make the plant healthy again, and how do I prevent this from happening again? I had not moved the plant or done anything different with it.
Yes, washing it would be a good idea. Make up a spray bottle with a solution of 1 teaspoon mild dish detergent to 2 cups water. Spray all over the plant, especially up onto the underside of the leaves, and down into the nooks and crannies in the center. Let it sit for 20 mins or so, then wash it all gently with a hose. Looking through a wide variety of rhipasalis info, I can't find any disease that produces "weeping sap." I think it's almost sure your plant has some kind of sucking insect - some scales or aphids are almost invisible, and it doesn't take but a few to start dripping that honeydew, which is easily mistaken for sap. Wash the plant in the same way, at weekly intervals for 4 weeks, and you should eradicate the little buggers.
Have had this plant for at least 12years. Plant hangs down about 5feet. Lately one of the long vines have begun to shrivel up, the stems have narrowed and become brittle. I repotted the plant (1st time) into a little larger pot thinking that it has become pot bound(it was). Was this correct? I water the plant once a week, it is out of bright sun and heat.
What you have done is fine. This should help the growth, and recovery. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/cacti-succulents/rhipsalis/rhipsalis-mistletoe-cactus.htm
Is it possible to cut down (in length) a rhipsalis mistletoe Cactus? Mine is over four feet long and I would like to shorten it without doing any harm.
You can prune these with very little worry. They respond well to pruning. You can, even, use this cut portion to start a new plant. This article will help: https://www.gardeningknowhow.com/ornamental/cacti-succulents/rhipsalis/rhipsalis-mistletoe-cactus.htm
Are these normal? I bought the cuttings about 5 weeks ago they're planted in a mixture of Perlite and potting mix. They get 10-12 hours of extra light a day and are now rooted. I water about once a week and mist them occasionally. you can only see the yellow spots if you hold them up to the light. (I live in Sweden.) Thank you regards Rhonda
No, they're not in intense light they're just under a lamp during the day with some other plants.The bulb isn't too bright. https://www.ljusochmiljo.se/product/gu10-cob-led-mr16-5w
The spots could be related to the intense light exposure. See the section "How To Grow and Care" in this article:
I have had my plant for over a year I am going to repot it , photos I have seen of the plant are all green my plant is dark.
Yours may be getting too much sun, that can darken foliage. Try moving it to a bright location without direct sun. If the leaves are dropping, you may have a root rot problem. In that case, repot as soon as possible in fresh succulent soil and clean container.
