Hey Guys. Kio, Great work bud, she looks happy happy
When it comes to following my tutorial, the U shaped spike is just 1 of a gazillion ways to do it. You can tie arms down as only1man suggested, you can weight them down, you can add 2"-2.5" sq screen above it and just not let it come through, etc. Like it says in the tutorial, GET CREATIVE. Twist ties work if there are things to tie to, zip ties, rubber bands, the list goes on.
A couple key points though. When attaching whatever you are doing to the plant, whether by tying around an arm, using an "s" hook to grab it, zip ties, whatever,....MAKE SURE you leave room for further growth of that limb (diameter wise).
Second point. If you have a plant that has developed nice healthy WOODY type stalks, you can do the bends in graduations. Bend it a little today,....little more tomorrow,..let it adjust,...little more the next day,...you get the point.
Good lucks guys and GROW 'EM UP!!
