I have had this Nightblooming Cereus for 12 years, and it took 8 years before blooming and has always been healthy. I just noticed over the last month that some leaves are turning an orange color with some brown spots. Is this something to be worried about? The leaves feel healthy. There's nothing on them. See the photo, and you can enlarge to see the orangey color.
I am not sure what the problem is, and the plant looks generally healthy, but excessive light or nutrient deficiencies are two possibilities. It might have a slight sunburn, or it might need to be fed with a balanced fertilizer if you aren't doing so already.
If my night blooming cactus is 18 foot high, how old is it?
I would not be able to give you an age of your plant.
This article has growing and care information.
Our family has had Night Blooming Cereus Plants for decades, and have shared hundreds of cuttings. I decided to try to grow a plant from seed, after the last bloom on my plant. It's embarrassing to admit that I don't know what a sprout froma Night Blooming Cereus would look like. I had some early sprouts in the pot, but it soon became clear that some were just weeds. Does anybody have a photo of an actual sprout from seed?
This link has a picture of its closest relative, the dragonfruit: https://upload.wikimedia.org/wikipedia/commons/d/d8/Pitaya_%28seedling%29.jpg The seedling of it looks exactly like the seedling of the cereus. This will be what you are looking for. Here is an article on the care of these:https://www.gardeningknowhow.com/ornamental/cacti-succulents/night-blooming-cereus/night-blooming-cereus-cuttings.htm
What is the lowest temperature night-blooming cereus tolerates.
Generally, they will tolerate anything down until about 50 degrees. anything under this, and it will start to suffer. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/cacti-succulents/night-blooming-cereus/night-blooming-cereus.htm
Hello, I've had this cactus for about 3 1/2 years now, he's gotten quite large and has a few little sprouts coming up in the soil as well. Recently one of the larger prongs has started turning white and going soft from the bottom up and the four little sprouts have wilted and fallen over. I've never had a problem with this cactus before and my family and I love it and are fearful we might be losing it, does anyone know how to save the rest of it?
Does the white area feel soft or mushy, which would indicate rot? Also check the sprouts that have fallen over to see if they are mushy.

Removing the plant from its pot and checking to see whether the roots are mushy is probably necessary. You will also need to cut out any mushy aboveground parts of the plant as described in the article. If the roots are are mushy or overly moist, you can let them dry out overlight, then repot the cactus in clean soil and be careful not to overwater, since it will probably use less water while recovering.
If any of the small sprouts still seem healthy, you can use them to take a cutting:

my plant is very old and very tall and scraggy. It used to bloom but has not bloomed in several years. I keep it inside in a corner, it is too big to take in and out, it gets sun from the window near by, it looks healthy and keeps growing but doesn't bloom. I was told if I trim it it won't bloom. It hits the ceiling and is trelling around the window. Wht is it not blooming?
Regular pruning will keep the plant from becoming to leggy and heavy.
You may want to go ahead and start out with new plants from the cuttings.
Hallo, Can you identify the plant in the photo below - I believe it could be in the genus - Cereus, but are not quite sure what it is. It is a 'hanging' plant with 'litted' leaves. Night blooming, very fragrant flowers. The flowers and fragrance last only one night. Thank you Isabel
It does appear to be in the Cereus genus, but I would be unable to identify it exactly. You can take it to your local extension service, and they should be able to pinpoint it for you.
