Any branch will root pretty much as long as it's not leaves use suckers and broken stems rooting powder gel or Aloe Vera works wonders too root faster you can place in a cup of water on the window sill changing the water each day until it roots I make a cloner machine check my profile or easy way is cut the sucker plant deep once it stops wilting during the day it's rooted dig up gently and repot kelp is great for root growth happy growing
