My Aunt had a Christmas Cactus she kept it in her living room, a room no one ever sat in except during holidays when family over flowed into it. She had it for many years. I was always amazed that it bloomed when it was supposed to.
My grandmother had an Easter cactus that she kept propagating from around 1910. Her children (6 of 9 that were living that I knew) all had these Easter cactus growing in Florida. I took some segments and planted them for decoration when I was in college at University of Florida where I went to the College of Electrical Engineering. My mom called me one day to ask if I had a cactus living. It seems that one thing or another (freezing outside primarily) had killed every known plant from my grandmother. I told her that I had a big bushy plant. I broke off segments and started new plants for old family members and for my immediate family too. I have several plants going now, but had a fright when I set them outside a few years ago and chipmunks ate them to the ground. Fortunately they came back and I have not put them outside again! My Christmas card from one brother and his wife about 10 years ago was their Easter cactus in bloom!
If it’s in the perfect spot, and you don’t move it and do nothing more than water it and lightly feed it they’ll perform beautifully for generations.
The bloom cycle is based on temp and daylight length, so they just do it all by themselves when inside temps change in the fall and they get less light.
Right now, the ones I’m ordering from FL are kept in the dark, setting buds so they’ll be ready to bloom between Thanksgiving and Christmas. They won’t ship them to me any other time of the year.
Same thing with Points. They’re hanging out in the dark now, coloring up. Those I get locally. I can’t even imagine being a Point grower. What a lot of work and fuss for such a dumb plant, LOL! (I feel the same way about the hot-house Mums I sell in the fall.)
