Question
In your answer about propagation of Christmas cactus using cutting, you said that this cactus was the most difficult to propagate with cuttings.  I have a cactus that is about 10 years old and have been giving "babies" to family and friends for years.  I just pinch off 5 to 7 inch pieces at the joint and put them in regular potting soil.  I keep the soil moist (not wet) and within three to four weeks, the cuttings are sprouting new growth.  At that point, I know the cuttings have taken and I change to my usual care regimen.  The new plant blooms within the year.

Answer
Dear S,

In my experience they have been. Taking a cutting from a Trichocereus or a Stenocereus has been significantly more successful for me. Unfortunately I live in an extremely dry area (Phoenix, AZ) and unless you use evaporative cooling or happen to have a greenhouse, the lack of humidity makes propagating Schlumbergera or Epiphyllum (which are both “jungle cacti”) difficult.

There is also a desert Christmas cactus named Cylindropuntia leptocaulis which is much easier to propagate.  I do appreciate the information however as I am always looking for new techniques (you also might have a little greener thumb than I!). Thanks.

Sincerely,

Greg
