Hi. I have maybe twenty firestick pencil cacti in pots on my porch. They are all doing great! But, they are getting so big that they droop, practically touching the ground. I am trying to grow them huge as can be, but they keep laying down. I'm not sure if I should prune, I want them bigger than me. Is this growth pattern going to achieve the results I want? Does anyone have any pictures of theirs they would like to share? Oh. and I'm new here, so, by the way, Hello. Thanks for anything.
