I bought these from a woman on eBay. She had buy 5 get 5 free for $5.00 so I bought 10. These are totally different that the Cereus cuttings I got from a lady at a local nursery. The lady I bought them from said to just put them in some potting soil, water and give full sun and they take off which is kind of different than what I'm doing with the other cuttings. Are those tiny roots coming off of the cuttings? They look like the roots on some of my Stonecrop and all I do with those is set the roots into the soil and they start growing. Any and all ideas/suggestions would be greatly appreciated.

Unfortunately, not all Night Blooming Cereus are created equally. Night blooming cereus is a name given to any cactus that blooms at night. I can think of 8 or 10 cacti with this common name. Yours is some sort of Epiphyte.

You're right Daisy, I've since found out after posting my question that these are https://en.wikipedia.org/wiki/... as compared to the other cuttings I have growing https://en.wikipedia.org/wiki/...

I'm glad you worked it out. I was visualizing your first cuttings were something like San Pedro Cactus.

I'm trying to get smarter on all this stuff some day I hope to be able to rattle off scientific names like you guy do. These new cuttings are at least 12" long. I'm tempted to cut some of them in half. Do you think it would work to start the in some peat pots as long as the pots didn't deteriorate too quickly? I've got some small, I think they're 4" and some larger, I think they're 6" ones.

No, please keep peat away from these. Too moisture retentive.

Thanks Tiffany, then I guess its' multiples into as many pots as I can scrounge up to place them in. I guess it would still be ok to cut them in half to double my number? Should I mix a lot of my large perlite into the soil I'm going to use? How much water do these need when they're being rooted?

Well, I got all the selenicereus grandiflorus cuttings potted up yesterday. Now, do I put them in full sun or shade? If shade I can put them in the same greenhouse where I have my other Cereus cuttings that the humidity stays in the 50%+ range? How often do they need watered? I gave them a shower yesterday when I was done though not a drenching one. Any helpful hints or suggestions would be greatly appreciated. The potting soil I put them in has lots of large perlite mixed in.

Looks good! I would put them in mostly shade and water when dry. When you know roots have started, new growth is showing, water a bit more often.

Thanks Tiffany, shade it is. Have to clean out a place in the shaded greenhouse and move a table from the old one to this one. I just counted, I've got 42 of them potted. Not bad for a buy 5 for $5.00 get 5 free and I bought 10 and got 10 free.

Wow, IDK what you'll do with 42 huge plants (in a few yrs) but that's really cool!

I doubt I'll have 42 but, if I do, then I'll just give some away. Question of the day, where do I put these to ensure as many as possible root.

1) From what I've been reading this morning inside the shaded greenhouse with my Orchids, Epiphyllum and my Bryophyllum delagoense with high temps around 95 and 50%+ humidity would be the best. Please correct me if I'm wrong.

Do I let the soil pretty much dry out before watering again? Since these are all in nursery pots and have plenty of drainage holes do they get watered until they drain?
