Allow it to dry out a little between waterings. It needs bright filtered light, I keep mine at a south facing window. Temp, well for non-blooming time normal room tempature should do, but to get it to bloom it needs dim lighting and cool temps to induce flowering. Fertilizer, while in the growing season fertilize lightly, when in non-growing season don't. Repot when it becomes a little rootbound, Pot Size, alway pot 1 inch bigger then root ball, no more! Use cactus mix, if in moist areas add more corse sand, 50 / 50.
Hope this helps, farmerted361:)

I just realized that what I had thought I had was a Christmas cactus, but it is really a Thanksgiving cactus.
Christmas cactus has more rounded edges to it's leaf segments, whereas Thanksgiving cactus has the little points.

Either way, here is my mom's secret for getting them to bloom- yes, they need a cold period to set buds. Let your plants spend the summer outdoors in a bright but shady spot, no direct sun...bring them in RIGHT BEFORE the first frost- you want them to spend a few chilly nights outdoors, that is what sets the buds. When you bring them in, place them in a bright (no direct sun) spot, and you should get flowers! Like farmer ted said, water when dry, which is how I water most plants.

Hi, ines_99
I do the same thing, setting them outside during the summer is great for them. Thanks for adding that info, since I forgot:) Also I'm looking for a dark purple flowered Christmas/Thanksgiving cactus if anyone has it.

BTW, I have a small collection of the following:
Thanksgiving,
Plus the added,
Hatiora: gaertneri Synonym: Rhipsalidopsis gaertneri (Easter Cactus)
Lepismium: monacantha Synonym:Rhipsalis monacantha

Rhipsalis:
crispata
pachyptera
paradoxa

I keep them all outside.

I have mine on my desk at the office. It is in a plastic pot. Every Monday Morning, when it is drier than dry, I put it in the sink, let water run thru it, then let it sit there to drain. Back on the desk it goes. The air conditioning is on, the overhead fan is on. Covered with blooms last year. Finally found out that all the ones I killed before was because I watered too much.

Hi, josette-sc 8
I would suspect that your office is brightly lit, and of stable conditions that promote its over all condition and growth. Further more some Christmas cactus and other cacti sold in stores are hybrids, and tend to be easier to grow then non-hybrids. Nearly all of my cacti are non-hybrids, and a few do pose a challange to me. To tell you the truth, I get a lot of questions about how I grow my plants, and most often about my cacti. I do relate that setting them outside may seam like a lot of work for most people, but the end result does show up in larger faster growth and more blooms for someone who lives this far north, in relation to that most cacti's southern origins.

Yes, brightly lit office - florescent bulbs. I roast in the summer and freeze in the winter LOL....guess the plant likes it. I still put it outside.....thanks for the tip. I don't know if it has a name - someone sent it to me.

My feeling is what in a name, as long as you like it that is all that matters:)
