Question

mystery cactus
Hello Maureen,

I am wondering if you can help me identify this cactus. It was grown in Canada by Sorensen Greenhouses, and I know the flower is fake and glued on.

Thank you!
Taylor

Answer
Dear Taylor,

I am not exactly sure which columnar cactus it is so I sent it along to some folks that will, so be patient.  I think it's an Echinocerus or Echinopsis butam not sure. In the mean time I would repot it in a pot with a hole at the bottom, the size is OK, in good well draining cactus medium.  The bigs stores always plant them in awful stuff.

The little dead arm next to the healthy one needs to be removed and you need to look for rot.  Hopefully it will separate from the other stalk.  if there is any black in the healthy stalk you will need to cutaway any rot and brush it with fungicide.  I'd leave it out for a few days to callous.  If the rot is in the roots than you probably can't save the plant.

By all mean gently remove that hideous straw flower.

I will get back to you about Genus and if you have any questions about potting let me know.

Well  was wrong. I'm told it is a Cleistocactus samaipatanus.  Same care tho.

Expertise

I can answer questions regarding the care and propagation of cactus and succulents and would actually group these together as folks often mistake one for the other and often their care is quite different. I also have a cold hardy cactus and succulent garden that has been quite successful. The subject in regard to classification of type is enormous and I wouldn't be able to answer all questions by any means. It is really IMPORTANT TO INCLUDE A PHOTO if at all possible and LET ME KNOW WHERE YOU ARE FROM, especially in terms of climate.

I have learned by reading books, by trial and error and by consulting with folks with much more knowledge. I have primarily grown C&S for the last 20 years.
