I have read several articles on the night blooming cereus and none tell how much and when to water?. Also, mine is quite large and when should it be re-potted?
These will only need water when the soil is almost completely dry on top. This can make it impossible to give a definite time frame to water these, as this will depend on the temperature, humidity, and many other factors. So the best way to check is just to stick your finger in about an inch or two, and if it is dry down to that, then you can water again.
As far as when to repot... You will have to lift the plant out of container, and if the roots are circling the bottom, it will be time to transplant.
?My plant has a very long stem growing and nothing but what looks like roots. Do I cut this off?
Can you include a photo so that I may be able to identify what is going on? I will be able to tell you what to do with it when I know for sure what it is.
I live in the Greater Boston area. I got a 6'long cutting to start about 4 years ago. Its grown into a small shrub with several leaves in a small pot. I bring the plant in for winter and put it out during spring/summer. Last month it started growing these tall stems with tiny roots. Should I repot it into a bigger pot? When can I expect it to flower?
Can you include a photo? This can help me to identify the growth. They can require a very specific environment to flower, and fruit. This article will help in the meantime: https://www.gardeningknowhow.com/ornamental/cacti-succulents/night-blooming-cereus/night-blooming-cereus.htm
Hello, I bought three cuttings from a Night Blooming Cereus plant. I was told to plant with the cut side down a couple of inches deep in soil and to keep the soil very very slightly damp until it starts to root (about 2 weeks). I gave it a tiny bit of water just enough to make the soil every so slightly damp once in that two weeks (it's 2 weeks tomorrow) The tips of two of the leaves are turning black. One had turned black and dried out. When i touched it, it fell off the plant. The other is black but is still attached and not dried out. Also there are little flies hanging around it. They seem to jump more than fly, but they are definitely flies, and not fruit flies. Is it too late to save them? Thanks, Amanda
Not every cutting is successful, but don't give up!

This has come on suddenly but seems to be affecting the whole plant. There are some tiny bugs that stay around these small cacoon like things and also some long thin white bugs about 3/16" long. Lots of brown patches.
This looks like Scale or Mealy Bug.
Neem Oil is a good treatment.

Should I stake up or tie up my leaves on my night-blooming series they hang down and they look pitiful. Maybe that's the way it should look
Yes, they are a climbing cactus, and will appreciate being staked. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/cacti-succulents/night-blooming-cereus/night-blooming-cereus.htm
It is likely that the temperatures are not warm enough to support full flowering. Eventually, when it is older it may flower better as it adapts to your climate, which I assume is indoors. These will not survive even cool temperatures for very long. They will prefer when the temps. are into the 90's and above.
