How is the Epiphyllum plant cared for? When does Epiphyllum flower?

 I already wrote that more epiphyllum plants are blooming in my house this year (The Spring Flowering of Epiphyllum Begins). It's the second year I've had flowering. I bought 15 varieties of this plant from a lady who reproduces them and sells them through her Facebook profile. For 2 or 3 years there were no flowers. A year ago there was one plant. 

Last year, when the temperature outside settled above 10 degrees centigrade in the night, I put all the epiphyllum plants outside on the terrace. I must say that the summer was not excessively hot and it rained a couple of times.

In autumn, I took them in the veranda when the temperature dropped to 10 degrees Celsius outside. I last watered them in November and resumed watering in March.

Since the roots were not large (the cats knocked over some pots), I left everything in the old pots even if I thought the plants were too big for them. I have to say, I was a little disappointed and didn't pay much attention to the epiphyllums.

In autumn and then in spring I watered all the plants with water from the sulfur spring which is nearby. It's very good for plants, I noticed. That's all this year. 

The flowers usually last two to three days. So, there is time to enjoy them. 

Flowering began on February 28th and today is April 5th. I'm still waiting for some buds that haven't opened.

Unfortunately, I don't remember the names of the varieties of epiphyllum I bought. I have the list of names, but I don't remember what they are.
