I have a night-blooming cereus that is now very gangly and I would like to prune/trim it. I have been given cuttings before, but I don't know where to cut the plant to prune it. How do I propagate my night-blooming cereus? What kind of soil does it like?
You can take 6 to 9" cuttings during the growing season, spring thru summer.
Wrap the cuttings in a paper towel and let it sit in a cool area for a few days.
The cut end needs to become calloused.
Add 1 part perlite to 3 parts potting mix and insert the cutting upside down with the calloused end up into the moistened medium.
Place the pot in a bright, shady location and make sure the soil does not dry out.
It will take 3 to 6 weeks to grow roots.
Water weekly during the growing season and once a month during the winter.
