Question
Cactus
Cactus  
Hello, my cactus has developed three shoots coming out which look like roots- I wondered if I was underwatering and it was a search for water. These shoots started appearing around September 2013. Can you say what is happening. Is there something Im doing wrong or should be doing to assist the plant?

Kind regards
Kenny

Answer
Hi Kenny,

I've written to cactus expert Mike Hellmann of the Henry Shaw Cactus and Succulent Society, along with a picture of your cactus.  Here is what I wrote:

Dear Mike,

I am a horticulturist in Baton Rouge, La.   I volunteer in plant identification and horticulture at AllExperts.com.  I received this picture from Kenny in the UK, and I would like to give him a more definite answer than I can find in a few hours research.  I have read a paper from the University of California stating  that desert cacti rarely develop aerial roots, and theorized that, when they occur, their function is probably to capture dew.  This looks like more of a structural/support  seeking adaptation to me, from the position of the roots and the size of the cactus and the pot.  
Any observations and advice you give to us will be greatly appreciated.
Sincerely,
Susan Tabor

Thanks, Kenny, for this very interesting question.  I look forward to learning along with you.  I will continue to pursue information about your cactus and will revise my answer as soon as possible.
