Question
Can an ocotillo be pruned? If so, is there a certain time of year that is should be done?  My friend has 2 ocotillos that were transplanted over a year ago.  He has been watering them daily for 40 minutes. They are 5-6 feet tall, the upper part of them looks dead, however, the bottom does not.  Can the dead parts be cut off and if they are cut off will they survive?  This would only leave about 1-2 feet. Also, what is the rate of growth of an ocotillo.

Answer
Hello Berni,
Yes, you can prune ocotillo. Unlike cacti, these will not leave permanent scars. However, new growth may be expected coming from the roots, not the stems. Also, your friend seems to be making a big mistake. These plants are succulents. They should be given enough drought or they may rot. If you are asking in behalf of your friend, let him know that he needs to let the soil dry before watering again. Yes, you can remove the dead parts.
