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.
As you said, they droop because they are getting too big/heavy. Thats natural, however if you want them to be tall, you will have to tie them to some trellice of some sort. I would recommend using stockings to tie them Ed
