go to the store and get some zipties and string that wont fall apart when it gets wet. like nylon string. also get a big pack of these clips
make a loop on one end of a piece of string thats about a foot or two long. put a ziptie through the loop, and tie that ziptie around a branch. put it close to the end of the branch, but not too close so it slides off. then pull the string down so the branch bends(dont break it), and use the clips to hold it to the pot.
do this all the way around the plant. instead of using a million clips, i like to bring 3 strings together for each clip. also you can tie like 3 or 4 zipties together and put one end on the branch thats already bent down. the other end attaches to another upper branch, pulling that down also. this way you dont have to keep adding strings
